BemarTcs. — This species reminds one at once of Pupa crysalis, Fer., but the 

 outline is more fusiform than it. It is nearly allied to Melania pupaformis, 

 Anth., but it is a larger and stouter shell and is not so much banded. The aper- 

 ture is narrow and unusually closed. Some specimens are feebly banded, while 

 others have the usual four bands very broad, which make the interior dark, and 

 give the exterior a dark brownish or submaculate appearance. Two of the speci- 

 mens are entirely without bands. The aperture is about one-third the length of 

 the shell.

Eemarlcs. — This species is allied to clausa, herein described, but it is more 

 conical and less cylindrical. One of the two specimens is obscurely banded, while 

 the other has well-defined bands, the broadest one being above. The aperture is 

 about one-third the length of the shell. 



Goniobasis punicea. PI. 34, fig. 27. 



Testa Isevi, subcylindracea, crassa, punicea; spira elevata, conica; suturis impressis; anfractibus con-

 ad basim rotundata. 

 Shell smooth, somewhat cylindrical, thick, reddish brown ; spire elevated, conical ; 

 sutures impressed ; whorls slightly convex; aperture small, ovately rounded, white 

 within ; outer lip acute ; columella thickened, white, rounded at the base.
