of secondary bristles, the pectination being rather weak on bristle no. 2, counting from the
anterior side of the limb. most powerful on no. 5. The single bristle on the anterior side of this
process is short and has short hairs. The seven bristles of the third endite (fig. 10, $ = Ç)
are powerful, especially the posterior one, and of moderate lengths; bristles nos. 4, 5 and 6.
counting from the front, are somewhat shorter than the rest. Of these seven bristles either
only the two anterior oues and the posterior one have at the middle wreaths of long, powerful
secondary bristles while the others have no such bristles or eise one may also find such wreaths
on bristles nos. 4 and 6, counting from the anterior side of the limb. Bristles nos. 1, 2 and 4
with a moderately strong pectination distally; their points are, however, smooth; bristles nos. 3
and 5 are sharply serrated distallv; nos. 6 and 7, especially the latter, are very strongly pectinated
distally; on the former one the point is, however, smooth. The ventral chitinous spine of the
protopodite is of moderate size and irregulär. E p i p o d i a 1 appendage: This has from
about 50 to 55 bristles, all with long hairs, but with smooth points. The exopodite is
five-jointed. First joint: The main tooth consiste of seven constituent teeth, all well defined
proximally; the secondary teeth of the latter vary to some extent, from a type about the same
as in C. (Doloria) levis to that of C. (V.) norvegica. On the posterior side of this joint, close to
the main tooth, there is one bristle, on the anterior side of the joint there are four, which show
a close agreement with those of C. (V.) norvegica, but of these four the next innermost one is
somewhat shorter and weaker than the one nearest to the main tooth and only weakly pectinated
distally. The second exopodite joint has four a-bristles, seven or eight b-bristles, one c-bristle
and one d-bristle. The equipment of the a- and b-bristles is passibly somewhat stronger than
in C. (V.) norvegica; the c- and d-bristles are moderatelv long and have long, fine hairs at the
middle, short, fine hairs distally. The following exopodite joints are quite of the same type
as in the last-mentioned species, with about a similar equipment of bristles. The inner lobe
of the third exopodite joint has two distal bristles and one proximo-posterior bristle, the outer
lobe has two distal ones. The fourth joint has distally on the inner edge three or four bristles,
proximally of which one or two bristles are to be found. The end joint has two distal bristles.
The equipment of the bristles is also about the same as in the species mentioned. The pilosity
is also similar in the two species.

S i X t h limb: — Pro t o p odite: The first endite has two rather long and powerful
distal bristles, furn ished with some wreaths of long, stift’ secondary bristles and two or three
rather short, plumous medial bristles (on the right side of the only specimen that was investigated
the medial bristles [two] were almost completelv reduced [pathologica!?]; they were well
developed on both limbs in the male). Second endite: This has two rather long and powerful
distal bristles, furnished at the middle with long, stift secondary bristles, distally pectinated,
and, in addition, with three rather short, plumous, medial bristles. The third endite has four
or five distal bristles, one of which is rather short, the rest rather long and powerful. subequal;
they either all have long, stift secondary bristles at the middle and short hairs distally or else
one or two of them may have only short hairs. In addition there is on this endite a rather
long medial bristle, plumous in the middle. The epipodial appendage of the
protopodite is represented by four short bristles, bare or almost so; sometimes the distal one of
