_E. Arcolata_, _Lam. Syst._ 7. _p._ 282. 4.

A sh.e.l.l hitherto placed as a variety of _E. spirata_, (_Buccinum spiratum_, Lin.) 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 sh.e.l.ls 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 sh.e.l.l can be found; for those given by the authors above named, are almost too inaccurate for citation. It inhabits the Indian Ocean.
