PLATE LXVIII.

Fossil Crustacea.

Figs. 1, & 3. "Fossil Crabs, from Sheppey."—Mr. Parkinson. The London clay of this celebrated locality contains an abundance of the fossil remains of Crustacea; and the visitor may purchase of the local collectors fossil crabs and lobsters, as readily as the recent species from the neighbouring sea. Good specimens are however rare, and command high prices. The specimens figured are two common species.

Fig. 1. Cancer Leachii, of MM. Desmarest and Brongniart.

Fig. 3. Inachus Lamarckii.

These fossils show the usual mode in which the crustaceæ occur in the hardened clay of Sheppey. The thorax is bent over the abdomen, and the pair of large chelate claws drawn towards each other.
