STALK-EYED CRUSTACEA. 



specially prominent on each ridge. Fourth abdominal segment : armed 

 with but one small median spinule. The sides of the carapace below the 

 epimeral sutures are covered with spiny tubercles, and display an iridescent 

 lustre. The eye has two spines projecting over the cornea from the inner 

 side ; the posterior of these spines is very minute. The antennse are very 

 slender, and about as long as the carapace ; the first and second joints are 

 provided with a prominent external spine^ the third joint with three spines, 

 viz. one external, one internal, and one superior. The chelipeds are absent 

 in both the specimens. The ambulatory appendages are spinulosc on all 

 the segments except the dactyli, which are finely serrate on the hind margin. 

 The legs, and more especially the sternvnn, are iridescent, like mother-of- 

 pearl. This iridescence is seen in a less degree in several other species 

 of this genus.

The whole surface is clothed with long seta;, which are longest and 

 densest on the chelipeds and ambulatory appendages. The rostrum is 

 very broad at the base, and ends in three points, the middle of which is 

 the longest; the rostrum is slightly carinate in the median fine. The cara- 

 pace is roughened by low setiferous ridges \ the antero-lateral angles are 

 obliquely truncate ; a spine over the antenna, and four on the lateral mar- 

 gin, the last one just behind the posterior branch of the cervical suture, the 

 third one obsolescent ; hind margin unarmed. A pair of spines on the gastric 

 region behind the base of the rostrum. The abdomen is devoid of spines, 

 and there is no spine over the eye. The antenna) are slender, shorter than 

 the body ; the basal joint is provided with a long spine on the external side, 

 and another on the internal side ; the second joint has an external spine, the 

 third an internal one. Chelipeds ; internal edge of merus fivc-spincd, su- 

 perior edge also furnished with a row of smaller spines; carpus with one 

 prominent internal spine ; hand unarmed, broadest at base of fingers, cutting
