_E. testa maculis fuscis seu purpureis tessellatis fasciata; sutura vix canaliculata; anfractuum marginibus convexis._ Shell with bands of tessellated brown or purple spots; suture slightly channelled; margin of the volutions convex.

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. * * * * * Pl. 146 [Illustration] EBURNA Pacifica, _South Sea Eburna._ * * * * * GENERIC CHARACTER.--See Pl. 144. * * * * * SPECIFIC CHARACTER. _E. testa ventricosa, maculis fulvis fasciisque albis ornata; spirae angustae, acutae, suturis integris._ Shell ventricose, with fulvous spots and white bands; spire slender, acute; suture entire.

Mrs. Mawe informs me she has received this, along with other shells, from the Pacific Ocean. A species at once distinguished by the entire suture and narrow-pointed spire; the inner lip is very thick, with a longitudinal sulcation near the umbilicus.
