CURRENT LITERATURE. 



Pilsbry, Henry A.— Tryon's Manual of Conchology, ser. ii, vol. xvi (pt. 61), pp. 



1-64, pis. 1-18. Philadephia : Academy of Natural Sciences. 



Dr. Pilsbry commences volume xvi with an account of the genus Anoma, 

 Albers, enumerating twenty species and twenty-two varieties, of which the fol- 

 lowing are new: A. adamsi, A. jarvisi, A. nitens (Cliitty), v. simpsoni, A. levis 

 (C.B.Ad.), V. balteata, and A. nigrescens (C.B.Ad.), v. leucosioma. There is a 

 useful " Key to vSpecies," and many of the forms are figured for the first time. 



Passing next to the genus Brack)/ podella. Beck (Type B. anfiperversa), 

 a short account is given of the anatomy. The generative organs are similar to 

 typical Urocoptis. In B. chemnitziana and agnesiana the penis is moderately 

 developed, with the vas deferens and retractor muscle apical. The vagina is 

 at least as long as the penis. The I'eceptaculum seminis is sub-globular, and its 

 duct long and slender. In the viviparous B. chemnitziana the uterus (the ovi- 

 ducal portion of the common duct) is capacious. The pharynx and salivary 

 glands are similar to those in Urocoptis, but the radular sheath is enormously 

 lengthened, stretching far into the visceral cavity. The free retractor muscles are 

 also not unlike those in Urocoptis, only they are united further at the proximal 

 end. 



There is no character of the shell common to all the forms of Brachy podella, 

 which will serve to separate the genus from all forms of Urocoptis. 



A key, founded upon shell-characters, to the various sub-genera of the genus is 

 given, and a new sub-genus Brevipedella (type B. imitatrix, n.sp.), is described, 

 then follow the following sub-genera : Amphicosimia, Pils. and Van., Strophina, 

 Morch, with B. latterradii (Grat.), v. strophina, nov., Liparotes, Pils., Siphono- 

 laeinus, Pils., and Gyraxis, Pils., with B. gouldiana (Pfr.), v. sericata, nov.
