A SHELL hitherto placed as a variety of E. spirata, (Buc- 

 cinum spiratum, Lin.J but from which I am disposed 

 to consider it as specifically distinct. The channel or 

 sulcation round the suture of each whorl is very slight, and 

 the adjoining margin obtuse and convex ; whereas in E. 

 spirata the channel is broad and deep, having the margin 

 sharply carinated : so far the essential characters of the two 

 shells are at variance ; but their difference in colour is 

 so obvious that no one can mistake them. 



The form of the umbilicus in this species appears to be 

 constant : it is wide, deep, placed near to the upper angle of 

 the aperture, and margined externally by a convex belt. 

 With the exception of Seba's figures, (which, through the 

 carelessness of the engraver, are reversed,) not a tolerable 

 representation of this shell can be found ; for those given 

 by the authors above named, are almost too inaccurate for 

 citation. It inhabits the Indian Ocean.
