 penultimate whorl. Aperture suboblique, oblong, narrowed and 

 angular above ; peristome simple, unexpanded, acute, scarcely 

 spreading, reflexed in a long triangle at the columelhi. Length 19,

This pretty species, dedicated to Mr. Paul Geret, superintendent 

 of the conchological sales-room of the Deyrolle establishment, re- 

 sembles certain Antillean species, but I know of no Brazilian species 

 which approaches it much. It resembles D. marielinus Poey, of 

 Cuba and Florida, but is larger; the ground-color of the shell is 

 white, not amber, the color of the bands is darker and their arrange- 

 ment not the same. It has also some analogy to the banded 

 variety of D. vincentinus Pfr. (Ancey*). 



D. SUCCINEA n. ep. PI. 26, fig. 38. 



Shell imperforate, ovate, excessively thin, somewhat transparent, 

 with the texture of Succinea. Pale yellow, very glossy, sculptured 

 with coarse, irregularly spaced, oblique, narrow folds. Spire short, 

 the apex obtuse, with the usual sculpture of Drymceus. Whorls 4|, 

 moderately convex, the last rather inflated, carinate in front at the 

 periphery, especially in immature specimens. Aperture oblique, 

 ovate, the outer lip thin and simple ; columellar margin thin below, 

 reflexed and adnate above. Length 14, diam. 8^ mill. 



Amazon river (Steere Exped.). 



This species differs from liwpidits Drouet, and guUula Pfr., in 

 being plicate. In contour it resembles colmeiroi Hid., but differs in 

 sculpture and color. 



D. FUNEIIALIS Bruguiere. 



Shell imperforate, similar in form and size to B. radiattis, but 

 thinner, brighter white, and marked with o black spiral bands on 

 the last whorl, the two lower wide, middle one narrow, the others
