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. Cyrr#a sutcata (Grooved Cowry). Cyp. testd ovato-globosd, 
ventricosd, albd ; basi rotundatd, apertura latiusculd, postice in- 
curvd, canalibus profundis et latis ; dentibus equalibus, labii ex- 
terni circa triginta, laterts columellaris viginti, supra columellam 
continuis marginem internam serratam formantibus ;  costellis 
prominentibus plerumque ad impressionem dorsalem terminantibus, 
pseudo-costellis ad utramque extremitatem circa decem; sulco 
columellari lato, profundo, 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. Cyprma virrea (Glass-like Cowry). Cyp. testa ovato-globosd, 
albd, nitidd, semivitred ; basi rotundatd, apertura angustiori paulu- 
lim incurvd, marginibus crassis ; dentibus equalibus, numerosis, 
prominentibus, labii externi circa triginta, columellaris viginti supra 
sulcum columellarem continuis ; sulco columellari lato, lengitudinem 
aperture equante, margine interno subrecto, serrato; costis magnis, 
equalibus, prominentibus, cum dentibus continuis ad dorsum ter- 
minantibus; lined dorsali impressd ; extremitatibus obtusis, crassis 
brevibus ; margine externo crasso ; spird inconspicud.
