 Whorls nearly 7, the embryonic increasing rapidly, convex, 

 minutely, indistinctly, spirally striate, the rest increasing slowly 

 and regularly, nearly flat, the last whorl long, tapering towards 

 the base. Aperture narrow, obliquely truncate-ovate. Parietal 

 lamella large, oblique. Columella narrow below, tumid above,

All the specimens were collected on the trunks of a species of 

 Urera, a foot or two above the ground. It was not abundant at 

 that time, and a later visit to the exact spot did not yield a sin- 

 gle specimen. Pilsbry and Spalding were along on the first trip, 

 but apparently neither collected specimens. 



This species is characterized by its very strong parietal lam- 

 ella and the columellar lamella?, which persist in the adult 

 stage. The columellar lamellae are rather long, fairly strong 

 and oblique ; the upper is situated just below the parietal wall.
