Shell small, ohloni:, N//V///J//// elevated, carinated, the side-si* 

 straight, steep. End valves and lateral areas pink, central areas 

 yellowish . dorsal ridge pink with an olive-green stripe on each side. 

 Sometimes olivaceous, or olive and rose. 



The lateral areas are strongly raised and sculptured with 4 or ."> 

 radiating ribs which are regularly cut into low beads, and which 

 often split toward the lower margin. Central areas having a narrow 

 smooth space upon the ridge, sculptured on each side with about 16 

 strong longitudinal ribs, separated by deep intervals ; posterior mar- 

 gins of valves crenulated. Anterior valve having about 22 granose 

 radiating ribs ; posterior valve having about 16 granose radiating 

 ribs, the umbo slightly in front of the middle, the slope behind it a 

 little concave. Interior whitish; sinus rather deep and narrow. 



Girdle covered with compactly imbricating, convex, shining obso- 

 letely striated small scales (pi. 36, fig. 6.)

Allied, in its acutely elevated contour, to C.,/".'/"*"^, but differing 

 maikedly in the granose-ribbed lateral areas. It is usually very 

 brilliantly colored with rose-pink and buff) but olivaceous torn i- 

 occur. The latter may be distinguished from C. *uit'lairi by the 

 differently sculptured central areas. Professor Hutton (in lift.) 

 suggests to me the identity of stangcri and inm'iiljtt'i*. The latter 

 seems to agree altogether with (Buoy's oanaKcMlatut. 



The girdle-scales (pi. 36, fig. 6) are smaller than in ('. jiignsus, 

 and they are much less distinctly striated than in ('. ,s///"
