BIVALVIA. » 145 
This Kelsey Hill shell has, like the shells of that deposit in general, a very recent 
aspect, appearing to have retained much of its animal matter. There are vestiges of a 
finely crenulated margin which it once possessed, but the specimen has been slightly 
waterworn. I have not met with it from any older deposit in East Anglia, although the 
name of Venus gallina is in the list of shells from Harwich by Mr. Webster before 
spoken of. As this reference of Mr. Webster’s has so long remained unconfirmed 
he possibly mistook for the present species some specimens of V. imbricata.

The smaller figure represents a perfect specimen (now in the Brit. Mus.) obtained by 
Mr. Charlesworth from Waldringfield; this is located in a mass of indurated clay. The 
larger specimen, fig. 1 a, was found by myself at Walton, and, I think, belongs to the same 
species, but the outer surface is gone, either by decortication or abrasion, so that I am not 
able to tell from its form whether it belongs to this species or to decussatus. I have also 
found an imperfect specimen in the Cor. Crag (almost a facsimile of the specimen figured 
1 a) with the exterior surface removed. ‘The hinges of either this species or of virgineus 
(or probably of both) are abundant in the Middle Glacial sand of Billockby and Hopton.

Locality. Fluvio-marine Crag, Bramerton. 
This species is, I am informed, abundant near Norwich, but I have not seen it 
from either the Coralline or the Red Crag. It is, therefore, one of the two or three 
species occurring in the Fluvio-marine Crag that, having regard to the conditions of the 
Red Crag deposit, we should have expected to have occurred also in that Crag, on the 
assumption of its being coeval with the Fluvio-marine.
