immobile finger carries a denticulate carina. The ambulatory limbs are of 

 moderate length, and the posterior surfaces of the meri and carpi are tuberculate, 

 while their anterior margins are strongly spinose ; the posterior surface of the 

 propodi is carinated ; the dactyli are only curved towards the apex, and their 

 posterior margins are denticulate, the teeth increasing in size towards the 

 terminal claw. 



" The eyes still retain a certain amount of mobility, and are separated 

 ventrally by from one to three small calcified pieces ; the cornea is rounded, and 

 the peduncle is prolonged into two slender lateral spines, the inner of which is 

 about twice the length of the other. The antennal flagellum is more than twice 

 the length of the body. The merus of the external maxillipeds has its inner 

 margin irregularly dentate. 



" The abdominal segments are comparatively smooth, a few granulations 

 being present merely on the posterior ones ; the second, third, and fourth each 

 bear a curved transverse sulcus, the convexity of which is directed forwards."

The carapace to the very tip of the rostrum is covered with hairy squames 

 arranged in transverse series ; its greatest breadth is about six-sevenths of its 

 length. The rostrum, the length of which is about two-fifths that of the cara- 

 pace, is broad, being at its base nearly one-third the breadth of the carapace, 

 triangular, and strongly carinated, and upcurved and serrated at tip ; the frontal 

 border is in the same convex curve with the anterior portion of the lateral borders, 

 it bears on each side a strong supra-antennal spine, and there is also a strong 

 antero-lateral spine, behind which, on the lateral border, is a still stronger spine 

 followed by two or three spinules : the posterior border is raised and quite 

 smooth ; the gastric and cardiac regions are well defined, the former having a 

 pair of spines on the middle line in front. 



The abdominal terga and pleura are squamous and hairy, but are not 

 spinate ; the second, third, and fourth terga are grooved transversely. 



The eyestalks, which are short and stout, are united with one another at 

 base and are almost immobile, each is prolonged beyond the cornea into a stout 

 spine, which projects obliquely from beneath the base of the rostrum, to which, 

 at first sight, it appears to belong. 



The basal joint of the antennulary peduncles is stout, but not inflated ; of 

 the two external terminal spines only one— the lower — is large and conspicuous.
