Shell minute, thin, brown, perforated ; varying from Pupiform, 

 almost cylindrical, to globose-conoidal ; apex obtuse ; whorls 

 rounded, with delicate, irregular, cuticular riblets. Aperture 

 oblique, truncate-oval or rounded, the lip thin, simple or a little 

 expanded, broadly dilated at the columella, nearly closing the 

 umbilical perforation ; the columellar edge sometimes slightly project- 

 ing, but hardly dentate. Type Pupa lignicola Stol., pi. 14, figs. 41, 

 42. See also P. philippinicum Mlldffl, pi. 14, figs. 43, 44. 



Animal having very short eye peduncles and barely a trace of 

 tentacles. (Stol.^). Jaw, radula and genitalia unknown. 



Distribution, India, Borneo, Philippines. 



A group of uncertain position. Stoliczka" referred it to Pupidce; 

 v. Mollendorff to the Fruticicola series, near Acanthinula and Zoo- 

 genites. For the present I prefer to consider it a modification of 

 Pyramidula, comparable to the American group Ptychopatula ; but 

 I am not sure that it is not a group of Pupidce.
