subacute denticles. Chelipeds strongly granulated, and with a few 

 irregularly arranged small tubercles on the outer surface of the 

 manus ; lower margin double, with two rows of large granule- : 

 crest high and convexly rounded, with seven acute angular teeth, of 

 which the third is highest ; dactylus of one chela (the right in our 

 specimens) with a large, stout, downward bent tooth near the base, 

 when closed fitting into a socket between a tooth on the thumb and 

 a large obtuse tooth on the manus ; a large, Hat, rounded distal tooth 

 near the lower ed^f. 



Its colors are bright in life. The carapace is pale yellow or 

 whitish with lemon-yellow spots in irregular rows, and many small 

 bright red or crimson spots, especially laterally. Chelipeds and legs 

 bright yellow, spotted and banded with bright scarlet red ; cliche 

 with a crescent of red at the articulation of the dactylus on the 

 inside ; tips of digits and teeth of the dorsal crest of manus red ; 

 carpus with two red spots. Leg* bright yellow, with bands of red 

 and purple, and purplish red margins on the merus ; eye stalks 



orange. 



There is a close fringe of slender yellowish hairs on the dorsal 

 crest of the carpus, manus and dactylus of the chelipcds and trans- 

 verse fringes at the joints ; the mcrus lias two hairy lines forming a 

 V-shaped figure on its upper surface ; on the inner surface of the 

 manus there is a Y-shaped arrangement of long hairs, and a dense 

 distal tuft on the thumb ; the ambulatory legs have a dorsal fringe 

 of hairs and also transverse ones at the joints. The under side of 

 the carapace and the outer maxillipeds are also covered with long 

 yellow hairs.

Our form is so very similar to C. Bairdii of the Pacific coast that 

 it can hardly be separated as a species. I have been able to compare 

 it carefully with specimens from Panama and with two specimens,* 

 male and female, from Stimpson's type-locality (Cape St. Lucas, coll. 

 Xantus, Yale Mus.). The latter are, however, larger than our best 

 Bermuda specimen, which is an immature female. The Bermuda
