12 GENUSBUCCINUM. 



slightly angular whirls, the two or three lowest, crowned with 

 a row of elongated, solid, pointed tubercles, pretty near to each 

 other ; the tubercles of the upper whirls are less apparent. 

 The aperture is yellowish, ovate ; base pretty strongly emar- 

 ginated ; lip thin, arched, marked internally by two transverse 

 brown bands, which are very apparent externally. 



Length 1 inch 6 lines. Width 8 lines. 

 Inhabits the coasts of Newfoundland. 3 



This pretty species is very remarkable for the tubercles or 

 spines which project from the whirls of the spire, and which

 blance to the preceding in its form, but it is easily distinguished 

 by its different size, the BUCCINUM moniliferum being much 

 smaller.

Shell ovate, smooth, ventricose, spire formed of six slightly 

 convex whirls ; the lowest very large, slightly canaliculated ; 

 the coloring is of a deep violet and oftentimes of a yellowish ash 

 color, with a small white band which borders the base of each 

 whirl of the spire. There exists also at the base of the shell, 

 a large band of a grayish white color ; upon some specimens 

 longitudinal whitish lines are seen, which are the vestiges of 

 the several additions to the shell. Aperture large and ovular. 

 The columella is strongly arched, and upon all its length is 



3 Specimens of both the cochlidium and moniliferum are in my cabinet, 

 found at Rio Janeiro, and I cannot but think the above locality is erro- 

 neous. TR.
