Shell ovato- globose, almost round, of an uniform, semivitreous, 

 shining', white appearance; base convex, aperture rather narrow, 

 slightly curved inwards its whole length, edges thick ; teeth even, 

 rather thick, prominent, about thirty on the lip and twenty on the 

 columellar side, where they traverse the columellar groove and ser- 

 rate its nearly straight inner edge ; the groove is broad and very 

 shallow, and nearly equal in width and depth the whole length of 

 the aperture ; the teeth continue to form the ribs, which are large, 

 even and prominent, and terminate at the dorsal impression, with 

 the exception of two or three on each side ; the false ribs all form 

 denticulations ; dorsal line impressed, extending from the apices 

 formed by the joining of the false ribs ; extremities obtuse, thick and 

 short ; margin very thick, none on the inner side ; spire not per- 

 ceptible in the adult shell, being thickly covered by the false ribs.

Differs from Cypraa glohosa of Gray in the anterior extremities 

 being of an equal length, aperture much narrower and less curved, 

 base rounder, its semivitreous shining appearance, &c.

 Shell ovato- globose, shining, of a clear snow-white colour ; base 

 round, being a continued convexity with the body of the shell, there 

 being no margin on either side ; aperture widest at its anterior half, 

 rather wide generally ; the columellar side spiral, edge of the lip but 

 very slightly so ; columellar groove extends the entire length of the 

 columella, and is continuous at both ends with the channels ; it is 

 broad and deep, particularly at the anterior half; its outer and inner 

 edges spiral, the outer edge angular and somewhat projecting; 

 teeth very minute, numerous and even, about forty-eight on the lip, 

 and about thirty-four on the columellar side, which traverse the co- 

 lumellar groove to notch its inner edge ; the ribs delicate and even, 

 and are continuations from the teeth ; many terminate on the sides of 

 the shell (the teeth being so numerous, the outer portion could not 

 contain their prolongation), the rest end mostly in fine points at the 

 dorsal impression, alternately from either side ; a few are united 

 with those of the opposite side ; interstices between the ribs finely 

 crenulated longitudinally ; dorsal line impressed ; extremities, the 

 anterior very slightly, the posterior much produced ; spire prominent 

 and tinged with a light yellow colour ; margins none. 



This shell differs from the Cypraa vitrea, just described, in the 

 minuteness and number of the teeth and delicacy of the ribs ; in the
