are relatively somewhat longer than in this figure. These two bristles have at the middle a few
wreaths of long, powerful secondary bristles and are bare distally; the other bristles are furnished
distally with similar secondary bristles, here too arranged more or less distinctly in wreaths.
Second endite (fig. 18): The five inner bristles are moderately long, the middle ones being
somewhat shorter than the outer ones, and powerful, the posterior one being somewhat more powerful
than the rest. On the specimen that was investigated by me all these bristles, except the
posterior one, were furnished at the middle with one or a few wreaths of long, stiff secondary
bristles; the posterior bristle has no such wreath at all or only a reduced one, represent ed by
a few short secondary bristles (see the drawing). Bristles nos. 1 and 2, counting from the front,
were almost bare distally, only furnished with a few rather weak spines; no. 3 was sharply
serrated distally; no. 4 was strongly pectinated; no. 5 was furnished near the point with rather
few very powerful secondary teeth, proxima liv of which there were some weaker ones. The
bristle on the anterior side of this process was moderately long and had short hairs. The seven
bristles of the third endite are powerful and moderately long; the proportion between thern is
about the same as is shown in fig. 21 of C. (Vargula) norvegica. Bristles nos. 1, 3, 6 and 7,
counting from the anterior side of the limb,are furnished at the middle with a wreath of long, stiff
secondary bristles, the other bristles have no such secondary bristles. Bristle no. 1 is weakly
pectinated distally; bristles nos. 2 and 4 are strongly pectinated distally; bristles nos. 3 and 5
are sharply serrated distally; bristles nos. 6 and 7 are very strongly pectinated distally. The
distal spine of the protopodite is of moderate size, fig. 19. The e p i p o d i a 1 plate has
71 to 73 bristles, all with long hairs almost right to their points. The exopodite has four
joints. First joint: The main tooth is composed of seven constituent teeth, which have about
the same equipment as is shown in fig. 22 of C. (Vargula) norvegica. On the posterior side of
this joint close to the main tooth there is a single bristle of about the same length and type as
this bristle in the figure mentioned of C. ( Vargula) norvegica. On the anterior side of this joint
there are four bristles, which have about the same position and types as in the above-mentioned
species; the third, counting from the inside, is, however,somewhat shorter relatively and has short
hairs or is almost bare; the two inner ones are perhaps somewhat more powerful. The second
joint has three a-bristles, ten b-bristles, one c-bristle and one d-bristle. The a- and b-bristles
are somewhat more powerful than the corresponding bristles in C. (Vargula) norvegica (cf. fig. 22
of this species). The c- and d-bristles (fig. 19) are about as long and strong as in the species
mentioned and of about the same type as each other, having close long and soft hairs at the
middle and short hairs distally. The third joint is very small (fig. 19), its outer lobe even
almost completely reduced. The inner lobe has four bristles distally; these are rather weak,
have short hairs or are almost bare; two of them are moderately long, subequal; one is a little
more than half as long as these, the fourth, the outer one, is quite short. Postero-proximally
this lobe has, in addition, a bristle of about the same length as the shortest of the distal ones.
The outer lobe has two bristles, one of moderate length and with short hairs and one, the outer
one, very short, almost reduced, naked or almost naked. The end joint is moderately large
and somewhat rounded; it has five moderately long bristles distally, of somewhat different
lengths. They either have only short hairs or one or a few of them bave, in addition, a moderate
