number of fine, rather flexible, long, sparse hairs; no. 7 is of about the same type as no. 1, but
somewhat stronger. Of the live inner bristles of the second endite (fig. 13) the two anterior
ones are rather strong subequal, moderately long and both of the same type; they are rather
strongly pectinated distally and may or may not have a wreath of rather long, stiff secondary
bristles proximally of the middle. The posterior bristle is of the same type as the former ones
but is considerably more powerful. Of the two middle bristles, both somewhat shorter than the
former ones, the anterior is finely serrate distally and has no long secondary bristles; the posterior
one, which is the shortest, lias in the middle a wreath of long secondary bristles, distally it is
smooth or perhaps with a fewr exceedingly weak secondary teeth. The remaining bristle on
this endite, situated on the anterior side of the process, a short distance from the five former
ones, is very short and bare. Of the seven bristles of the third endite (fig. 14) the two anterior
ones and the posterior one have the sanie type and about the same size as the corresponding
bristles on the second endite, nos. 3 and 4, counting from the anterior side of the limb, agréé
with no. 3 on the process mentioned, no. 5 is quite short and bare or has a few long and
rather soft hairs, no. 6 is moderately long and strong and has short, fine hairs. The distal
spine of the protopodite is unusually long and powerful. The epipodite has from 55
to 60 bristles, all furnished with long hairs right to the point. The exopodite has four
joints: First joint: The main tooth (fig. 15) has seven constituent teeth all well defined proximally;
the secondary teeth on the latter of about the sanie type as is shown in the adjoining figure,
but vary, however, to some extent. The bristle close to the main tooth on the posterior side
of the joint resembles in type and size the posterior bristle on the third endite. On the anterior
side of this joint there are four bristles, three of which are situated close together in a row near
the main tooth, the other one a short distance from these, farther out on the joint; two of the
three former ones are subequal and rather long and strong (about the same as is shown in the
figure 22 of C. (Vargula) norvegica), the third is somewhat shorter; one of the two long ones is
rather strongly pectinated distally, the other has exceedingly fine, short hairs distally, both
have stiff. long hairs in the middle; the short one has long, stiff hairs in the middle, short hairs
distally, almost bare. The ou ter one of this joint’s bristles is somewhat shorter than the two
longer of the former bristles and has long, soft hairs along the greater part of its length, short,
fine ones distally. Second exopodite joint: This has four powerful a-bristles with numerous
moderately powerful secondary teeth continuing almost to the points of the bristles; in addition
this joint has eight b-bristles, one c- and one d-bristle; the two latter are somewhat shorter
than the longest b-bristles and have rather close, long, soft hairs at the middle and short hairs distally.
The outer and inner lobes of the third exopodite joint are well developed (fig. 16); the outer one
somewhat larger than the inner one. Each of these lobes has two subequal bristles of moderate
length, with long, fine hairs at the middle and short, fine hairs distally. The end joint (fig. 16)
is about the same size as the outer lobe of the preceding joint and is furnished with two
bristles of the same type and size as the bristles on this joint, Pilosity: The outer lobe of the
third exopodite joint and the end joint are partly provided with close, soft, fine, long hairs.
Sixth limb (fig. 17): - Protopodite: The first endite has two or three
rather long and strong distal bristles, two of which usually have a few oblique wreaths of long,
