the columella. This feature Mr. Conrad describes as occurring at the bend- 
ing of the columella. On the specimens which I have seen it is distinctly 
above the bend of the columella, and in the figure given by Mr. Conrad in 
vol. 3, Pl. xxi, fig. 3, American Journal of Conchology, it is distinctly thus 
figured. In Mr. Tryon’s figure in his Structural and Systematic Conchology 
this important feature is entirely omitted, as also is the kneed character of 
the columella, the only generic feature.

“Shell pyriform; ventricose; transversely ribbed and longitudinally 
suleated; summit of the whorls flattened and subcanaliculate; right lip stri- 
ated within; channel much contracted; beak straight or slightly recurved 
at the base.” (Conrad.) 
A single individual of this species has been obtained in a recognizable 
condition, and that one of small size, while the body whorl of a second 
specimen, with the outer coating entirely removed and of about the size of 
Mr. Conrad’s type, is in the collection, but would probably not have been 
recognized as pertaining to the species had it not been for the presence of 
the smaller shell. The characters of the shells agree perfectly with the 
description given above, except that the columella has a single oblique 
fold a little above the angle, and in the top of the volution being less flat- 
tened, and the suture less channeled than one might suppose, though both 
features exist. On both of the specimens four of the spiral ridges, much 
larger and more prominent than the others, occupy the larger part of the 
body whorl, which gives a somewhat angular appearance to the volution, 
while the spaces between are occupied by very much more subdued 
ridges. The vertical ridges which give the “longitudinally suleated” char-
