REPORT ON THE BRACHYURA.

and usually (but not invariably) distinctly lobulated in its anterior half. The front is 
somewhat deflexed, with its anterior margin sinuated and usually with a small median 
notch. The antero-lateral margins are not cristated, and are divided into rounded lobes 
(not teeth), of which only the three posterior are usually distinct. The orbits are 
small, and the fissures of their upper margins very slightly marked, the interior subocular 
angle is not produced. The post-abdomen of the male is usually five-jointed, with the 
three intermediate segments coalescent and forming a single joint. The eyes are set on 
short thick pedicels. The basal antennal joint is somewhat elongated, and produced 
along the exterior margin of the infero -lateral frontal process so as to enter partly within 
the interior orbital hiatus. The merus of the exterior maxillipedes is usually transverse 
and distally truncated. The chelipedes, in the male, are subequal and moderately 
developed, with the palms rounded, not carinated above, and the fingers excavated 
at the distal extremity. The ambulatory legs are of moderate length, with the joints 
(except the dactyli) slightly compressed, but not carinated ; the dactyli styliform and 
straight. 
The species of Carpilodes are small, and rather numerous, and, with one doubtful 
exception, occur in the Oriental region ; but the range of two or three species extends 
eastwards to the West American coasts. None, I believe, have been ascertained to occur 
in deep water. 
The following species are probably referable to this genus, as I have characterised 
it above, besides the species enumerated by A. Milne Edwards in 1865. They were 
either referred by him to Actsea and to Liomera , or have been described since that 
date : — 
Carpilodes cinctimanus (Adams and White). Indo-Pacific Region, eastwards to 
the west coast of North America. 
? Carpilodes longimanus (A. Milne Edwards) = Cancer nigerrimus, Desbonne and 
Schramm. West Indies. 
Carpilodes monticulosus, A. Milne Edwards. New Caledonia. 
Carpilodes margaritatus, A. Milne Edwards. New Caledonia. 
Carpilodes edwardsii, Kossmann. Red Sea. 
Carpilodes granulosus , Haswell. Torres Strait. 
Carpilodes bellus (Dana). Samoa Islands ; Paumotu ; Philippines. 
? Carpilodes .dia (White) =Actseodes cavipes, Dana(?). Philippines; Polynesian 
Islands. In this species the basal antennal joint enters the interior orbital 
hiatus as in the typical Carpilodes, but the species is distinguished by the 
peculiar lunate crests of the ambulatory legs. It should, perhaps, be separated 
as a distinct genus.
