in life, and the legs are fringed with longer hairs ; the hairs on tin- 

 front edge of the merus of the chelipeds arc red and long, forming 

 a close fringe concealing the lour large spine- : there is another 

 fringe of long hairs near the lower edge. The man us has but one 

 distal spine, and a long proximal spine at the carpal articulation. 

 The rnanus lacks the subdorsal ridge proent in the other species, it- 

 place being covered by the iridescent patch ; the dorsal ridge is 

 subcarinate; its edge is obtuse and fringed with a r<>\\ of red hairs 

 on each side ; it terminates in a strong sharp spine, slightly hooked 

 inward, situated at about the distal fourth of the edge. 



The areolations of the middle of the carapace, on perfect dry speci- 

 mens, from which the pubescence has not been rubbed, form a rather 

 conspicuous and ciiriou> face-like or mask-like iigure, more notice- 

 able than in the allied specie-.

Specimens, with the carapace 32 to 38 inm long, taken April, 1901, 

 in Castle Harbor, were in life more highly colored than the smaller 

 ones. The carapace and legs were finely and elabor.-.tely variegated 

 and mottled with red, yellowish brown and gray, producing the gen- 

 eral effect of reddish brown. A small whitish spot, bordered with 

 brown, appeared behind the bases of the posterior lateral spines. 

 The under side was pale orange, pinkish around the mouth, deeper 

 orange on the chelipeds and legs ; and with some spots of orange- 

 brown on the basal segments of the abdomen. The chela?, above, 

 were deep red-brown, the fingers crossed by two light orange-red 

 bands ; the iridescent area on the outer surface reflected prismatic 

 colors, but especially green, red, and silvery tints. The iridescent
