STALK-EYED CRUSTACEA. 



merus is granulated on its outer face, spinulose on the upper edge, and 

 grooved near the articulation with the carpus; the carpus is granulated on 

 its outer side and furnished with a median internal tooth; the propodus is 

 inflated, granular along the superior margin and at the proximal end of 

 the outer face where some of the granules are enlarged, and tubercular on 

 the larger claw; the rest of the outer surface of the propodus is smooth 

 in adult specimens. The meri of the ambulatory limbs are spinulose on 

 their upper edges.

Carapace broad, convex in the antero-posterior direction, granulated, 

 especially on the hepatic, branchial, and cardiac regions ; areolations well 

 marked and protuberant. Front divided by a small median incision into two 

 slightly convex lobes whose edges are simple and not produced into teeth at 

 the lateral angles. Antero-lateral margin cut into five teeth j postocular 

 tooth small, separated from the second tooth by a shallow granulated sinus ; 

 the third tooth is the broadest, and rounded off at the apex; the fourth 

 is the most salient, and acute; the fifth is very small and acute; all 

 the teeth have crenate or else spinulose margins. The margin of the 

 orbit is minutely crenulate ; its upper part is marked by two closed 

 fissures ; the external hiatus of the orbit has the form of a triangular 

 notch ; the lower margin is produced to form an obtuse tooth at the inner 



The subhepatic region is granulous, but not provided with a tub- 

 ercle. The merus of the third pair of maxillipeds is also granulated. The 



angle. 



carpus of the chelipeds is rough with small tubercles, grooved along the 

 distal margin of the outer side, and armed internally with a small blunt
