Pilsbry, Henry A.— Tryon"s Manual of Conchology, ser. ii, vol. xiv (pt. 54), pp. 

 65 — 128, pis. 16 — 21. Philadelphia: Academy of Natural Sciences. 



The genus Odonfosfomus, Beck, is concluded in the present part. In the sub- 

 genus Spixia, Pils. and Van., 0. vyrifurmis is a new name for 0. docringii, Kobelt, 

 1882, non. 0. docringii, Kobelt, 1878. Hyperaulux, Pils., Tomigencs, Spix, and 

 the interesting and peculiar genus Anostoma, F. de Wald., are next dealt with. 



The part concludes with an "Appendix to Bulimoid Snails." Here under Stropho- 

 cheihis. Spis, S. millcri v. kroiwi, v. Iher. ,and v. iguapcnsis, Pils., both from 

 Brazil, are new, as also S. caliis, from Brazil. Under the subgenus Borus, Alb. , 

 the following are new : S. yporanganus, v, Iher. and Pils., a species allied to S. 

 granulosus; S. hronni, Pfr. v. pergranulatus; S. fragiUor, v. Iher., all from Brazil. 

 Under the subgenus Thaumastus, Alb., >S'. granocinctus is a new name for the 

 Bulimus {Dryptus) filocindus, Rolle, 1901, non BuIlitais filocindus, Reuss, 1861. 



BBUtler, Bruno. — Die Anatomic von Paryphanta Jtochstettcri, Pfr. Zool. Jahrb. 

 (Abth. f. Morph.), 1901, Bd. 14, pp. 369 — 416, T. 26—29. 



Dr. Beutler has investigated the anatomy of Paryp)hanta hochstettci'i, which he 

 describes in some detail. The pharynx is a long, muscular sac whose internal 

 structure is similar to that in TcstaccUa. The oesophagus arises from the middle of 

 the pharynx, it is a long lube widening to form the stomach. From the contents it 

 would seem that the food consists partly of animal and partly of vegetable matter. 

 The description of the generative organs is far from correct, the terminology used 

 ancient, and the figure poor. The lung is a small, thin-walled sac. The central 

 nervous system consists of paired cerebral, buccal, and pedal ganglia, and a visceral 

 group of five ganglion, viz. paired pleural and parietal, and a single abdominal 

 ganglia. The cerebral ganglia have acce.ssory lobes which each send off a strand, 

 the well-known cerebral tubes of the embryo. The pedal ganglia are joined together 

 by two commissures and with them is a network of nerve fibres imbedded in the 

 pedal muscles ; numerous small ganglia are present in the network. 



Comparing Paryphanta with TcstaccUa, they are regarded as nearly related, the 

 former being nearer Testacella than Daudcbardia. The relative large shell comes 

 first in the phylogeneiic development of the Pulmonata, whereas a relatively small
