species were formerly grouped in Pledotropis, but the lack of dart 

 sack and mucus glands widely sunders them from that group.

 ture small, oblique, peristome expanded. Soft parts unknown. 



A middle Chinese group of uncertain position. Mollendorff refers 

 it to Satsuma, Ancey to Buliminus, whilelHLeude and Gredler cut the 

 Gordian knot by removing the species from both genera.

Shell elevated- conic, many (eleven) whorled, upper whorls 

 spirally striate, the rest obliquely costulate and setigerous; apex 

 obtuse, mamillar ; base depressed ; peristome reflexed below, mar- 

 gins distant, connected by a callus. Type C. arfakiensis Tap.-Can. 

 rol. vii, p. 87. 



Soft parts unknown. Inhabits New Guinea. This peculiar snail 

 considered an ally of Trochomorphoides by Tapparone-Canefri. 

 'erhaps it may prove to belong to the Charopoid series.
