Since the publication of my revision of the genus Exenterus (U. S. Dept. Agr. Misc. Pub. No. 354, 1940) several pertinent items of interest have come to my attention.From the Canadian Department of Agriculture, through G. Stuart Walley, I have received specimens of two undescribe species, one in considerable nnmbers, the other represented by only a single specimen.

Specific Identity

Worms belonging to the genus Ascaris occur occasionally in the small intestine of sheep and lambs and have been reported both in Europe and America. They have been considered by some to belong to a distinct species, namely Ascaris ovis Rudolphi, and by others to be identical with Ascaris lumbricoides Linnaeus. The question of their specific identity is an interesting one and could not be considered as definitely settled one way or the other and though possibly the majority of helmin-thologists would subscribe to the view that the species is A. lumbricoides (vide Ransom 1911, p.25, and Ransom and Foster 1920, p. 30), others hold a different view; in fact Neuveu-Lemaire (1923) has recently published a paper in which he describes a single specimen of Ascaris from a goat as Ascaris ovis.

Morphological Differences

SummaryThe Red-tailed Newtonia Newtonia fanovanae, previously known from a single specimen from the eastern rainforest of central Madagascar, was rediscovered in October 1989 in the Marosohy Forest in the south-east of the island. In the study area, N. fanovanae occurs in the middle and upper section of the canopy of humid forest between 300 and 1,300 m. Ecological relationships with the other two sympatric Newtonia, amphichroa and brunneicauda, are discussed. The main morphological differences between fanovanae and the other two sympatric species are that the former has relatively long wings and short tarsi. The song of fanovanae is described and compared to other members of the genus. Our observations on the morphology, behaviour and vocalisations of N. fanovanae confirm its validity as a species.Le Newtonie à queue rouge Newtonia fanovanae jusqu'à presént uniquement connu d'un seul spécimen provenant de la partie orientale de la forêt tropicale du Madagascar central, fût redécouvert en octobre 1989 dans la forêt de Marosohy au sud-est de l'île. N. fanovanae fût rencontré dans les parties moyennes et supérieures du feuillage de la forêt humide entre 300 et 1,300 m d'altitude. Les relations écologiques avec les deux espèces sympatriques de Newtonia, amphichroa et brunneicauda sont discutées. Les différences morphologiques principales entre fanovanae et les deux espéces sympatriques sont que celle-ci a des ailes relativement longues et des tarses courts. Le chant de fanovanae est decrit et comparé avec celui d'autres membres du genre. Nos observations sur la morphologie, le comportement et les vocalizations de N. fanovanae confirment sa validité comme bonne espéce.

Time Of Year

[The Fungi collected in Kerguelen Island amount to 9 or 10 (the tenth being still an undetermined form). Dr. Hooker obtained 2 species in the winter (May and June) 1840; Mr. Moseley 3 in addition to the same, during summer (December and January) 1873-4; Mr. Eaton, also in summer, 5 determinable species, and 1 that could not be identified ( see footnote), besides the species found by Dr. Hooker. Until a few days before Midsummer ( i. e. Christmas) no Fungi were seen in the vicinage of the English Observatory Bay. The first to appear was the common mushroom, a single specimen of which was found on an island in the sound by some officers from H. M. S. “Volage.” Later in the summer the other four species came up in a few places on the mainland. They were not by any means of frequent occurrence, and probably scarcely any of them would be found at the time of year corresponding with the date of Dr. Hooker’s visit to the island.— A. E. Eaton. ]

A new genus and species of catshark is described based on a single specimen collected off Ambon in the Maluku Islands of eastern Indonesia. Akheilos suwartanai belongs to the subfamily Schroederichthyinae which differs from the other catsharks in a combination of: similar sized dorsal fins, supraorbital crests present, pseudosiphon present on claspers, broad subocular ridges under eyes, posterior nasal flaps present, tips of rostral cartilage fused into a rostral node. It represents the first record of this subfamily outside of the Americas. Akheilos differs from the other genus in the subfamily, Schroederichthys in a combination of: clasper groove not fused dorsally, ventral lobe of caudal fin produced, more intestinal valve turns, anal fin slightly larger than second dorsal fin, and in colour pattern.

Symphysanodon disii was described in 2008 from a single specimen collected in October 1999 from the Gulf of Aqaba. More recently, March 2008, four additional specimens of this species were collected in the Gulf. The following characters in combination distinguish S. disii from the other species in the genus: parapophyses on the first caudal vertebra, tubed scales in the lateral line 48 to 50, total number of first-arch gillrakers 34 to 37, sum of total number of gillrakers plus lateral-line scales (in individual specimens) 82 to 87, pectoral-fin rays 16 or 17, fleshy orbit diameter 7.2 to 8.3 % SL, and second anal-spine length 8.3 to 9.7 % SL. We redescribe S.disii, comment on S. pitondelafournaisei from the southwestern Indian Ocean off Reunion Island, and discuss sexual dimorphism in the genus.

Sigmaxinella cearense sp. nov. is described here on the basis of a single specimen collected in 2004 at Parque Estadual Marinho da Pedra da Risca do Meio, off Fortaleza, Ceará, Brazil. This is the first record of Sigmaxinella for the Atlantic Ocean. The new species differs from the other eleven Sigmaxinella species by the absence of raphides/microxea, and is the only species with a single category of styles as megascleres (mean length 435µm, mean width 12µm), and sigmas (mean length 21µm). The new species appears to be closer to Australian species of Sigmaxinella, on the basis of overall spicule morphology (mainly dimensions and categories of megascleres). This could be suggestive of a transpacific track for the colonization of the South Atlantic, instead of the shorter Agulhas track.Key words: Sigmaxinella, taxonomy, Parque Estadual da Pedra da Risca do Meio, sponge, new species, sandstone reef, Brazil

A New Species

The first record of the straptail fish, genus Macruronus, from South Africa was based on a single specimen captured off the Atlantic Cape coast and described as a new species, M. capensis Davies 1950. Davies did not examine specimens of the other extant nominal species in the genus, but based his conclusions solely on references to the original descriptions of M. novaezelandiae (Hector 1870) and M. magellanicus Lönnberg 1907. We show that all of the characters used by Davies (1950) to distinguish M. capensis from its congeners are in fact shared by the other nominal species of this genus. We also present molecular evidence from a Macruronus specimen recently caught off South Africa to support the conclusion that M. capensis is a junior synonym of M. novaezelandiae.

The following descriptions of five new genera and species of Tachinidae are based upon material received from several sources as indicated below. Most of the species have been standing in my collection for a number of years pending the accumulation of longer series. My thanks are due A. R. Brooks for the loan of some additional material recently discovered in the extensive tachinid collections in the Canadian Department of Agriculture. The type or paratype specimens, of the two species represented by this material, are returned for deposit in the Canadian Collection, as detailed under the descriptions.
