THE SPIDER CRABS OF AMERICA 65 



stiff, distant hairs; merus armed with some small spines; fingers in 

 contact throughout their length. Ambulatory legs cylindrical, 

 smooth, first and second of equal length, third and fourth a little 

 shorter; all have the dactylus and part of the propodus thinly fringed 

 with hair. Sternum and abdomen granulate; a spine on first seg- 

 ment of abdomen; abdomen of female very wide. 



Variations. — A Porto Rican male in the National Museum differs 

 as follows from the type described above: Instead of an intestinal 

 spine there is a very low tubercle; instead of three branchial spines 

 there is only one, which is in the middle of the region ; before and be- 

 hind it there is a very low tubercle. Postorbital spine more slender 

 than in the figured type. Besides the two spines on the anterior half 

 of the basal article of the antenna, there is a third one behind the 

 eye. The carpus and the outer margin of the merus of the chelipeds 

 bear some good-sized spines; manus oval-globular, thicker than in 

 Edwards's figure 1. The chelipeds of the type male are described 

 as "faihles," but they are stout in the figure cited. The dactyl of the 

 ambulatory leg is armed below with very small, sharp spinules, visible 

 only with a strong lens.
