necessarily becomes the type of Pupilla. Gastrodon Lowe, 1852, 

 not of Rafinesque, 181."), and Reinhardtin Boettger, 1878, are syn- 

 onymous. Lcmria Gray, 1840, was proposed for P. uinbiUcata and 

 P. anglica Fer.; if Laun'a is retained at all it must be for the latter, 

 in vvliich case Leiostyla Lowe, 1854, is synonymous. 



Encore Agassiz, in Charpentier, 1837, was proposed for P. tridens 

 and P. quadridens Drap. Gonodon Held, Dec, 1837, Ghondrula 

 Beck, 1838, and Chondrulus Westerlund, 1890, appear to be syn- 

 onymous. 



SpJtyradium Agassiz, 1837, has been adopted for P. edentula Drap., 

 by the process of elimination; Paludinella Lowe, 1852, not of Pfeif- 

 fer, 1841 ; Edentidina Clessin, 1876, not of PfeifFer, 1855 ; and Col- 

 umella Westerlund, 1876, are synonymous. Sphyradium (^ferrari) 

 Hartmann, 1840, has been named Coryna by Westerlund, 1887. 

 Spliyradium Martens, in Albers, 1860, is a synonym of Orcula Held. 



Paula H. and A. Adams, 1855, not of Blanchard, 1850, was re- 

 named Fauxulus by Schaufuss in 1869. P. capensis Kurr, appears 

 to be the type. 



Ptychochilus Boettger, 1880, founded on Pupa tnntilla Gould, 

 seems to have priority over Nesoptipa Pilsbry, 1900. Bifidaria 

 Sterki, in Pilsbry, 1891, contained two species, P. contracta Say and 

 P. servilis Gould. P. contracta being taken as type by Sterki in 



1892, for his section Albinula, P. servilis must be considered the type 

 of Bijidaria s. s., and not P. hordacea, for which Sterki's Euhijidaria, 



1893, will stand, if the sections are valid otherwise.

Eulota chishimana n. sp. 



Shell umbilicate, depressed globose, with conic spire, rather thin, 

 pale yellow, becoming white on the spire, the last whorl encircled 

 by three bands, that at the periphery dark chestnut and sharply de- 

 fined, the others much paler, reddish-brown, and indistinctly defined, 

 one in the middle of the base, the other on the upper surface, as- 

 cending the spire midway between sutures on the penult, whorl, or 

 obsolete except on the last whorl. There are also one or two dark
