Wales and Van Diemen’s Land;’ at all events it is not figured in 
Reeve’s monograph of the genus. Itis larger than C.eximia. Iam 
not perfectly clear that it will prove to be the same; if so, it will 
corroborate an opinion which I have some time held, that the 
C eximia was not a fossil, but carried inland by the aborigines, and 
fell from near the surface to the position in which it was said to be 
found.— Vide pp. 296, 297.” 
On CyYpPpREA UMBILICATA AND C. EXIMIA OF SOWERBY. By 
J. EK. Gray, Esa. 
[Proe. Zool. Soc. Lond., 13th November, 1849.] 
Cyprea umbilicata was described from a single specimen which 
was formerly in the Tankerville Collection, and is now in the British 
Museum. From its external resemblance to some specimens of 
Cyprea Pantherina, some peculiarities in its formation, and especially 
from certain apparent irregularities in its teeth, it has been thought 
that it might be a monstrosity, or irregular growth of that species. 
The discovery of the habitat by Mr. Gunn, who has kindly sent 
two specimens of the species to Europe, has removed this impression, 
and shown that it is a distinct species; and that what was regarded 
as the irregularities in the plaits of the front of the pillar, is in fact 
the normal form of the species. 
Such being the case shows that the species should be removed 
from the genus Cyprea, as restricted in my monograph in the Zoo- 
logical Journal, and placed in the genus Cyprovula, first described 
in that work. 
The shell, instead of having the single large plait in front of the 
inner lip separated from other plaits by a wide space, has the front 
of the inner lip covered with several oblique plaits, nearly up to 
the front edge of the notch. 
It also agrees with Cyprovula in the spire being concave or 
sunken, forming a deep umbilicus. 
Cyprea eximia, figured in Strzelecki’s ‘New South Wales and 
Van Diemen’s Land,’ is a very nearly allied species, and equally a 
Cyprovula (eximia). It differs in the body being more globular and 
the canal longer. Both these species are to be distinguished from 
the other Cyprovule by the canal at each end of the mouths being 
more developed and produced: they also both have a somewhat 
angular depression across the upper part of the anterior canal, at the 
anterior extremity of the dorsal line, evidently formed by the 
junction of the two expansions of the mantle in this part. 
The elongation of the canals, and the depression above referred 
to, are more developed in Cyprovula eximia than in Cyprovula 
umbilicata. They are, especially the latter, the giants of the genus. 
The original specimen of C. eximia is in the cabinet of Mr. John 
Morris of Kensington. 
To give some idea of the extraordinary price which is now some-
