Prof. Forbes’ original specimen, with the aperture exposed from the cover- 
ing rock, has been represented on Plate XXVIII, Fig. 29. This specimen is in 
a beautiful state of preservation; it is apparently perfectly convolute, like an 
Ovula, but the inner lip is in its entire length toothed, the denticles being short ~ 
and almost obsolete towards the anterior termination. The denticulation of the 
outer lip is only internally visible, being extremely fine. The surface is covered 
with very minute spiral strie. The entire character of this species is exactly the 
same as that of the recent Cyp. Adansoniana, which is also externally convolute 
and spirally striated. It would be very interesting to break up a specimen of 
this rare species or to observe young specimens so as to ascertain whether the 
shell is really convolute or involute in the first stage. In either case I think it 
very probable that a new sub-genus must be formed for these shells, unless they 
can be referred to Troschel’s Hrronea, though it must first be known how to 
restrict or characterize this last one. 
3. Cyprma (Luponta) Newsoup1, Forbes, p. 54. 
The dentition of the lips is beautifully clear on Forbes’ original, the teeth 
become considerably smaller on the posterior half of the inner lip, than is usually 
the case in species of Luponia. 
4. Cyprama (LUPONTA) cARNATICA, Stoliczka, Pl. IV, Fig. 4, 
1865. Cyp. Cunliffei, Forbes, antea, p, 55, non idem, Forbes. 
This species having been previously by me incorrectly identified with Forbes’ 
Cyp. Cunliffei must now receive a new name. 
6. Cyprma Kayet, Forbes, p. 56. 
Forbes’ original specimen of this species is a little more globose than most of 
ours, but the distinction does not appear to be a specific one. The dentition is 
distinctly traceable on both margins. 
The Cyprea bullaria, Schlotheim, of which I received authentic specimens 
through Prof. Geinitz, is still more globose than the present species, having on 
the casts the spire usually impressed and very narrow, but it comes close to our 
Fig. 7 of Plate IV. 
OCyp. spirata, Schloth., also from Faxoé, is quite distinct from the former, 
having the spire rather elevated and the aperture posteriorly strongly produced ;
