384 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 21 



with a lateral flange. Tip of male first pleopod elongate and pointed, 

 subterminal lobe rounded. 



Description: Compared to Teleophrys cristulipes, carapace relatively 

 longer, lateral angle more pronounced, making the carapace less rotund 

 and more triangular; the surface having more granules and fewer tuber- 

 cles and spines. Crescentic branchial elevation either side of the cardiac 

 region wider and more swollen. Only two anterolateral marginal spines, 

 one at the lateral angle and one in front of it ; this spine exceptionally 

 replaced by a tubercle. Anterior branchial spine and the hepatic spine of 

 T. cristulipes replaced by tubercles. Posterolateral spine of good size; 

 in front of it a tubercle forming a parallelogram with the three marginal 

 spines. 



Front more triangular than in Teleophrys cristulipes ; space between 

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

 nations. Outer margin of basal article of antenna subentire and nonden- 

 tate, although posteriorly curving 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 Teleophrys cristulipes. Tubercle at the 

 proximal end of the palm higher up or nearer the middle. Fingers of the 

 well-developed male, while similar to those of T. cristulipes, a little less 

 slender, and tapering gradually from base to tip ; in T. cristulipes of more 

 even width throughout. Ambulatory legs stouter than in T. cristulipes, 

 especially the propodus ; this article having a lobe on the posterior surface 

 as well as on top ; dactylus shorter, stouter and more curved than in the 

 allied species. (Rathbun, 1925, modified)
