88 STALK-EYED CRUSTACEA. 



reo-ion take on a spiny character. The rostrum is nearly horizontal, triangu- 

 lar in cross-section, the margins serrate ; the anterior border of the carapace 

 is convex between the eyes and the antenna^ but has no spine at this point ; 

 lateral border four-toothed, one of the teeth lying at the antero-lateral angle, 

 two on the hepatic region, and one on the edge of the branchial region 

 behind the cervical suture ; the posterior border is delicately festooned, but 

 not armed with spines. The abdomen is spineless, its surface punctate, an- 

 terior half of the pleurce of the second segment tuberculate, all the pleurse 

 rounded. The eye has a transverse granulated tubercle running over the 

 cornea from the inner side. The antennae are very slender and do not 

 exceed the carapace in length. The chelipeds are moderately robust, the 

 merus tuberculate and armed with a row of short spines along the upper 

 edge ; the carpus spino-tuberculate, with two longitudinal furrows on the 

 outer side ; hand almost smooth on the inner side, outer side and superior 

 surface rougliened with low tubercles ;- fingers curved slightly upward, spoon- 

 shaped at the denticulate and setose tips. Ambulatory appendages : meri 

 flattened, tuberculate, upper edge produced to a spinose carina; the carpi 

 have three denticulate ridges; propodites scabrous, with an irregidar row of 

 spines on under side ; the dactyli have black tips and are finely spinulose on 

 their posterior edges.

The carapace of this species is moderately convex, with a deep trans- 

 verse depression across the anterior part of the cardiac area. The rostrum 

 is long, slightly upturned, and armed near the middle with a pair of lateral 

 spines. The gastric area has three pairs of spines, the anterior pair the 

 largest. There is one spine on each anterior branchial lobe. The cardiac 

 area bears two or three pairs of spines. The lateral margins of the carapace 

 carry from six to eight spines each, and there is a longitudinal series of small 

 spines within the margin on the branchial area. A small spine is situated 

 on the anterior margin between the eye and the antenna. The posterior
