M a n d i b 1 e : — This linib agrees almost completely with the one described above
for C. symmetrica, but all the four bristles on the posterior side of the first endopodite joint
have short hairs.
Maxilla: — Most of the bristles on the endites of both the procoxale and the coxale
are verv powerfully armed. Endite on the procoxale: The three antero-inner bristles are furnished
with long secondary bristles and all the postero-outer tube-bristles have rather long spines.
( )n the maxilla of one side there were four postero-outer tube-bristles in the specimen
investi-gated by me; the accessory (abnormal?) bristle was of about the same length as the three others

but considerably weaker than these. The spines situated distally-medially on the first
endopodite joint are relatively large and powerful. The end joint is about the same as in
O. borealis.
F i f t h 1 i m b: — This is about the same as in C. symmetrica. The two shorter of
the three antero-ventral bristles on the endopodite have short hairs.
Seventh limb: — The end joint has spines.
The furca, u p p e r 1 i p and paragnates are similar to those of C. symmetrica.
Rod-shaped organ: — The shaft extends somewhat distally of the point of the
first antenna; see the appended fig. 3. The capitulum is of about the type described and
repro-dueed by G. W. MÜLLER.
Habitat: — Antarctic Ocean:
