long and powerful, the middle one being somewhat longer than the two others; the.y are furnisbed
at the middle with from two to five wreaths of long, stiff secondary bristles and are rather strongly
pectinated distally. Of the two bristles in the posterior group the anterior one is generally
somewhat shorter than the posterior one in the anterior group, powerful, furnished at the middle
with a few wreaths of long, stiff secondary bristles, and very strongly pectinated distally. The
posterior bristle is considerably shorter, usually rather weakly pectinated distally and furnished
at the middle with a wreath of long, stiff secondary bristles. Of the five inner bristles on the
second endite (fig. 20), ail rather powerful and moderately long, all except the middle one have
one or more wreaths of long, stiff secondary bristles at the middle. Bristles nos. 1, 2 and 3,
counting from the anterior side of the limb, are rather strongly pectinated distally, nos. 4 and 5
are somewhat angular and very powerfully pectinated distally. The single bristle on the anterior
side of this endite is very short and weak and has short, fine hairs or is almost bare. Third
endite (fig. 21): All the seven bristles of this process are rather long, except no. 6, counting
from the anterior side of the limb, which is relatively short; no. 5 is also a good deal shorter
than the others, but not so short, however, as no. 6. Of these bristles no. 1 is furnished
proximally of the middle with one or a few wreaths of rather long, stiff secondary bristles and
bristle no. 7 also has a few such secondary bristles at the middle (sometimes they are absent
in the latter bristle; perhaps broken off?); the other bristles, on the other hånd, have no such
secondary bristles. Bristle no. 1 is rather weakly pectinated, bristles nos. 2, 3, 4 and 5 have
rather strong pectination distally; bristles nos. 6 and 7 are somewhat angular distally and very
strongly pectinated. The distal chitinous spine of the protopodite is rather long, narrow and
bent. Epipodial plate: This has about 55 bristles, all with long hairs, their points
being, however, bare. Exopodite: First joint: The main tooth (fig. 22) has seven constituent
teeth all well defined proximally, whose secondary teeth are usually of the type reproduced in
the adjoining figure. The bristle close to the main tooth on the posterior side of this joint
is rather short, with sparse, short hairs. On the anterior side of the joint, near the main tooth,
there are four rather powerful bristles, arranged in a close row, the one nearest to the main
tooth being rather long, the rest decreasing rather rapidly in length the farther towards the
outside of the joint they are situated. The two longer ones of them are rather strongly pectinated
distally, but usually have no long, stilf secondary bristles, the two shorter ones are weakly
pectinated distally and usually have a wreath of long, stiff secondary bristles at the middle.
The second joint has four a-bristles. Of these the three larger ones are of about the type that
has been reproduced in fig. 23 of C. ( Siphonostra) spinifera, very powerful and furnished with
very strong but rather few secondary teeth; the number and strength of the secondary teeth
of these bristles seem, however, to be subject to rather great variation. The smallest a-bristle,
the posterior one, is quite short and rather weak, usually bare but sometimes, however, furnished
with some relatively coarse secondary teeth. There are also seven or eight b-bristles; only in
one specimen was the latter number observed on the limb of one side; these bristles are moderately
strong and of about the type reproduced in fig.22 of C. ( Vargula) norvegica. This joint has, in addition,
one c- and one d-bristle, subequal and somewhat shorter than the longest b-bristles; the c-bristle
has short hairs, the d-bristle has long, fine hairs at the middle and short hairs distally or is almost
