Outlines of Zoology.*— J. Arthur Thomson has revised his Manual 

 of Zoology, introducing a large number of new figures and a number of 

 modifications in his treatment of the subject. 



INVERTEBRATA. 



Fresh-water Microfauna from German East Africa.! — E. v. Da day 

 continues his interesting task, and reports a number of new Ostracods 

 (e.g. species of Stenocypris, Cypridella, and Potamocypris), thirty of which 

 are known as yet only from German East Africa, a new species of Macro- 

 biotus, and some Hydrachnids. 



Plankton of Spitzbergen.J — Hjalmar Broch deals with the plankton 

 from the Eisfjord of Spitzbergen. Some Tintinnidae, two Plutei of an 

 Ophiuroid — Say Ma and Eukrohnia hamata — various Copepods, the 

 Pteropod Limacina helicina, and the Appendicularian Fritillaria borealis, 

 are among the forms dealt with. The author describes three new species 

 of Peridinium, and has some interesting notes on a number of others. Of 

 particular importance are his observations on the form-changes associated 

 with growth. 



Mollusca. 



7- Gastropoda. 



Genus Cumanotus.§ — Nils Odhner compares Cumanotus beaumonti 

 from Plymouth with the Norwegian G. laticeps, and finds they are the 

 same. Thus he concludes that this genus of Nudibranchs has only one 

 species, viz. 0. beaumonti (Eliot, 1906), of which C. laticeps Odhner 1907 

 is a synonym. The species has consequently a wide distribution, being 

 obtained in England as well as in northern Norway. 



Structure of Phylliroe bucephala.|| — N. Vessichelli gives an account 

 of the nervous system, which bears a close resemblance to that of Aply- 

 siella and Tritonia and the Gymnosomata. The pedal, labial, cutaneous, 

 and other glands are described, and the structure of the gonads is dis- 

 cussed. The association of Phylliroe with Mnestra, with an Antho- 

 medusoid, and with Halistemma, is also discussed. 



Opisthobranchs of South Africa. f — K. Bergh reports on a collection 

 which adds greatly to the little that was known of South African Opis- 

 thobranchs. He establishes new species of Aplysia, Philine, Doridium, 

 Pleurobrancksea, Oscaniella, Archidoris, Doriopsis, Nembrotha, Tritonia, 

 Pleurophyllidea, and other genera, and contributes a large amount of 

 anatomical description.
