number of long stiff secondary bristles at the middle. Pilosity: The outer lobe of the tliird
exopodite joint and the end joint have at parts soft hairs.
S i X t h 1 i m b (fig. 20) : — Protopodite: The first endite has one rather long
and powerful distal bristle, furnished with some wreaths of long, stiff secondary bristles and,
in addition, with two short, plumous medial bristles. The second endite has three distal bristles;
two of these are rather long and powerful and furnished at the middle with long, stiff
secondary bristles, the dorsal one with short hairs distally, the ventral one rather strongly
pectinated distally; the third is very short and bare or almost so. This endite has, in addition,
two moderately long, plumous, medial bristles. The third endite has three distal bristles, two of
which are rather long and powerful, with long, stiff secondary bristles at the middle and short
hairs distally, the third is rather short and has short hairs; in addition this endite has a moderately
long medial bristle, which is plumous at the middle. The e p i p o d i a 1 ap pendage of
the protopodite is represented by five rather short bristles, which are bare or almost bare.
Exopodite: The endite of the first joint has the same equipment of bristles as the preceding
endite; the ventral distal bristle, is, however, somewhat longer. The second exopodite joint
has 32 bristles ventrally (the same number on both the right and the left limbs of the only
specimen that was investigated) ; a number of these bristles are displaced rather far from the
ventral edge up on the inside of the joint; there is no proncunced gap between the posterior
bristles and the others. The two posterior bristles, as is pointed out in the diagnosis of the
subgenus, are very large, directed backwards and furnished with long, soft hairs situated close
together along their whole length. The other bristles are of different lengths, some rather long,
some short, and of different types, some with long, stiff secondary bristles at the middle and short
hairs distally, some with only short hairs; the long secondary bristles are only weakly arranged
in wreaths; the short-haired bristles are usually the shortest. Pilosity: On the inside the limb
has close, short, fine hairs; the second exopodite joint has latero-ventrally only groups of
extre-mely short and fine hairs, but distally these hairs become somewhat longer.
Sevent h limb (figs. 21 and 22): — This is very long, being almost as long as the
sheik Cleaning bristles: Concentrated ventero-distally there are from 17 to 20 bristles varying
somewhat in length; a few of the distal ones are moderately long or rather short; then there are
a few rather long ones; the rest are moderately long or short; these bristles are furnished with
from one to seven bells. On one side of the limb, proximally of and near the end comb, there
are two moderately long bristles situated close to each other and furnished with five or six bells.
In addition there are 15—19 ventral and thirty dorsal bristles scattered irregularly; these vary
somewhat in length; some are rather short, usually furnished with three (in exceptional cases
with only one or two) bells, some rather longer, usually with five (in exceptional cases four)
bells. The bells are cut off transversally distally; the tongue of the distal bell is cut off very
obliquely (of about the same type as that shown in figs. 27 and 28 of C. (Macrocypridina) castanea).
Proximally of the bells the cleaning bristles are smooth. The end comb consists of eleven or
twelve distal teeth and on each side of these eight proximal teeth. Round the distal half of the
„lower jaw“ at about equal distances from each other there are twelve simple, conical, pointed,
bare and rather long and strong teeth.
