CANCROIDEA. 185 



characteristic. The posterior outline of the deflexed portion is nearly 

 straight, except either side, and is neatly set with rounded granules ; 

 and there are a few short transverse rows of such granules on areolets 

 1 M, 2 M, and some other parts. The posterior legs are quite hairy. 

 The inner margin of the arm is fringed with hairs, and the flattened 

 surface under the sides of the carapax is covered with short hairs, as 

 well as the under surface of the body, against which it rubs in its 

 motions. The interval in the orbital margin filled by a process from 

 the base of the outer antennae is rather broad. The margin of the 

 front inside of the antennas (the outer of the inter-antennary lobes of 

 the front), projects horizontally considerably beyond the insertion of 

 the moveable part of these antennae. 



The specimen, an alcoholic one, has a pale brown colour, and the 

 fingers are also brown, showing that they were not originally black.

The Feejee specimen measured five and one-fourth inches in great- 

 est breadth of carapax, and three and one-eighth inches in length of 

 same. The colour was a maroon brown; of fingers, chestnut brown, 

 excepting tips, which were white. Eight posterior legs with both 

 margins densely pilose in one or two ranges, the hairs deep red; tarsi 

 with shorter tufts also on the sides, claw of tarsus black. Abdomen 

 of male seven-jointed, last segment half shorter than penult. Antero- 

 lateral margin of carapax nine-toothed, one of these the post-orbital. 

 The fourth and fifth, and seventh and eighth, smaller than the inter- 

 mediate.
