THE SPIDER CRABS OF AMERICA 



443 



Front more triangular than in cristuUpes; the space between the 

 horns is a narrow slit. Upper margin of orbit with two slight emargi- 

 nations. Outer margin of basal article of antenna subentire and 

 nondentate, although posteriorly it curves outward slightly in a 

 shallow lobe. Second free article short and stout, less than twice as 

 long as its greatest or distal width. 



Inner distal angle of merus of maxilliped deeply notched. 



Chelipeds less rough than in cristuUpes. The tubercle at the 

 proximal end of the palm is higher up or nearer the middle. The 

 fingers of the well-developed male, while similar to those of cristu- 

 Upes are a little less slender, and taper gradually from base to tip; 

 in cristuUpes they are of more even 

 width throughout. The ambulatory 

 legs are stouter than in cristuUpes, 

 especially the propodus; this article 

 has a lobe on the posterior surface as 

 well as on top ; the dactylus is shorter, 

 stouter and more curved than in the 

 allied species.
