60 PROCEEDINGS OF THE ACADEMY OF 



several dark brown bands, generally 2 on each whorl ; body whorl angulated : 

 with one band directly upon the sharp angle, another in close proximity, and 

 a third quite distant and near the base of the shell. Band obsolete on the first 

 two or three whorls. Surface coarsely striate and obscurely ribbed. 



Melania glans, Anthony, being preocupied, I propose to change the name 

 to M. glandula. 



M. assimilis, Anthony. Shell small, short, conic, not thick; spire acute, 

 composed of about 7 flat whorls ; sutures very distinct, of a light horn color; 

 aperture small, ovate, dusky within ; columella indented ; body whorl angu- 

 lated ; sinus not broad, but well formed.

Obs. A small delicate species ; compared with M. pallidula, nob., it is more 

 slender and elevated, has a greater number of whorls, and is devoid of bands. 

 From M. angulata, nob., it differs in being more slender, more carinate, and 

 haring a more elevated spire. 



M. cubicoides, Anthony. Shell ovate, smooth, thick; whorls 6 1, flat, the 

 upper ones rapidly enlarging to the body whorl, which is broad, and acutely 

 angulated ; sutures distinct, rendered more so by a sharp carination on the 

 lower part of each whorl; aperture broadly ovate, within whitish ; columella 

 deeply indented ; sinus small. 



Hab. Wabash River, Indiana. My Cabinet. 



Obs. One of the short, thick species, in form not unlike M. cuspidala, nob., 

 but differing by its sharp carinated body whorl and imbricated spire ; the body 

 whorl is also strongly striate and obscurely ribbed; these longitudinal ribs are 

 very faint, but sufficiently distinct, at the sharp carina near the summit of the 

 aperture to modify its outline into a waving subnodulous line. 



M. hybrida Anthony. Shell conical, elevated, nearly smooth, horn colored; 

 whorls 8 9, upper ones carinated deeply, lower ones entirely smooth ; color 

 reddish brown, or dark horn color ; sutures distinctly impressed ; aperture 

 small, ovate, tinged with rose color or violet within ; columella rounded but 

 not deeply indented ; sinus small.

Obs. A neat, pretty species, with no very strong distinctive characters ; 

 from intertezta, nobis, which it somewhat resembles ; it may be distinguished 

 by its less acute form, less numerous whorls, and by its want of reticulated sur- 

 face so peculiar to that species. Bears some resemblance, to M. bella, Con., 

 but differs in form of outline and aperture, and has no beaded line ; is also 

 more elevated than M. bella. 



M. versipellis, Anthony. Shell small, ovate, folded, rather thin ; spire not 

 elevated, but acute, composed of about 7 flat whorls ; whorls of the spire all 

 more or less folded, penult and body whorl smooth : body whorl bulbous, sub- 

 angulated, concentrically striate ; color olivaceous, ornamented with dark 

 brown bands, of which four are on the body whorl and one only on the spiral 

 ones, located upon or near the shoulder of each volution : aperture elliptical, 

 about half the length of the shell, banded within.

Obs. A small and somewhat variable species as to coloration, though very 

 constant in other characters; it is sometimes very dark both as to bands and 

 general color, and often very light with bands scarcely distinguishable and 

 many varieties between ; it seems not to be a very common species. 



M. cognata, Anthony. Shell ovate, short, smooth, moderately thick ; spire 

 obtusely elevated, consisting of 56 convex whorls ; color brownish-yellow 

 with three dark brown bands about the middle of the body whorl, and one 

 very obscure one at the suture ; suture deeply impressed ; aperture broad-
