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 xxiii, 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 

 sulcated; 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 sulcated" char-
