Genus 4. PUPINA, F«>mrc£ 



Animal ; partaking of the characters of Cyclostoma and Helicina. 



Shell; cylindrical, mostly polished ; spire more or less obtuse at 

 the apex ; last whorl rather contracted ; aperture circular, with 

 the lip thickened, sometimes duplex, frequently cut near the 

 columella with a small funnel-shaped canal or fissure. Some- 

 times a distinct tube is formed against the body -whorl. Oper- 

 cidum horny. 



The twenty-seven species associated under this head, though affording 

 good generic distinctions, partake much of the characters of Cyclostoma 

 and Helicina. The very characteristic division of the former, known as 

 Cataulus, presents an indication of the tubular appendage of the lip so 

 curiously developed in the Pupince, subgenus Raphanlus ; and the more 

 polished and gaily-painted Pupince, with a simple fissure in the lip, ex- 

 hibit a link with the Helicina. 



No Pupina has been found in the Western Hemisphere. The habitats 

 of the species are well known, and range chiefly among the Philippine and 

 North Australian groups of islands.
