in that species. The larger hand is much narrower and more cylin- 

 drical, and the dactyli of the ambulatory legs are not so strongly 

 curved as in C. ohscurus.

Several specimens were collected at Caravellas, Province of Bahia. 

 They do not differ perceptibly from Florida specimens, except that 

 the hands are perhaps a little less tuberculose.

I refer to this species a large number of specimens collected at the 

 Reefs of the Abrolhos, 



It is certainly very closely allied to C. Braiiliensis Dana (United 

 States Exploring Expedition, Crust., p, 467, pi, 29, fig, 7), but the 

 opthalmic scales are somewhat larger than rej)resented in Dana's 

 figure, and the right leg of the third pair convex upon the outside. 

 In the alcoholic specimens the ground color of the hands and ambula- 

 tory legs is reddish-yellow, instead of olive.

A single male specimen collected at Bahia appears to belong to 

 this species. 



The carapax is broad, the breadth in front exceeding slightly the 

 length of the lateral margin, evenly convex above, the regions scarce-
