LAMELLIBRAN CHIATA. 
343 
C. Loveni, Thompson. 
Shell of a somewhat rounded outline, with about thirty ribs, set with 
small scales ; height and length equal ; colour pure white. Length 3£ 
lines ; breadth 3f ; very thin and delicate ; ribs rounded, about thirty in 
number, and becoming beautifully fine towards the beak ; covered with 
minute closely-set transverse scales throughout, but which are more nu- 
merous on the ribs at each side ; furrows about the middle of the valve 
smooth and shining, narrower than at the sides, where towards the base 
they are crossed by transverse scales, and towards the apex punctate ; 
near the beaks they appear in the form of a mere linear depression. 
Colour pure white, with somewhat of a pearly lustre inside and outside. 
Compared with the British species of Cardium, this comes nearest C. 
edule, but is more handsome in form, sculpture, and colour. It is more 
rounded (less truncate at the anterior end), has the beaks terminating in 
a finer point, ribs more numerous and with the scales on them more closely 
set, but less elevated, the furrows narrower. 
Cardium scabrum, Philippi. Enum. Moll. Siciliee, vol. ii. p. 38, pi. 14. fig. 
16, comes so near my shell, that future investigation may possibly show 
that they should be brought together ; C. scabrum differs from it in hav- 
ing only twenty-six ribs, in the furrows being equal and punctate, and in 
its exhibiting two obscure violet rays, and having the beaks yellow ; but 
as my specimens were not seen in a living state, stress need not be laid on 
the difference of colour. This species was obtained in three localities 
nearly about the same time. In October, 1841, numbers of it, but mostly 
broken, were found by Dr. Earran in the stomachs of sole ( Solea vulgaris ) 
and plaice ( Platessa vulgaris) purchased in Dublin market, and taken off 
the eastern coast ; in June, 1842, Mr. Hyndman dredged a few specimens 
from a depth of 50 fathoms, off the South Rock, coast of Down ; and spe- 
cimens which I have seen in Mr. Cuming’s unequalled collection were 
sent him by Dr. Loven, 1842, as a species unknown to him, and which 
had been obtained on the west coast of Sweden. It is named in honour 
of this distinguished naturalist. 
Among some minute shells, dredged in 1846 in or near Bantry Bay 
by Mr. M‘Andrew and kindly given to me, is one of this species. I saw 
specimens of Dr. Farran’s from Birterbuy Bay. 
Should C. scabrum prove identical, in four localities — from Sweden to 
Sicily — this has been subsequent to the publication of Philippi’s first vol. 
in 1836 ; and the species is for the first time described in his second vol., 
which appeared in 1844. 
Mr. Hanley informs me that Philippi considers C. nodosum, Mont., 
this species. 
C. Icevigatum, Linn. 
“ Portmarnock, Bantry Bay,” Turt. Dredged off Glenarm, in Belfast 
and Strangford Loughs, sparingly, Mr. Hyndman and W. T. Clew Bav, 
1840. 
Birterbuy Bay, single valves dredged from 18 to 20 fathoms, hard sand, 
Dr. Earran. South Isles of Arran, Mr. Barlee. 
In Bantry Bay it seems to be in greater numbers than ordinary.
