Among Gasteropod Molluscs the life-histories and development of the most highly evolved members, the terrestrial Pulmonates, have been less intensively studied than those of more primitive aquatic forms. This has been due in part to the technical difficulties involved in the permanent preparation of material for study, and in part to the fact that the investigator seeking for primitive features of phyletic interest is more likely to find these among more generalised species of Gasteropods than among those which are obviously adapted, both during the early stages of their development and in adult life, to a habitat far removed from the ancestral one.It is the purpose of this paper to present data bearing upon the life-history of a single species of land Pulmonate, Agriolimax agrestis L., to enlarge upon certain aspects of the embryology of this species, and to demonstrate the structural and functional changes of the larva which have accompanied the transition from an aquatic to a terrestrial breeding habit.

Townsend (1935) has described the egg of Synthesiomyia nudiseta and recorded the interesting fact that the larva forms a cocoon. The larval stages and the puparium do not appear to have been described. That this species was not among the larvae of some unknown muscids described by Banks (1912) is evident from the figures of the-posterior spiracles. The present communication provides an account of all the early stages.

Early stages from fertilized eggs to juveniles are important in the existence and development cycles of fish. At these stages, fish are still not fully developed, and are thus easily affected by environmental factors. Vietnam has a rich fish diversity, with ca. 3000 species, and fishery resources play significantly roles not only in the daily lives of local residents but also in national economic development. Ichthyological studies in Vietnam have focused mainly on matured fish while early life history has so far been less researched. This paper presents an overview of studies in Vietnam related to early stages of fish and provides an orientation for this field in future.

1. Neottiophilum praeustum (Meigen 1826) is an Acalypterate fly, the larva of which inhabits the nests of various birds, e.g. Greenfinches, Chaffinches, Linnets, Thrushes and Blackbirds.2. The structure of the early stages of this fly namely eggs, larva and pupa is here described for the first time.3. Hendel's view that Neottiophilum should be separated into a new family is confirmed.4. The larvae of Neottiophilum live as intermittent blood-sucking parasites upon the birds. Their feeding habits are similar to those of Phormia and Passeromyia.5. The structure of the pharynx in Cyclorhaphous Dipterous larvae gives important indications as to the mode of feeding. Those larvae which are provided with longitudinal ridges are saprophagous or living upon decomposed vegetable or animal substances, while those which are devoid of ridges are biontophagous or feeding upon living substances (parasites in plants and in animals, predaceous or living in the uterus of the mother).6. This generalisation, when applied to the study of myiasis in plants, animals and man, enables us to separate them into two categories: (1) primary or parasitic myiasis and (2) secondary or pseudoparasitic myiasis, these being either accidental (intestinal) or following upon bacterial infection.

This paper consists of two parts: (I) a complete account of the life-history and a description of early stages of Melinda cognata Meigen which I found here in Cambridge living as parasites on a common snail, Helicella virgata da Costa, and (II) a review of all observations made hitherto on the life-history of different flies feeding upon living or dead molluscs.

The life history of Brenthis montinus has long been a problem taxing the ingenuity of lepidopterists. Scudder made repeated efforts to secure the egg but never observed a female ovipositing. The egg figured in “The Butterflies of the Eastern United States” (Vol. 3, plate 64 f.38 and plate 67 f.16) was removed from the body of the ♀ (1863 Bost. Journ. Nat. History VII: 626; see also 1874 Geology of New Hampshire 339, 354).

On the 22nd June, 1901, I received from Mr. A. Kwiat, of Chicago, a batch of eggs of Arctia virguncula, Kirby. These eggs were laid on the 18th June and hatched on the 25th and 26th. The following notes on the early stages of the species were taken. A brief description of the mature larva was published by Mr. Coquillett, in the first number of Papilio, in 1881.
