edge. Dorso-distally on the coxale there is a rather large lamelliform epipodial
appen-d a g e. The exopodite is comparatively well developed, with close, fine, long hairs;
it is not displaced distally. The endopodite is broad and moderately long.
Sixth limb: — The second exopodite joint is rather short and somewhat
rounded with numerous bristles; its posterior-distal bristles are not strikingly large in comparison
with the other bristles.
S e v e n t h 1 i m b : — This has rather numerous cleaning bristles, of which a rather
large number are situated very close to each other distally, the rest scattered irregularly along
the distal part of the limb. With regard to the position of these latter bristles it is to be noted
that on the same side of the same joint there is only extremely seldom more than one bristle.
The end comb consists of a moderate number of rather powerful teeth, some rather long, distally
rounded distal teeth, smooth except that at the middle they have a small secondary spine on
each side, and decreasing somewhat in length the more proximally they are situated, some
rather shorter and broader, quite bare proximal teeth rather sharply cut off distallv. Dorsally
close to the end comb the wall of the limb is rather strongly thickened and also rather deeply
concave. The ventral part of the wall in this notch is continued proximally as a peg of
ehitin with which the chitinous part that forms the dorsal wall of the notch is moveably joined;
this latter chitinous part ends dorsally in a freely projecting, rather powerful little verruca.
The ventral and the dorsal walls of this notch mav be pressed together somewhat like a jaw,
when the distal teeth of the end comb are also pressed in towards the dorsal edge of the notch;
this compression is carried out by a short, powerful, paired muscle, issuing somewhat
proximo-dorsally of the point of the limb and fixed to the bottom of the notch, both to the ventral
and the dorsal chitinous hinge. This muscle seems to be a specialized part of the anterior
longitudinal muscle of the limb.
Furca: — The lamellae are moderately elongated; the number of claws is about
eleven; there is no clear division into main claws and secondary claws.
Upper lip: — This has no large processes and is onlv slightly divided into fields;
one can distinguish one anterior upper unpaired field of glands, the openings of which are directed
a nteriorly-ven trally and two posterior-ventral fields with the openings of the glands directed
ventrally; these glandular fields are divided from each other only by shallow grooves. There
is an unpaired protubérance on the front between the upper lip and the rod-shaped organ.
The median eye is well developed and is of ordinary size and type. The
rod-shaped organ is fairly well developed and rather short and thick.
The lateral eyes are well developed.
Xumher nj sprrirs Remarks: — As far as I know this sub-genus comprises only the two species described
below. Possibly one or more additional representatives of it may be found arnong the rather
numerous species of this sub-family that have been dealt with in the literature; on account of
the incompleteness of the descriptions nothing can, however, be stated with certainty about this.
neiatinn hetwcen ihr With regard to the relation between the two species I will only point out here that the
spmes. form C. (D.) levis found at South Georgi a is certainly to be regarded as more divergent
