ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 455 



New Terrestrial IsopocL* — R. S. Bagnall describes Philosciapatiencei 

 sp. n., found in a hot-house of the Botanical Gardens, Kew. It strongly 

 resembles the common British Trichoniscus pusillus iu colour, shape, 

 size, and movements, but it seems to belong to the genus Philoscia, in 

 the vicinity of P. couchii. 



New Phyllopods.f — Joh. Thiele describes some interesting new 

 species — e.g. Apus frenzeli, from Argentina, A. madagassicus, Strepto- 

 cephalus distinctus, Leptestltcria vilUgera, Lynceus madagascarensis, 

 Gh irpcephalus sinensis. 



Species of Corophium.J — J. 0. Bradley describes Corophium 

 spinkoriie Stimpson and C. salmonis, in regard to which we have 

 hitherto had very vague information. He also gives a diagnostic key 

 for the genus, based on the work of Stebbing. 



Annulata. 



(Esophageal Pouches of Spionidae.§ — W. Salensky describes the 

 structure and development of these interesting pockets in larvae of 

 Polydora comuta, and in adults of Spin fuliginosus. They are very 

 similar to those previously described by the author in Polggordius and 

 Saccocirrus. In the Polydora larva there are five symmetrical pouches, 

 but only the first two persist as open clefts. They are comparable to 

 the pouches in Enteropneusts and Chordata, and they increase the 

 plausibility of the view that the Chordata evolved from an Annelid stock. 



Neuroglia in Leeches. || — A. W. Jakubski has made a comparative 

 histological study of the supporting tissue of the nervous system in various 

 Hirudinea — Hirudo medicinalis, Aulostomum gulo, Nephelis vulgaris, 

 Clepsine sexoculata, and Pontobdella muricata. 



Nematoh.elminth.es. 



Peculiar Nematode. 1[ — A. Porta describes Gnathostoma paronai sp.n. 

 from the intestine of Mm rajah, from the island of Mentawei. The 

 mouth has two lips, there are numerous rows of hooks on the head 

 and strange tridendate scales or lamellae covering the anterior two-thirds 

 of the body. The genus Gnathostoma was founded by Owen in 1836, 

 and is synonymous with Cheiracanthus Diesing (1839). 



Platyhelminthes. 



New Tapeworm in Moorhen.** — Pasquale Mola describes Tamia 

 marchali sp.n. from Galliaula chloropus, and suggests that the other host 

 is the Mollusc Cyrlostoma elegans.
