wards ; peristome and auricles white, thickened, slightly expanded, 

 the upper oblique, with narrow cut to the suture, covered by a 

 large curved somewhat triangular callus plate, extending to the 

 centre of the whorl, deflected at the edge, the lower canal cutting 

 the coluniellar horizontally, having a small impressed plate above. 



Length 3-J, breadth 2, height If, aperture 1 line. 



Hab. Palm Island, North-East Australia. 



The auricle at the upper part of the lip is the chief character 

 in this species ; it is cut to the suture, and the auricle extends up 

 to the centre of the penultimate whorl. It and Pupina Thom-

 species. Four specimens found under decayed leaves, in wet 

 ground.

Hab. Yule Island, New Guinea. 



This species is characteristic of the genus, having a narrow 

 spiral canal at the base of the coluniellar, and the umbilicus 

 bordered with an obtuse keel, which forms the outside of the 

 narrow canal at the base of the columellar ; it reminds one of 

 the genus Cataulus, with its keel. Named after Mr. H. Crosse, of 

 Paiis, Director of the French Journal de Conchyliologie.
