108 PALEONTOLOGY OF NEW JEESEY. 



less likely to cause confusion. His specimens have been very much more 

 robust in the spire, which is much longer than these when perfect and 

 not so attenuated; nor do the inner volutions of this shell ever present 

 the vertical portion of the volution to view, as shown both in the original 

 and later figures given of that species. I think, however, that they are 

 generically identical, and should prefer to place them as a division of Bullia 

 rather than with Melanopsis, as was done both by Mr. Conrad and Mr. Tryon. 

 But I see no reason why they should not be included under Dr. Orbigny's 

 genus Buccinanops. 



Formation and locality: Quite a large number of the shells were obtained 

 from an artesian-well boring at Cape May, N. J., at a depth ranging from 

 320 to 350 feet from the surface. They are associated with Terebra and 

 Tritia trivittatoides, var. elongata, herein described, and are from the collections 

 at Rutgers College.

Shell small, strongly obovate, swollen or inflated above, and contracted 

 in the lower part; spire short or very obtuse, slightly coated so as to render 

 the suture indistinct; aperture narrow, not quite as long as the body of the 

 shell. Outer lip thickened outwardly and in the medial portion of its length 

 on the inside and below, but scarcely so above; strongly crenulated over 

 all the thickened parts, bearing ten distinct ridges on the only perfect 

 example seen. Inner lip bearing four distinct ridges or teeth, the lower 

 one of which is the most distinct. The surface of the shell has been pol- 

 ished when perfect. 



Dr. E. Emmons referred this species to E. Icevis from the inspection
