The stylocerite spine of the antennular peduncle is strong 
and extended beyond the first joint, the second and third 
joints are subequal in length, the upper flagellum is short, 
about equal in length to the second and third joints of the 
peduncle together, the whole scarcely half the length of the 
antennal scale; the lower flagellum is very slender, and a 
little longer than the upper. 
The antennal scale is long, reaching about three-fourths 
the length of the rostrum, rigid, narrow, tapering, the exter- 
nal spine on the second joint of the peduncle is not very 
acute, the remainder of the peduncle is only about one-sixth 
the length of the scale, the flagellum is nearly as long as the 
body of the animal. 
The third maxillipeds are very robust, reaching a little 
further than the anterior angle of the carapace, the terminal 
joint is very broad at the end, and is provided with 11-13 
strong, but short, teeth, six or seven of which are on the 
inner margin. 
The first pair of pereiopods are scarcely different from 
those of the preceding species, except that the propodus is 
not so swollen above at the proximal end, and the joints are 
comparatively a little longer. à 
The second pereiopods are long, slender, and reach forward 
a little beyond the maxillipeds. The merus is a little shorter 
than the carpus, the first and third carpal divisions are sub- 
equal. The ischium of this joint is marked with two small 
spines, which are close together and on the inner side. 
In the third, fourth, and fifth pairs the carpal joints aud 
the dactyli are longer than in the preceding species. 
The pleon is moderately geniculate at the third segment. 
The first segment is the shortest, the third more than twice 
as long as the first, the second and fifth are subequal in 
length, and the fourth a little longer, the sixth is not much 
longer than ihe fifth, the pleura of the segments are very 
deeply produced, almost covering the peduncles of the pleo- 
pods in the females; their posterior angles are scarcely 
rounded or abrupt, the posterior oblique margin of the fifth 
is without spine, and is produced much deeper than the 
sixth segment, the postero-lateral margin of the sixth seg- 
ment has a large lobe, :tipped with a small spine projecting 
over the base of the telson. 
The telson is longer than the sixth segment of the pleon, 
it narrows quickly, tapering to end in four spines, the two 
inner ones longer. Тһе uropods are longer than the telson, 
the outer ramus is well thickened on the external margin. 
Length, excluding rostrum and telson, 38 mm. 
Length of carapace, 13 mm. 
Length oı rostrum, 16 mm.
