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 ischium-joint. The first joint of the sternum, which borders 
the buccal cavity posteriorly, is granular in both sexes; in the 
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 the male the second joint of 
the sternum, lying between the bases of the anterior legs, is 
minutely granular anteriorly, the granules becoming gradually 
smaller and finally disappearing towards the posterior half, which 
is smooth; the lateral margins of this joint present somewhat 
larger granules. The third joint is granulated along its anterior 
and lateral margins, but is smooth in the middle; the two 
following joints are nearly completely granular. Those portions 
of the carapace which he between the joints of the sternum and 
the bases of the legs are also coarsely granular. 
The lateral margins of the 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 the 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 the upper surface. In the Mergui specimens the hand is 
about as long as the 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. The 
fingers are minutely punctate on their outer and inner sur- 
faces, and their sharp, thin, inner edges are faintly denticulated,
