nally, bearing four or five spines, the two apical ones being 
rather divergent ; there is also a prominent spine on the inner 
angle, with a small spinule just below it. The acicle is robust, 
regularly tapering to end in two spines, with one just below 
them on the outer or upper side, and one on the inner side, 
near the base ; the acicle reaches rather more than half the 
length of the fifth joint. The third joint is produced below 
to a strong spine, which reaches nearly as far as the fourth 
joint. The fourth joint has a small spinule above at the distal 
end. The fifth joint reaches about as far as the middle of the 
ultimate joint of the antennular peduncle. The flagellum is 
shorter than the carapace, and hairy. 
The chelipeds are equal, and weak. The merus reaches 
to about the level of the acicle of the antennae ; it bears a few 
spines on the upper margin, near the distal end, and a few 
on the other two margins; the external surface is slightly 
rugose. The anterior surfaces of the carpus and palm are 
densely hairy — the hairs hiding the spines — flattened and 
covered witu spiniform tubercles, mostly curved forwards, and 
many with acute, dark tips ; these are larger on the inner 
margins. Tne palm is shorter than the carpus ; it is not 
swollen behind, as in the preceding species. The fingers are 
longer than the palm, spinulose, corneous at their tips, and ex- 
ternally marked at their opposable edges with small, rather 
regular teeth. There is no hiatus. 
The second and third pairs of legs are nearly similar, the 
third pair being slightly longer ; they exceed the chelipeds in 
length by about half the length of the dactyli in the second 
pair. The meri are slightly rugose externally. The carpi 
are externally sulcate, as also are the propodi, and with them 
bear on their anterior margins spines similar to those on the 
chelipeds, which, however, are smaller and less numerous on 
the third pair. The propodi also are slightly squamose. The 
dactyli are about as long as the propodi : thev are faintlv sul- 
cate and spinulate on their anterior and posterior edges, 
are slightly curved, and end in dark claws. 
The fourth pair is short, non-chelate, the carpus and 
propodus nearly equal in length, the propodus distallv nar- 
rowing. The dactylus is short, robust, and spinulate. 
The first two pairs of abdominal appendages in the male 
are well developed : the single pair of the first segment in the 
female is weak. The other appendages are of the usual char- 
acter. 
The telson is four-lobed, the two anterior lobes larger 
than the posterior: the posterior lobes are unequal, rounded 
behind, and spinulate and setose on the margins.
