THE ORAPSOID CRABS OF AMERICA. 127 



Ivegs of neailv equal length and of moderate width, sharply mar- 

 gined above, and punctate and hairy; merus joints a little dilated at 

 middle ; propodus slightly tapering distally ; dactyls of all legs simi- 

 lar, curved, upper part flattened and ending in a slender, curved 

 spine; below there is a laminar expansion which is in a plane oblique 

 to the upper surface and terminates in a shorter spine and is 

 bordered posteriorly bj' 7 slender spinules. 



The abdcmen covers the sternum, its segments are all separate, the 

 seventh is half as wide as the sixth, beyond which it projects 

 abruptly with an arcuate margin. 



Male. — The tooth at the lateral angle and the ridge leading from 

 it are more prominent in the male than in the female. The chelae 

 are stouter in proportion to their length. The abdomen tapers regu- 

 larly to the distal end ; the terminal segment is semicircular. 



Color. — A female (50168) has the legs banded with brown; in legs 

 1 to 3 one band covers the proximal half or two-thirds of the merus, 

 another band occupies the major part of the propodus; on leg 4 the 

 color occupies less than half the merus and the distal third of the 

 dactylus. There are three transverse stripes of brown on the proxi- 

 mal third of the abdomen. 



Measu7'ements. — Female (holotype), length of carapace 4.8, width 

 of same 6.4 mm. Female (50168), length of carapace 5.5, width of 

 same 7.3 nini. Male (50168), length of carapace 4.6, width of same 

 5.7 mm.

Ischium of extei-nal maxillipeds usually distinct from merus, 

 though smaller and sometimes imperfectly united with it. Merus 

 longitudinal or little oblique. Palpus of good size, sometimes as 

 large as merus-ischium. Carapace transverse, usually broadly so.
