scholarly journals IV. On Tmesipteris Vieillardi, Dangeard, an erect terrestrial species from new caledonia

Tmesipteris Vieillardi , Dangeard, is one of those rare plants from the Pacific region, of which our knowledge has remained comparatively incomplete, owing chiefly to the difficulty of obtaining adequate material. As is well known, the genus Tmesipteris occurs under several forms, which Dangeard described as so many distinct species, but which are generally grouped under the name Tm. tannensis , Bernh. The usual habit of plants belonging to this genus is that of semi-erect or pendulous epiphytes, although specimens are frequently seen growing on the ground. But it is not commonly known that one of the forms is normally erect and terrestrial, only rarely growing as an epiphyte. In its external morphology and anatomy also Tm. Vieillardi shows some noteworthy points of difference from the remaining forms ( see Plate 5, figs. 1, 5, 8 and 10), and it is not unlikely that it represents the parent type from which the other forms may have arisen. The chief object of the present paper is to describe these distinctive features of Tm. Vieillardi and to discuss their bearing upon the affinities of this plant, both within the family Psilotacese and with other Pteridophytes. Advantage has been taken of this opportunity to publish photographs of the different “forms” of the genus, so as clearly to illustrate, for what they are worth, the individual differences in habit and external morphology.

Bryophytes are the second largest group of land plants and are also known as the amphibians of the plant kingdom. 67 species of bryophytes have been reported from select locations across the state of Gujrat. The status of family fissidentaceae which is a large moss family is being presented in this paper. Globally the family consists of 10 genera but only one genus, Fissidens Hedw. has been collected from Gujarat. Fissidens is characterized by a unique leaf structure and shows the presence of three distinct lamina, the dorsal, the ventral and the vaginant lamina. A total of 8 species of Fissidens have been reported from the state based on vegetative characters as no sporophyte stages were collected earlier. Species reported from the neighboring states also showed the absence of sporophytes. The identification of different species was difficult due to substantial overlap in vegetative characters. Hence a detailed study on the diversity of members of Fissidentaceae in Gujarat was carried out between November 2013 and February 2015. In present study 8 distinct species of Fissidens have been collected from different parts of the state. Three species Fissidens splachnobryoides Broth., Fissidens zollingerii Mont. and Fissidens curvato-involutus Dixon. have been identified while the other five are still to be identified. Fissidens zollingerii Mont. and Fissidens xiphoides M. Fleisch., which have been reported as distinct species are actually synonyms according to TROPICOS database. The presence of sexual reproductive structures and sporophytes for several Fissidens species are also being reported for the first time from the state.


Melanesia is important in any discussion concerned with the distribution of terrestrial Mollusca in the Pacific region, as a zone exhibiting an intermingling of faunas derived from different geographical areas. Along the chain of islands constituting Melanesia these faunal elements exhibit changing patterns consistent with island hopping across water gaps. Yet the numbers of species of Mollusca on these islands show a positive correlation with the size of the individual islands (figure 19) and not, as might be expected, with the distance of particular taxonomic groups from centres of dispersal. Variations in this pattern can be attributed to differences in the isolation of islands, ecological diversity and the paucity of collecting in many areas. It should be realized that the distributional patterns recorded for any particular taxon must reflect the frequency and density of collecting and the inadequacies of the systematics of the group, besides biological attributes of the taxon and the island. The limitations should not distract, however, from attempts to analyse the available information, instead they must serve as a guide to the difficulties involved.

A number of years ago I began to form and arrange in the Anatomical Museum of the University of Edinburgh a collection of the hair of the head to illustrate the varieties in colour and character which exist in the Races of Men. In a classification of the races based on the colour and characters of the hair, anthropologists have usually adopted the suggestion made by Bory de St Vincent, and have divided them into two groups: Leiotrichi, with straight, smooth hair; and Ulotrichi, with woolly or frizzly hair. Each of these again is capable of subdivision.In this memoir I intend especially to examine the Ulotrichi, which comprise two well-marked subdivisions. In one the hair is very short, and is arranged in small spiral tufts, the individual hairs in which are twisted on each other, a mat-like arrangement of compact spiral locks closely set together being the result. In the other the hair is moderately long, the locks are slender, curled or spirally twisted in a part of their length and terminate at the free end in a frizzly bush-like arrangement. Ulotrichous hair is found in various African races, in the aborigines of Tasmania, New Guinea, the Melanesian Islands in the Pacific, in the Negritos of the Malay Peninsula and of some of the islands of the Asiatic Archipelago. The Leiotrichi are Australians, Polynesians, Mongols, Malays, Indians, Arabs, Esquimaux and Europeans.

AbstractThere is a lack of experimental support for Linguistic Relativity Theory (LRT), which has not been tested in a South Pacific context. Fifty-two bilingual male (n = 26) and female Fijians read, and answered survey questions on the family dilemma, “An Unwanted Child?” - one group functioning in English and the other in Fijian. The group reading and answering in Fijian tended to place more emphasis on the rights of the extended family, whereas the group reading and responding in English placed more emphasis on the rights of the individual. These preliminary findings are consistent with LRT theory, and form the basis for more extended study, including perhaps a wider range of dilemmas and linguistic abilities (e.g., Fijians living in Australia).

For almost thirty years after the development of family therapy, the concurrent use of family and individual psychotherapy was seen as incompatible by leading proponents of each modality. Although recently the literature has revealed an increased willingness to utilize family and individual therapies concurrently, the decision for or against any such combination has been left largely to the intuition or bias of the individual clinician. This paper suggests the concurrent use of family and individual psychotherapies when disturbances of family structure and interaction co-exist with, reinforce, and are maintained by largely ego-syntonic internalized psychopathology (that is, the character defences of individual family members). It provides a rationale for integrating the concurrent therapies, and uses clinical examples to illustrate how each can potentiate the other. There is a discussion of indications and contraindications for the integrated use of concurrent family and individual therapy. From their attempts to apply these principles, the authors conclude that the experience for the family, the individual and the therapists is that the selective and integrated use of concurrent family and individual therapies can achieve more than can either therapy alone — the whole is greater than the sum of the parts.

So far no species of this family of Diptera have been described or recorded from the Samoan Islands. The acquisition of a species of Tabanus by Dr. P. A. Buxton and Mr. G. H. E. Hopkins is therefore of great interest.The Tabanidae of the Pacific Islands undoubtedly form an eastward extension of the family from Papua through Melanesia to Fiji ; various species are known from the Solomons, New Hebrides, New Caledonia, the Loyalties and Fiji, but the family is unrecorded from Tonga or islands to the eastward of Samoa. The Tabanidae thus represent a Papuo-Melanesian element in the Polynesian fauna. It might be mentioned here that two species of Tabanus, T. sidneyensis and T. nigriventris, were described by Macquart from “ Sidney Island,” which has been supposed to be Sidney Island in the Phoenix group. This locality is certainly erroneous ; most of the Diptera described as coming from there are known now to be common Australian forms and these two species are in all probability also Australian. The only other species recorded from Polynesia proper is T. insularis, Walker, described from the Sandwich Islands ; this record is also certainly wrong, since the group is not known to occur in these islands, of which the fauna has been extensively collected.

A new genus and species, Richerius marqueti gen. et sp. nov., of a crab of the family Hymenosomatidae MacLeay, 1838 are described from the inland waters of New Caledonia based on several specimens collected in two streams at altitudes of 180 m and 500 m, respectively. Richerius marqueti gen. et sp. nov. was compared to the other freshwater species known in New Caledonia, Odiomaris pilosus (A. Milne-Edwards, 1873), and to species of Amarinus Lucas, 1980, a genus comprising many freshwater species in New Zealand, Australia, Indonesia, the Philippines, and Papua New Guinea, but never recorded in New Caledonia. The barcode fragment of the COI mitochondrial gene was sequenced for seven specimens of R. marqueti gen. et sp. nov., and all sequences were deposited in GenBank. A brief and updated review of the New Caledonian marine and freshwater hymenosmatid fauna is provided.

Between 2000 and 2004, dengue virus type 1 (DENV-1) genotypes I and II from Asia were introduced into the Pacific region and co-circulated in some localities. Envelope protein gene sequences of DENV-1 from 12 patients infected on the island of New Caledonia were obtained, five of which carried genotype I viruses and six, genotype II viruses. One patient harboured a mixed infection, containing viruses assigned to both genotypes I and II, as well as a number of inter-genotypic recombinants. This is the first report of a population of dengue viruses isolated from a patient containing both parental and recombinant viruses.

Compared to other archipelagos of the Pacific, the New Caledonian Odonata fauna is rich and diverse with 56 valid species or subspecies (23 endemics, 41%) from eight families (four Zygoptera: Argiolestidae, Coenagrionidae, Isostictidae, Lestidae, and four Anisoptera: Aeshnidae, Corduliidae, Synthemistidae, Libellulidae) and 31 genera (including four endemics, 13%). In Zygoptera, we record 19 species including 12 endemics (63%), and among Anisoptera, we record 37 species or subspecies, including 11 endemics (30%). We removed five species from the list that had been erroneously recorded as occurring in New Caledonia: Tramea carolina (Linnaeus, 1763), Austroargiolestes icteromelas (Selys-Longchamps, 1862), Ischnura torresiana Tillyard, 1913, Xiphiagrion cyanomelas Selys-Longchamps, 1876 and Hemicordulia oceanica Selys-Longchamps, 1871. The occurrence of Tramea limbata (Desjardins, 1835) appears also doubtful, but we were unable to clarify to which taxon this record referred hence we excluded it from our update. From a biogeographic perspective, the New Caledonian fauna has mostly Australian affinities with some connections with southeast Asia and the Pacific region. We provide for each species, whenever information was available, a distribution map with a brief review of its known ecology, behaviour and phenology. We also evaluated each species’ conservation status, in light of known threats (range restriction, scarcity and human activity including altered water flow). We consider seventeen species (30%) endangered. The most immediate threats concern water pollution including alteration to the flow of water courses caused by mining, deforestation and fires. Invasive species, such as alien fish, may be predators of concern for odonata larva, although this has not yet been proven in New Caledonia.

Cruciglanis pacifici, gen. et sp. nov., is described from the Dagua and Anchicaya Rivers on the Pacific slope of Colombia. The new genus is differentiated from the other genera in the family by the presence of an ossified crucifix-shaped second basibranchial; ectopterygoid bone shaped as an inverted comma, with its distal end narrow and directed medially towards the mesopterygoid; anterior fontanel elongated, reaching a transverse line at sensory canal opening of the sphenotic bone; caudal fin emarginated with rounded edges and ventral lobe more developed than the dorsal lobe; caudal fin with a dark spot from its base and fused with the peduncular spot, covering the anterior three quarters of its length, distal rim totally hyaline. Coloration of the species is described in vivo, and the shared diagnostic characters with the other genera within the Pseudopimelodidae are discussed. The phylogenetic position of the new genus is proposed and new insights in the family interrelationships are presented.
