fine hairs or are almost bare. In addition there are numerous short cleaning bristles, al
of about the same length, of two types, 22—25 of them with an extremely fine and dens(
double pectination (fig. 8; drawn as smooth in fig. 6), and a smaller number, about six or seven,
with very powerful double distal pectination (fig. 9; the spines are shown in fig. 6). On the
posterior edge this joint lias, in addition, somewhat distally of the middle, two bristles, both
of the same type, rather short, bare and spine-like, one of them situated somewhat distally of
the other. Near the posterior distal boundary of the joint there are also two smooth, straight,
spine-like bristles (fig. 10), situated at the side of each other; the lateral one of these is about as
strong as the two last-mentioned bristles, but somewhat shorter than these, the medial one is
considerably stronger and is about twice as long as the lateral one. The small end joint (fig. 10) is,
especially posteriorly, very strongly chitinized. Of its bristles the two middle ones, the main
claws, are extremely powerful, but short, being only about a fifth of the length of the second
endopodite joint, and very strongly serrated along the proximal two-thirds of their length; (for
practical reasons this serration is only drawn on one of these claws in the acljoining figure);
of these two claws the latéral one is rather considerably shorter than the médial one. The
two anterior ones, somewhat different in length from each other, are rather considerably shorter
than the middle claws, weak and quite bare. Of the three posterior bristles, all bare, two are
somewhat weaker than the two anterior ones, one of them being about as long as the longest,
the other as long as the shortest, of the main claws; the third one of these bristles is very short.
Pilosity: The first endopodite joint has short hairs dorso-distally, the second endopodite joint
has posteriorly groups of short, fine hairs placed transversally.
Maxilla (fig. 15): — Protopodite (fig. 16): First endite: The bristles on the
only specimen of this species I have had the opportunity of examining were defective; ten strong,
subequal bristles of moderate length were observed. All of them were f uni ished with rather
numerous long, sti ff secondary bristles; on the two (originally there were presumably three) inner
ones the secondary bristles continued right to the point of the bristles, on the others they
stopped a short distance from it. Of the latter three were trifurcated distally and five had
a simple strong point. Of the latter five one was smooth distally, the others were furnished with
powerful distal secondary teeth. The second endite has seven rather powerful, subequal,
moderately long bristles. All of them, except the one next to the outermost one, seem to be furnished
at the middle with long, stilf secondary bristles; the four outer ones are pectinated distally,
the three inner ones are smooth distally. The third endite has five moderately powerful distal
bristles, of which the outer one is unusually long, about twice as long as the next outer one;
the rest are moderately long, the inner one being somewhat shorter than the others. The inner
bristle has short hairs; the outer one has, along a large part of its length, rather numerous, long
and comparatively flexible secondary bristles and is extremely finely pectinated distally. The
three remaining ones of these bristles have a moderate number of long, stiff secondary bristles
at the middle, and are pectinated distally, the pectination on the inner one of them is, however,
very weak. The proximal bristle on the outside of this endite is about half the length of the
outside of the process and has short hairs. The dorsal bristle of the coxale is attached at about
