CRUSTACEA OF THE MERGUI ARCHIPELAGO. 259 
times bears another much shorter spinule at its base, which, 
however, is often indistinct. The upper surface of the wrist is 
covered with two rows of hairs, and some hairs are also found on 
its under surface. The hands are a little distorted, but otherwise 
seem to resemble those of Gebiopsis nitida. They are as broad at 
their proximal halves as the meropodites, and the fingers are much 
shorter than the palm, being only halfas long. The palm, rounded 
above and below, is smooth and unarmed, but clothed with hairs, 
some of which are arranged in longitudinal, often oblique, rows. 
The equally long fingers cross one another with their pointed tips 
when closed ; the mobile finger is strongly curved, very hairy, and 
armed at the base of its inner margin with a small tooth, whereas 
the immobile finger is nearly glabrous and minutely denticulate 
along its inner margin. 
The second legs resemble those of G. nitida; the meropodites, 
which are much narrower than those of the chelipedes, are fringed 
with long hairs along their inferior margins ; the propodites area 
little longer than the carpopodites, and nearly three times as long 
as the dactylopodites, which are therefore apparently shorter 
than those of G. nitida, but about the same size as those of 
G. Darwinii. The upper margin of each carpopodite and pro- 
podite, and also the under margin of the latter, is fringed with 
long hairs, similar to those of the inferior margin of the meropo- 
dites ; each dactylopodite is also hairy. 
The meropodites of the third pair of legs are, again, narrower 
than those of the second pair (in the species from the Cape Verde 
Islands, on the contrary, they are figured as being broader) and 
nearly glabrous, being not fringed with long hairs; the carpo- 
podites of these legs are a little longer than the propodites and 
somewhat hairy at their distal ends. The outer surfaces of the 
compressed propodites are covered with two dense rows of hairs ; 
and each of these joints is, moreover, clothed with a dense tuft of 
hairs at the distal end of their under margin, and with a few hairs 
along its upper margin. The hairy dactylopodites are a little 
more than half as long as the propodites. The equally compressed 
propodites of the fourth pair of legs are a little shorter than the 
earpopodites and scarcely longer than the dactylopodites; and 
the outer surface of each is also covered with two dense rows of 
hairs, as on the propodites of the third pair, and a similar dense tuft 
of hairs is found at the distal end of the under margin of each.
