clama (Herbst), to which species are doubtfully referred specimens from West Australia 
(3 to 5 fathoms), in the collection of the British Museum, and which is apparently 
distinguished by the evenly granulated and narrower and more elongated carapace. 1

An adult male was obtained in the Torres Straits, August 1874. 
It belongs to what is regarded as the typical condition of this very variable species, 
having but a single accessory spinule on each of the cornese of the rostrum (Crust. H.M.S. 
“ Alert,” p. 197).

This example, as the measurements show (although adult) is not of very large size. 
The chelipedes are not so greatly developed as in very large males, and the dactyli are 
much less strongly arcuated.

Micippinx, Miers, Journ. Binn. Soc. Bond. (Zool.), vol. xiv. p. 660, 1879. 
Carapace somewhat oblong-oval or sub-oblong. Rostrum vertically or nearly 
vertically deflexed ; usually broad, lamellate. Chelipedes with the fingers acute at the

collection the fingers are distally acute, and scarcely, if at all, excavated.
