196 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
is dentate, extends transversely a little more outward than the 
equally long posterior portion, and is somewhat compressed ; 
both portions are parallel to one another. The antero-lateral 
portion being twice emarginate, two teeth are observed behind 
the obtuse external orbital angle; these teeth have the same 
size and shape as the extraorbital tooth, being obtuse and 
rounded. A small tubercle lies nearly on the middle of each 
postero-lateral region. The pterygostomian regions are reticu- 
lated as in Sesarma. The third joint of the outer foot-jaws 
is oval, being scarcely longer than broad. The terminal somite 
of the abdomen of the female is only partially pushed into the 
penultimate segment, at least in the specimen before me. 
Having no male individuals I cannot describe the chelipedes 
of that sex; but in the female specimen they are small and 
equal to one another. They are everywhere clothed with the 
same down as is found on the upper surface of the carapace, 
and they are quite unarmed ; the convex outer and inner surfaces 
of the hands are smooth, though rather coarsely punctate, and 
the upper margin of the palm is armed with a longitudinal crest. 
The fingers are smooth; the upper margin of the mobile finger 
is punctate, and both fingers are armed with five or six small 
teeth which terminate in pointed horny tips. 
The ambulatory legs are similar to those of C. Balanse ; they 
are unarmed, covered with a close down, and are somewhat 
hairy, but the slender, little arcuate dactylopodites are unarmed 
and scarcely hairy, and gradually taper into a very acute point.
