The whorls of this species, which is not punctured like the Delphi- 
nula Peronii, are encircled with solid rings about seven to the whorl, 
after the manner of a Scalaria; the shell might indeed be mistaken 
for one, were it not for its solidity and pearly interior.

This species differs from the Delphinula Peronii in having the spire 
more prominent, and varices entirely across the whorls; they are also 
more strongly and closely set ; the shell is moreover much more spa- 
ringly punctured. 
3. Detpuinuts pepressa. Delph. testd plano-rotundatd ; spird 
valde depressd, foraminibus puncturatd ; albd ; anfractibus superne 
angulatis, fortiter varicosis, varicibus ad angulum acuminato- 
elevatis ; intus margaritaced.

No one can fail to recognize this species, by its depressed spire 
and by the pointed elevation of the varices on the angle of the whorls. 
4. Detrninuta piscomEA. Delph, testd discoided; spird plano- 
depressd, liris longitudinalibus et transversis, interstitiis subtiliter 
striatis, eximié clathratd; peripherid carinis duabus clathratis 
prominentibus ornatd.

The latticed sculpture of this shell very much resembles the cha- 
racter of a figure in plate 31 of the ‘ Magasin de Zoologie’ for 1834, 
under the appellation of Delphinula adamantina, Ducios. It differs, 
however, essentially from that species in form, and I regret to say 
the D. adamantina, according to the figure alluded to, is quite un- 
known to me, though elaborately described by Deshayes in the ninth 
volume of his edition of Lamarck’s ‘ Animaux sans vertébres.’ 
5. De.pninuna Evotuta. Delph. testd spiraliter discoided, partim 
evolutd ; anfractibus subquadratis, marginibus corrugato-crenatis.

The loose manner in which this shell is rolled, giving it the ap- 
pearance of a miniature hunter’s-horn, is not a casual deformity. 
Several specimens were collected by Mr. Cuming at the above- 
mentioned island.
