CRUSTACEA OF THE MERGUI ARCHIPELAGO. 249 
Dana, is minutely denticulate along its whole length, is quite 
entire in these specimens. The wrist is armed with an acute 
spine at the distal end of the inner margin of the upper surface ; 
the latter is somewhat uneven, and clothed with some yellow 
hairs. The hands perfectly resemble those of C. equabilis, C. 
corallinus, and C. zebra, as regards their form and size; their 
upper surface is nearly twice as long as broad (the fingers in- 
cluded), and the palm is considerably swollen below. The inner 
margin of the upper surface of the palm is armed with a row of 
four or five acute teeth, and the upper surface is covered with 
some more or less acute tubercles or teeth. These tubercles are 
more numerous and more acute on the fingers, which have spoon- 
like excavated tips, and are armed with two or three rather 
strong teeth along their inner edges. The convex under surface 
of the hands is rather smooth. The hands and the fingers are 
rather hairy above and a little so below. 
The legs of the second and of the third pairs have a smooth, 
never granular, surface, which, however, presents many small 
impressions, in which the hairs with which the legs are clothed 
are implanted. The meropodites of these legs are armed with 
one or two acute spinules at the distal ends of the inferior 
margins of their outer surfaces; the carpopodites present a 
similar acute spinule at the distal ends of their upper margins. 
The propodites are unarmed ; those of the legs of the second pair 
and those of the right leg of the third pair have the usual cylin- 
drical form, their outer surfaces being rather convex; the pro- 
podite of the left leg of the third pair, on the contrary, has a 
somewhat trihedrous form, its outer surface being remarkably 
flattened, so that the upper margin is rather acute. If Dana’s 
figure, 4.f, of this joint is exact, then these specimens somewhat 
differ from the Madeira type: in the latter this joint is rather 
slender, the outer surface being a little more than three times as 
long as high, and with nearly straight margins; whilst in the 
Mergui specimens the outer surface is only a little more than 
twice as long as high and is bordered by a slightly arcuate 
upper margin. The dactylopodites are compressed, with some- 
what convex outer and inner surfaces, except the dactylopodite 
of the left leg of the third pair, the outer surface of which is 
flattened or even slightly concave. The dactylopodites of these 
two pairs of legs are all shorter than the propodites, measuring
