hairy, the palm of the larger hand and the propodites of the 
legs of the second and third pairs being almost wholly glabrous, 
their tubercles and spines being not piliferous. The outer 
surface of the larger hand and also of its fingers are covered 
in the Mergui specimen (the hands of the typical specimen are 
missing) with more numerous, though much smaller granules 
than in D. merguiensis. As regards the upper surface of 
the cephalothorax, both species almost wholly agree with one 
another, for in D. miles, as in D. merguiensis, the part which lies 
before the cervical suture is also covered with transverse, pili- 
ferous, elevated lines, of which the anterior ones are minutely 
spinulose. In the same manner the anterior margin is armed 
with minute spinules, and similar spinules are found on the 
lateral margins and at the external angles. The two lateral pro- 
minences on the anterior margin are, however, a little less promi- 
nent than in D. merguiensis. The part of the upper surface 
behind the cervicai suture is covered with hairs. 
The acute rostrum extends quite to the middle of the distance 
between the anterior margin of the cephalothorax and the 
rounded ends of the eye-peduncles; it is about twice as long as 
the inner margin of the ophthalmic scales, and it exceeds by 
its anterior third the inner margin of the antepenultimate joint 
of the peduncle of the external antenne. The basal half of the 
rostrum (between the ophthalmic scales) presents some minute 
spinules, and the free terminal half is armed on each side with 
three somewhat larger spinules, whereas the rostrum terminates 
anteriorly in two spinules. The ophthalmic scales nearly 
agree with those of D. merguiensis, but they are comparatively - 
much smaller in proportion to the breadth of the cephalothorax. 
The external antenne are somewhat hairy; the basal or first 
joint projects as far forward as the triangular teeth on the 
anterior margin of the carapace, and it is armed at the external 
angle of its minutely spinulose anterior margin with a small 
spine. The second or antepenultimate joint perfectly resembles 
that of D. merguiensis, being armed with a spinule at the outer 
angle of the anterior margin. The two spines in which the 
basal scale of the upper surface of the following or penul- 
timate joint terminates are shorter than in D. merguiensis, the 
external spine scarcely projecting beyond the distal end of the 
joint, whereas the internal spine only reaches to its middle. 
The external spine is armed at its inner margin with about five
