preceding species. The exopodite is four-jointed. First joint: The main tooth lias seven
constituent teeth, all well detined proximally; the secondary teeth of the latter vary to some
extent, approaching the type reproduced for C. (Vargula) norvegica. The bristle close to the
main tooth on the posterior side of the joint is of about the same size as in C. (D.) levis and,
as in this species, has long, sti ff secondary bristles proximally of the middle; at the middle
it has a few powerful secondary teeth, distally it is smooth. On the anterior side of the joint
there are four bristles of the same type and position as in the preceding species. The second
exopodite joint has exactly the same number and position of its bristles as in the preceding
species: four a-bristles, eight b-bristles, one c- and one d-bristle; these bristles also show a
far-reaching agreement with this species in type and size, but the equipment of the a- and b-bristles
is obviously more powerful in the form dealt with here. The outer and inner lobes of the third
joint (fig. 6) are comparatively small, considerably smaller than the end joint. The inner
lobe has three bristles, two rather long and powerful distal bristles, somewhat different from
each other in length, and a very short one, situated proximally on the posterior side; all three
of them have long secondary bristles at the middle and short, fine hairs distally. The outer
lobe has two bristles, situated distally, whose type and size are about the same as those of the
distal bristles on the inner lobe of this joint; they are sometimes subequal, sometimes the outer
one is somewhat shorter than the inner one. The end joint (fig. 6) is rather large, almost square
in shape and shows traces distally and outwards of a little verruciform fifth joint. On the
latter process there are two bristles, of about the same length and type as the two bristles on
the outer lobe of the preceding joint. Besides these bristles the end joint has distally near
the medial edge three or four, usually four, bristles of which the inner ones are somewhat shorter
than the outer ones, all somewhat shorter than the two outer bristles of this joint; the outer
ones of these four are usually of the same type as the two last-mentioned bristles, the inner
ones often have short hairs. Pilosity: The outer lobe of the third exopodite joint and the end
joint bave close, fine hairs.
S i X t h 1 i mb (fig. 7): — P r o t o p o d i t e: The first endite has two rather long and
powerful distal bristles, furnished with a few oblique wreaths of long, stiff secondary bristles,
and two to three short, plumous medial bristles. The second endite has two rather long and
powerful, subequal distal bristles, with a wreath of long, stiff secondary bristles at the middle and short
hairs distally; in addition it has three rather short, plumous medial bristles. The third endite
has four distal bristles, of which one of the dorsal ones is rather short and powerful, with a wreath
of long, stiff secondary bristles at the middle, and bare distally; the other three are rather long
and powerful, subequal, all of them sometimes of the sanie type as the distal bristles of the
second endite, sometimes two of them have short hairs; this joint has, in addition, one medial
bristle of about the same type and length as the distal bristles on the preceding endite. The
e p i p o d i a 1 appendage of the protopodite is represented by 5 rather short bristles,
either with short hairs or bare, fixed on a small, lobe-like process. E x o p o d i t e: The endite
of the first joint has from six to eight distal bristles, one of which is of about the same type
and size as the short distal bristle on the previous endite, a couple of ventral ones also rather
short, but weak with short hairs, the rest subequal, rather long and powerful, most of them
