its vivid and elegant colourmarkings, reminding those of C. planiliratus, as figured by Sowerby, 

 I was a little misled, but its shape is exactly that of the middle-sized C. inucronatus of the 

 Siboga-materials; these specimens vary in the development of the grooves, partly in accordance 

 with age, the ventral side being mainly stronger grooved than the dorsal one. Reeve (1. c.) says : 

 "varying remarkably in their general appearance; most of them are obsoletely coronated, and 

 all have the grooves more or less developed". If more materials were present and 

 the differences proved to be constant, this form might be described as a good species.

The variability of this well-known species, as far as concerns the sharpness of the spiral 

 ridges, confirms my views on the var. Sibogae of the former species.

Unfortunately the shell is quite bleached. As it is of interest to be certain about its 

 identification, as much controversy has arisen about its true habitat, East-Indian or West-Indian, 

 I asked the opinion of Mr. E. A. Smith, who thinks I may be right; if this be so, the authors 

 who doubt its East-Indian provenience, may not have possessed the true species (Weinkauff, Tryon).
