inner margins. The inner margin of the merus-joint is a 

 little longer than that of the ischium-joint ; the exognath is 

 considerably enlarged, being broader than the anterior margin of 

 the iscbium-joint. The first joint of the sternum, which borders 

 the buccal cavity posteriorly, is granular in botb sexes ; in tbe 

 male the anterior granules are, however, a little larger than the 

 posterior, but in the female this joint is shorter and uniformly 

 covered with large granules. In tbe male the second joint of 

 the sternum, lying between tbe bases of the anterior legs, is 

 minutely granular anteriorly, tbe granules becoming gradually 

 smaller and finally disappearing towards the posterior balf, wbicb 

 is smootb; the lateral margins of tbis joint present somewbat 

 larger granules. The tbird joint is granulated along its anterior 

 and lateral margins, but is smooth in tbe middle ; tbe two 

 following joints are nearly completely granular. Those portions 

 of the carapace which lie between the joints of the sternum and 

 the bases of the legs are also coarsely granular. 



Tbe lateral margins of tbe cavity which includes the abdomen 

 are granular. The small portion of the sternum of the female 

 that is not covered by the abdomen is also granular. In the 

 male abdomen the joints are united, except the last or the last 

 two ; it is smooth, though minutely and sparsely punctate, and 

 is granulated at its base. In the large typical specimen of 

 Fabricius the penultimate joint of the male abdomen is armed 

 with a small tubercle on the middle of its anterior half. The 

 basal joints of the abdomen of the female are granulated in the 

 same way as in the male. 



The anterior legs, as in tbe adult male specimen of Fabricius, 

 are about twice as long as the cephalothorax. The arms are 

 cylindrical, and are completely covered round their bases with 

 rather small granules, which pass gradually into minute granules 

 on the distal half of the arm, only visible by means of a lens. 

 The carpopodites are minutely granular along the inner margin 

 of tbe upper surface. In the Mergui specimens the band is 

 about as long as tbe arm, and the fingers are nearly as long 

 as the palm ; the palm is scarcely more than once and a half 

 as long as broad. The immobile finger is scarcely deflexed. 

 The palm is smooth, though appearing minutely granular on its 

 inner margin, when examined under a magnifying-glass. Tbe 

 fingers are minutely punctate on their outer and inner sur- 

 faces, and their sharp, thin, inner edges are faintly denticulated,
