sentations of his description. I was not aware until lately that this 

 shell had already been described, but my English characters of the 

 species may not be unacceptable, as they are more minute. 



6. Cypr^a sulcata (Grooved Cowry). Cyp. testd ovato-globosd, 



ventricosd, albd ; bast rotundatd, aperturd latiusculd, postice in- 



curvd, canalibus profundis et latis ; dentibus cequalibus, labii ex~ 



terni circa triginta, lateri^ columellaris viginti, supra columellam 



continuis marginem internam serratam formantibus ; costellis 



prominentibus plerumque ad impressionem dorsalem terminantibus , 



pseudo-costellis ad utramque extremitatem circa decern ; sulco 



columellari lato, profunda, margine externa prominente, acuto ; 



extremitatibus obtusis^ crassis ; spird conspicud ; impressione 



dorsali conspicud. 



Shell globoso- ovate, ventricose ; entirely of a clear white colour ; 



base convex, aperture rather wide, curved inwards at the posterior 



end, channels deep and broad ; teeth numerous and even, about 



thirty on the lip and twenty on the columellar side, which traverse 



the columellar groove to terminate at an inner serrated edge ; the 



ribs are continuations of the teeth, are prominent, and almost all 



terminate at the dorsal impression, a few only on the sides of the 



shell ; false ribs at each end about ten, interstices between the ribs 



minutely striated longitudinally ; columellar sulcus broad and deep, 



the outer edge, sharp and prominent, occupies the anterior third of 



the length of the columella, the other portion of the inner part of the 



columella flat (not grooved) ; extremities obtuse, thick, those of the 



lip longer than the body of the shell, the posterior one in a marked 



degree, which, passing round to form the channel, ends somewhat 



abruptly in a prominent sharp edge on the columella, which sharp 



edge constitutes the inner extremity ; spire perceptible, the false ribs 



pass over it ; dorsal impression well-pronounced, extends the length 



of the back to the false ribs at each end ; margins none. 



It is nearest in general form to Cyp. formosa of Gaskoin, but 

 diiFers from it in having a dorsal impression, much coarser ribs, in the 

 sharp outer edge of the columellar sulcus, the peculiar position and 

 form of the inner and projection of the outer posterior extremities, 

 in its pure white colour, &c. 

 Hab. Manilla.

7. Cypr^a vitrea (Glass-like Cowry). Cyp. testd ovato-globosd, 

 albd, nitidd, semivitred ; basi rotundatd, aperturd angustiori paulu- 

 liim incurvd, marginibus crassis ; dentibus cequalibus, numerosis, 

 prominentibus Jabii externi circa triginta, columellaris viginti supra 

 sulcum columellarem continuis ; sulco columellari lato, Icngitudinem 

 aperturce (cquante, margine interne subrecto, serrato; costis magnis, 

 (Bqualibus, prominentibus , cum dentibus continuis ad dorsum ter- 

 minantibus; lined dorsali impressd ; extremitatibus obtusis, crassis 

 brevibus ; margine externo crasso ; spird inconspicud.
