The external maxillipeds are sub-opercular ; the ischium 

 is twice as long as broad, is jDrominent at its internal distal 

 angle, and has a longitudinal sulcus; the merus is small, 

 about half as long as the ischium, sub-pentagonal in shape, 

 with granulate or spinulate margins and two longitudinal 

 sulci, with a few spinules between them ; the next three 

 joints are large, united to the merus behind its apex. The 

 exopod reaches to the external angle of the merus. 



The sub-orbital, sub-hepatic, and pterygostomial regions 

 are granulate to spinulate, the latter somewhat tumid. 



The pleon in the male is five- jointed, triangular from 

 the second segment; in the female it is six-jointed, and 

 scarcely larger, not nearly covering the dense mass of small 

 ova. 



The chelipeds in the male are long and strongly deve- 

 loped; the merus is trigonous and granulate, to spinulate 

 on the margins, especially below, on the upper border there 

 is a small tubercle near the middle ; the carpus is rounded 

 above, and indistinctly ridged with a very large internal 

 spine; the palm is much compressed, the outer surface round- 

 ed and faintly ridged, with a strong longitudinal sulcus near 

 the upper border, proximally narrowed in the vertical direc- 

 tion, it is distally expanded, and the upper border is denti- 

 culated, the internal surface is granulate and slightly exca- 

 vate. The fingers are shorter than the palm, irregularly 

 toothed, slightly ridged, and sulcated towards their tips, 

 which are brown in colour, externally granulate, and only 

 meeting at their tips. 



The ambulatory legs are slender, compressed, and not 

 as long as the chelipeds in the male. The dactyli are lon- 

 ger than the propodi, are nearly straight, and longitudinally 

 sulcate ; the propodi also have external sulci and two granu- 

 late ridges on each of their- inner surfaces.
