88 GASTROCOPTA, NORTH AMERICA, WEST INDIES. 



In his Trinidad list of 1893 Mr. Guppy remarked : " I think 

 it possible that the shell I described as Pupa auriformis, and 

 of which I never found more than a single specimen, may be 

 a variety or accidental form of this" [P. uvulifera]. The 

 original description follows : 



Pupa auriformis. Shell subperforate, ovate, brown, some- 

 what pellucid, lightly striate, scarcely shining; whorls 4y 2 

 to 5, convex, the last more than half the total length; spire 

 short, convex, apex obtuse ; aperture semioval, auriform, pro- 

 vided with a parietal fold ; peristome thickened, reflexed, the 

 outer margin strongly sinuated, columellar margin widely 

 reflexed. Length 2, diam. iy 2 mm. Distinguished from the 

 last [P. iivulifera] by its shorter and more ovate figure.

Shell minute, rimate, whitish, ovate-cylindroid ; whorls 5, 

 convex, sculptured with delicate growth-lines, separated by a 

 slightly oblique suture, the last whorl someAvhat varicose be- 

 hind the lip. Aperture small, five-toothed; a strong, double 

 columellar tooth, a smaller one, also bifid, on the parietal wall, 

 two small ones remote from the right margin, and a fifth 

 minute basal tooth. Peristome narrowly expanded, white, the 

 margins joined by a thin callous. Length 2,y 3 , diam. l 1 /^ mm.

This species is a trifle less cylindrical than P. pellucida Pfr., 

 a Cuban species; but it has the number of teeth and their 

 arrangement similar. The columellar tooth, however, is 

 double, the upper portion of it being most prominent; the 

 tooth above it, upon the body-whorl, is single, bifurcating at 

 the end. The three remaining teeth are rather remote from
