attenuated distally, with its last segment, as usual, the longest. Eyes (see 
fig. 2) not very large, and but little projecting laterally beyond the sides of 
the carapace, form nearly cylindrical, the corneal part being scarcely at all 
expanded and but very slightly emarginated on the dorsal face. Superior 
antenne with the last joint of the peduncle (fig. 3) having only a few ciliat- 
ed setze at the inner corner, male appendage (see fig. 21) fully as long as 
the peduncle. Inferior antennz (fig. 4) with the basal part rather thick, and 
forming at the outer corner only a very slight obtuse expansion, scale but 
very little exceeding the peduncle of the superior antennæ, form pronounced 
rhomboidal, the outer part in front of the exterior corner occupying nearly 
half the length of the scale, apical segment (fig. 5) very distinct and bearing 
5 of the marginal setze. Gnathopoda (see fig. 14) having at the tip 5 spines, 
the 3 outer of which are not ciliated and claw-like, the 2 inner ones ciliated 
in the middle and terminating in a setiform lash. The 2 anterior pairs of 
pereiopoda (fig. 15) having the ischial and meral joints rather expanded and 
nearly of equal length, the latter edged interiorly with several short spines 
in addition to the setze, tarsal part much shorter than the meral joint, with 
the 1st articulation rather broad and armed interiorly with several strong 
spines, dactylar joint (see fig. 16) small, with the terminal claw well defined 
from the joint and setiform. The 4 posterior pairs of pereiopoda (fig. 17) 
having the meral joint strongly incurved, forming a genicular bend with the 
ischial one, tarsal part represented by a single very short and thick articu- 
lation firmly connected with the meral joint, and having in front 4 strong 
claw-like spines disposed in pairs (see fig. 18), dactylar joint forming only 
à very minute and pellucid lobe, mostly hidden between the spines and setze 
issuing from the tarsal joint. Third pair of pleopoda in male (fig. 22) having 
the outer ramus a little longer than the inner; outer ramus of 4th pair (fig. 
23) reaching beyond the tip of the telson, outer flagellum nearly twice the 
length of the inner. Telson (fig. 20) much shorter than the last segment of 
metasome, and not nearly twice as long as it is broad at the base, outer 
part considerably tapering, lateral edges nearly straight and converging, 
being each armed with about 12 spinules, of which the 3 proximal ones 
are somewhat larger than the 4 or 5 succeeding ones, which are placed 
somewhat more apart, the outer 4 spinules on each side successively increas- 
ing in length distally, apical spines much stronger than the others, and 
having between them a very small dentiform projection, which sometimes 
is minutely bidentate at the tip (see fig. 24). Inner lamella of the uropoda 
(see fig. 19) considerably projecting beyond the telson, and moderately tume- 
fied at the base, with the otolith of middle size, inner edge armed, below 
the marginal setze, in its whole length, with about 13 spines, successively
