The sides of the l)r;UKlii;il I'ci^ioiis hclow tlu; sj)iii('s ;irc ci>iicav(i, 

 sniuotli, sliiniiiif, aiul clothed with (•(unote, udjjrcsscd, microscopic 

 hairs. The posterior border is iicute ajid minutely tuljerculate. 



Basal joint of outer antenna terminating^ in two spines : tlu; 

 outer is directed upwards and outwards ; its apex is in a line 

 with and projects slightly beyond the front of the (ubit ; the 

 outer margin and the a))ex superioi'l}' are tuljerculated. inner 

 spine short, triangular, dir(>cted forwards and outwards. 



Chelipedes in adult inale of moderate size, equal in length to 

 the carapace and rostral spines ; merus joint as long as the upper 

 border of the hand, beset with tubercles similar to those occurring 

 on the carapace, the larger of which are seriate ; three form a 

 longitudinal row on the inferior surface ; another row of three 

 occurs on the inner proximal portion of the upper border, and 

 there are two or more in a line with a blunt median spine, situated 

 at the distal extremity. 



Carpus obtusely angulate, a little shorter than the mobile 

 finger ; outer and upper surfaces with numerous small tubercles ; 

 a large spiniform tubercle marks the junction of the angles 

 proximally. 



Hand measured along the lower surface twice as long as deep, 

 tumid and rounded below, narrow and somewhat angular in the 

 proximal half above ; surface minutely granulose, and more or 

 less clothed with distant, adpressed, microscopic hairs. Fingers 

 with lines of pits on their lateral surfaces ; inner edges acute and 

 minutely denticulate distally, proximally each has a slight lobe ; 

 the lobe on the mobile finger is a little in advance of and is 

 adapted to a depression anterior to that on the lower ; there is a 

 slight hiatus at the base when the fingers are closed. 



Ambulatory legs elongate, slender, decreasing in size posteriorly; 

 the anterior ai^e about twice as long as the carapace is bi-oad. 

 Merus joint rounded, perceptibly increasing in diameter in the 

 distal half, abouc as long as the carpus and propodus combined. 



Carpus depressed and slightly grooved both above and below, 

 nearly twice as wide distally as proximally. 



Propodus cylindric, twice as long as the carpus. 



Tarsus curved, compressed, about one-tenth shorter than the 

 preceding joint. 



Joints of all the legs more or less covered with minute, adpressed 

 hairs ; fourth, fifth and sixth with tufts of hooked setfe along 

 their upper borders ; the seventh bears numerous short stiff setse, 

 which are confined to the borders ; the lateral surfaces are glabrous 

 and longitudinally grooved. 



The female differs from the male in having smaller and more 

 slender chelipedes ; the hand is much less tumid, and three times
