Extract

Having been desired by my friend Miss Caroline Birley to examine two Crustaceans in nodules from the Mekran Coast— part of a much larger series, mostly enclosing fossil shells, described by Mr. R. B. Newton, F.G.S. (see ante, pp. 293–303)—I gladly comply with the request to add a note thereon to his paper.

The first concretion, when broken open, displays the dorsal aspect in impression and counterpart of a small crab, 5½ cm. broad by 3 cm. deep, having one long, slender, forcipated chela, imperfectly preserved, measuring nearly 5 cm. in length; and part of one of the fifth posterior pair of feet, adapted for swimming, showing it to have been near to the family Portunidæ, to which our common shore-crabs of the genus Portunus belong. None of these, however, can be satisfactorily compared with the fossil crab from Ormara, which is certainly referable to another genus.
