second joint bears a long stout and curved spine ; the end joint is narrow, 
de ae longer than broad, and furnished with a few terminal sete 
ei 0); 
The second maxillipeds are moderately stout and elongated ; they are 
also apparently three-jointed, and bear a number of plumose sete, as 
shown in the drawing (fig. 11). 
All the thoracic feet, both in the male and female, are wert and 
moderately stout, and the general structure of the first three pairs is 
somewhat similar in the two sexes, though they differ somewhat in the 
armature and in one or two other minor details. 
In the first pair the inner branches are composed of two and the 
outer of three joints; there is not much difference in the length of the 
two branches. The second joint of the inner branch is rather longer 
than the first, while the middle joint of the outer branch is much 
smaller than either the first or the third joints. Both branches are 
similarly armed in the two sexes. The outer are furnished with several 
stout spines on the exterior margin and apex, and with a short plumose 
sete on the inner margin. The inner branches are provided with a 
number of plumose sete, especially on the inner edge, but those on the 
inner branches of the female are more elongated. There is also a stout 
sigmoid spine on the inner aspect of the second basal: joint in the female 
first pair, which appears to be wanting in that of the male. (See figs. 
12 and 13.) 
The second pair in both sexes have the inner and outer branches 
three-jointed. In that of the female the inner branch is rather shorter 
than the outer; the first joint bears one sete, the second two, and the 
third two on the inner margin; the third joint has also three apical setz 
and another on the middle of the outer margin. All these sete are 
elongated and plumose. The outer branch has the proximal joint 
moderately stout and as long as the next two joints taken together: it 
bears a single seta on the inner edge and a short spine on the outer distal 
angle; the second joint, which is smaller than the first or third, also 
bears a short marginal spine, while the third joint has two spines on the 
outer margin and two at the apex. 
In the male the length of the outer and inner branches of the second 
pair is about the same ; the armature of the inner margin of the inner 
branch is similar to that of the second pair in the female, but the end joint 
bears two terminal spines instead of sete, with another spine on its 
outer margin ; the armature of the outer branch in the male does not 
differ much from that of the same branch in the female, except that the 
marginal spines are rather longer. (See figs. 14 and 15.) 
The third pair, as in the second just described, have in the two sexes 
both branches three-jointed. In the male the third pair scarcely differs 
from the second either in structure or armature. In the female the third 
pair is rather smaller than the second, but the inner branch carries the 
same number of plumose sete, while the outer branch, though armed 
with the same number of marginal spines as that of the second, wants 
the seta on the inner rrargin of the first joint (fig. 16). 
The. fourth pair in the female is almost the same in structure and 
armature as the third pair; but in the male the fourth pair is very small, 
and though the outer branch consists of three joints, the inner is only 
two-jointed and distinctly shorter than the outer; both branches are 
provided with moderately stout spines (fig. 17). 
The fifth pair consists of a narrow, elongated, one-jointed branch, 
which is articulated to a rudimentary basal joint and furnished with two 
slender apical spines (fig. 18). The female represented by the drawing 
(fig. 1) is about 4°5 millimetres in length.
