its base, which also presents three or four minute spinules along 
its inner or median margin, does not project beyond the distal 
end of the penultimate joint, whereas in C. carnifex it reaches 
to the middle of the terminal joint. The penultimate joint is 
armed with a minute spinule at the outer angle of its distal end. 
The two basal joints are very hairy, and the flagella are rather 
short, being scarcely as long as the cephalothorax. 
The legs are similar to those of C. equabilis, var. merguiensis, 
and probably resemble still more those of C. carnifex. The 
anterior legs are equal and quite similar to those of C. equabilis, 
var. merguiensis, even as regards the distribution of the spinules 
_ with which the chelipedes are armed, and hairs with which they 
are covered. In C. carnifex the upper margin of the hands is 
prominent, like a crest, and armed with four or five acute spi- 
nules. In this species such a crest 1s not found; the hands are 
scarcely more than twice as long as broad, the inner margin of 
the upper surface of the palm is not at all prominent, and armed 
with three or four spinules which are not larger than those of 
the rest of the upper surface of the palm. The legs of the 
second pair are similar to those of C. equabilis, var. merguiensis, 
and probably still more resemble those of C. carnifex, Heller. 
These legs have a completely smooth surface, presenting no other 
punctations than those in which the short hairs are implanted, 
and which are rather thinly distributed. The propodite of the 
left leg of the third pair is a little shorter than that of the 
right, and a little depressed on its outer surface ; this outer sur- 
face still appears, however, slightly convex. In C. equabilis, 
var. merguiensis, the outer surface of this propodite is much more 
depressed ; so that it appears perfectly flattened, and the upper 
margin of the outer surface is subacute. The dactylopodites 
finally are comparatively longer than those of C. equabilis, var. 
merguiensis, and are scarcely as much compressed ; they termi- 
nate, as in this species, in curved, black, pointed tips, and are 
armed, on their under margins, with a row of seven or eight 
acute spinules. As I have already observed, the legs of the 
second and of the third pairs are thinly clothed with short, stiff 
hairs arranged in small tufts; those of the fourth pair, on 
the contrary, are densely clothed with much longer hairs along 
their margins ; and those of the fifth are, again, less hairy. . As 
regards the two or three spinules with which the meropodites are
