The animal is very hairy, especially on the chelipeds ; th& 
hairs are plumose or pinnate. 
The carapace anterior to the cervical groove is medianly 
smooth, except for a few scattered pits ; towards the sides, 
however, it becomes rough and irregularly furrowed. There 
is a rather deep depression behind the rostral tooth, and the 
portion of the carapace immediately behind this dips into it 
rather abruptly. In this region there are a few slight, ir- 
regular furrows, which appear as branching from a median, 
shallow groove, which extends from the frontal depression for 
a short distance behind. The lateral portions of the frontal 
depression are marked on each side by a short, oblique ruga 
(more ])ronounced than in the preceding species), and the 
hepatic regions, which are full and sparingly pitted, are marK;ed 
off from the rest of the carapace by irregular longitudinal 
grooves, which join the cervical groove behind. The rostral 
tooth is triangular, acute, slightly depressed, reaching nearly 
as far as the ophthalmic scales. The front between the two 
antennal projections is strongly thickened ; these do not pro- 
ject as far as the rostral tooth, and each is tipped with a small 
denticle. 
The abdomen is of the usual soft nature, the dorsal sur- 
face of its sixth segment is strongly calcified, and divided by 
a transverse groove into two unequal parts ; the anterior por- 
tion is marked with three irregular pits, the posterior by a 
median sulcus, which is not so deep as the transverse one, 
and a few small pits. 
The ocular 2:)eduncles are long and slender, scarcely ex- 
panding distally from about the middle ; they are a little 
shorter than the widest part of the carapace anterior to the 
cervical groove. The ophthalmic scales are small, well sepa- 
rated, and each is tipped with three spinules, one of which is 
small. 
The antennular peduncle reaches nearly as far as the eyes. 
The upper flagellum slightly exceeds the ultimate peduncular 
joint in length. 
The first joint of the antennal peduncle bears 
externally two spinules. The upper surface of wie 
second joint is slightly excavated : it is much produced exter-
