about fifty to sixty bristles, all vvith long liairs right out to their points. Exopodite: This
has four joints. First joint: The main tooth (fig. 22) consists of six constituent teeth, all well
defined proximally, whose secondary teeth are of about the same type as that shown in the
accompanying figure. The bristle on the posterior side of this joint, close to the main tooth,
is about as long as the anterior constituent tooth of the main tooth, is furnished at the middle
with a wreatli of long, stift’ secondary bristles and is rather strongly pectinated distally or else
almost bare. On the anterior side of this joint there are four bristles, three in a row near the
main tooth and one farther out. Of these bristles the two situated nearest to the main tooth
are rather long and subequal, the one next to the main tooth is powerful and is strongly pectinated
distally but has no long secondary bristles, the other one is somewhat weaker and has long
hairs at the middle and short ones distally. The two remaining of these bristles are somewhat
shorter than the former ones, the inner one being the shortest, and are of about the same type,
ha ving long hairs at the middle and short ones distally. The second joint (fig. 23) is furnished
with three a-bristles, five b-bristles, one c-bristle and one d-bristle. Of these the a-bristles are
very powerful and have very strong secondary teeth, the b-bristles are rather powerful; the c- and
d-bristles are of moderate length and of the same type, having long, soft hairs at the middle
and short hairs distally. The outer and inner lobes of the third joint, like the end joint, are
of moderate size. The inner lobe of the third joint has two distal bristles of moderate length,
the outer one has long hairs at the middle and short ones distally, the inner one is bare and
somewhat shorter than the outer one; in addition this lobe has a single bristle posteriorly, somewhat
more proximally, which is a little shorter than the distal ones and has long hairs at the middle
and short ones distally. The outer lobe has two distal bristles of moderate length, the outer
one being somewhat shorter than the inner one; both have long hairs at the middle and short
ones distally. The fourth joint has three distal bristles of moderate length, one with long hairs
at the middle and short ones distally, the two others with short hairs. Pilosity: The outer lobe
of the third exopodite joint is partly furnished with fine hairs.
S i X t h 1 i m b (fig. 24): — Protopodite: The first endite has one rather long
and powerful distal bristle, furnished with a few wreaths of long, stift secondary bristles, and
two short, plumous medial bristles. Second endite: This has three distal bristles, two of which
are rather long and powerful, furnished at the middle with long, stift secondary bristles and with
short hairs distally, the third, the middle one, is rather short and has long hairs at the middle.
This endite has, in addition, two medial bristles, one of which is short and plumous, while the
other, which is about as long as the long distal bristles, has long hairs at the middle and short
ones distally. Third endite: This has three distal bristles corresponding approximately to those
on the former endite, the dorsal one being, however, furnished only with short hairs; in addition
there is one medial bristle, of the same type and length as the long medial bristle on the second
endite. The epipodial appendage of the protopodite is represented by five unusually
long, bare bristles, the distal ones of which are considerably longer than the proximal ones.
Exopodite: First joint: The endite has six distal bristles and one medial bristle, of the
same types as the bristles on the preceding endite. The second joint is about twice as broad
as it is long, and has nine or ten bristles, all situated near the ventral edge; there is no pronounced
