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

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

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



6. CYPRiEA sulcata (Grooved Cowry). Cyp. testd ovato-globosd, 

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

 curvd, canalibus profundis et latis ; denlibus cequalibus, labii ex- 

 terni circa triginta, lateris 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, pro/undo, margine externo 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 

 differs 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.

7. Cypilea vitrea (Glass-like Cowry). Cyp. testd ovato-globosd, 

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

 liim incurvd, marginibus crassis ; dentibus cequalibus, numerosis, 

 pr ominentibus, labii externi circa triginta, columellaris viginti supra 

 sulcum columellarem continuis ; sulco columellari lato, lengitudinem 

 apertures cequante, margine interno subrecto, serrato; costis magnis, 

 cequalibus, prominentibus, cum dentibus continuis ad dorsum ter- 

 minantibus; lined dorsali impressd; extremitatibus obtusis, crassis 

 hrevibus ; margine externo crasso ; spird inconspicud.
