Very closely allied to C. intorta, but thin as paper, lacking com- 

 pletely a basal brown tract, having an almost vertical columella, 

 and of larger size. Like all other Cochlostylas it lives upon trees 

 near the beach, the leaves of which it twists into a bag for the 

 reception of its eggs. It is the only species of Cochlostyla found by 

 Semper on the island Limansaua. Hidalgo doubts its distinctness 

 from C. intorta.

 whorl flat above, and a little inflated around the umbilicus. Aper- 

 ture large, subquadrate; margins simple, joined by a very thin 

 callus. Alt. 14'8, gr. diam. 25'4, lesser 19'5 mill. ; apert. alt. 16,

Judging from the sharp lip, as well as the locality, this is no 

 Corasia. It may prove to be a Nanina. In the absence of certain 

 information it may as well remain where first described for the 

 present.

Shell globose, imperforate, the slender axis solid, thin, brittle, 

 white, with few whorls ; aperture lunar, lip thin, acute, fragile ; 

 columella slightly thickened, vertical, deeply inserted in the base. 



Animal like Cochlostyla, but the mantle reflexed over the acute 

 edge of the shell.
