summit of the inner sub-ocular lobe, its inner distal angle 

 and margin is strongly prominent and granulate, the re- 

 maining joints are small. 



The epistome is narrow in the longitudinal direction, and 

 sunken. 



The pterygostomial regions are full, marked by oblique, 

 granular ridges; above the ridges on each sub-hepatic region 

 are two large spiniform granules. 



The buccal frame narrows somewhat anteriorly, its upper 

 margin is strongly arched, and two median lobes of this mar- 

 gin are united in front, leaving a small opening or foramen 

 behind, opening on to the epistome. The sides, also, of the 

 buccal frame are slightly arcuate. 



The external maxillipeds are narrow. The ischium joints 

 are very narrow at their bases, but expand distally, the in- 

 ternal distal angles being prominent and almost touching, 

 thus a large triangular space is made between them. The 

 merus joints are oblong, shorter than the ischium, with the 

 distal fourths quickly accuminating to obtuse median apices, 

 beneath which the carpal joints are articulated, only a por- 

 tion of them being exposed. The exopod gradually narrows 

 distally, and although rather long does not attain to the 

 apex of the merus. 



The pleon of the male has the first segment evenly granu- 

 late from side to side, occupying the whole of the space 

 between the last pair of legs, the second segment is short, the 

 third, fourth, and fifth are coalesced; the second to the sixth 

 inclusive has each a medium prominence, on which a larger 

 granule is situated ; the seventh segment is small and rounded 

 at the extremity. The pleon narrows from the third segment. 



The chelipeds are short and stout, cancriform, the fingers 

 of each just meeting when folded in front, only a small por- 

 tion of the distal end of the arm is visible from above; this 

 has a thickened distal ridge on the onter side. The carpus is 

 broad, externally convex, bearing four or five granulate tuber- 

 cles. The hand is short, externally convex, bearing finer gran- 

 ules, with two granular tubercles near the upper margin; the 

 larger one near the base of the mobile finger; also a mass of 

 long hair spreads over the base of the mobile finger. The 

 fingers are rather narrow, short, the mobile one strongly curv- 

 ed, hairy above, with a few small granules, and a few small 

 teeth on its cutting edge. The immobile finger is shorter, and 

 bears a strong tooth near the end and a short sulcation on the 

 outer side. There is a small proximal hiatus between the two 

 fingers. 



The ambulatory legs are short, moderately stout, finely 

 granulate, and moderately hairy. The carpal and propodal
