rected projection. These projections increase posteriorly, 
one after the other, in size, to the 2nd abdominal segment, 
exhibiting a linguiform and, at the extremity, rounded form. 
On the 3rd and 4th abdominal segments, these projections 
are somewhat smaller and more triangular-acute. On either 
side of the body occur, moreover, 2, a trifle less prominent, 
or obtuser, carinse, the lower of which is formed by the 
inferior margin of the thoracic segment that adjoins the 
epimera. The keels rise at each segment into a knob-shaped, 
or, farther back, more dentiform projection, also observed 
on the lateral plates of the 3 anterior abdominal segments. 
The upper lateral carina constitutes, like the lower, at 
each thoracic segment, a knob-shaped projection. On each 
of the 3 anterior abdominal segments occur, in a line with 
these carina;, 3 somewhat irregular-grouped protuberances. 
The 3 anterior pairs of epimera are quite small and 
sharply pointed below. The 4th and 5th pairs are exceed- 
ingly large, jutting out prominently at the sides, as also 
bent in divers directions. The 4th pair arc furnished along 
the medial line with a sharp keel, and run out anteriorly 
as a large, downward-curving, falciform projection; the 
5th pair are somewhat smaller, triangular in shape, and 
terminate posteriorly in a sharp-pointed, mucroniform pro- 
jection. The 2 succeeding pairs are much smaller and 
of a rounded form, hut furnished in the middle with a 
knob-shaped prominence. 
The lower posterior corners on the lateral plates of 
the 3 anterior abdominal segments are shortly acute. 
The eyes are distinctly developed, rounded in form, 
prominently convex, and in colour a brilliant Vermillion. 
The 1st pair of antenna; are about one-third as long 
as the body. The peduncle is quite short, with the 1st joint 
considerably longer than the other two taken together. 
The flagellum is exceedingly flexible, rapidly tapering, and 
composed of numerous short, bristle -beset articulations. 
Secondary flagellum entirely wanting. 
The 2nd pair of antenna; are somewhat longer than 
the 1st, and have the flagellum similar in appearance. 
The 2 anterior pairs of legs are small and feeble, 
with tin; hand narrow and obliquely truncate at the ex- 
tremity. . .. 
The remaining pairs of legs are comparatively fragile, 
and provided with short tufts of bristles. The 1st pair 
are somewhat shorter than the 2 preceding pairs, and have 
the basal joint a trifle more dilated ; on all three, how- 
ever, this articulation is comparatively slender, and exhibits 
along the medial line an obtuse carina. 
The last pair of caudal stylets have the trunk quite 
short, whereas both branches are exceedingly elongate and 
somewhat lamelliform. 
The telson is comparatively short, with the point 
emarginate in the middle. 
Colour a magnificent coral-red, a trifle more vivid 
on the posterior margin of each segment.
