Penis: — This is of the fundamental type for this sub-family. For details see the
accompanying figure 20. There seem to be no glands on the ventral lobe.
Furca: — Very like that of the female; the two or three distal claws are, however,
somewhat more curved.
The rod-shaped organ and the u p p e r 1 i p agréé vvith these organs in the
females.
The latéral eyes are slightly larger than those of the females.
The dorsal side of the back of the body has rather strong transverse
folds or ridges.
Habitat: — South Georgia:

Type specimen, on slides, R. M. S.
C. (Doloria) pectinata n. sp.
Description: — Female: -
Shell: — Length, 2,45—2,8 mm. It agrees completely with the shell of C. (D.)
levis. The peculiar formations (pores?) of the list inside the posterior border of the
shell are, on the average, somewhat more numerous?
First antenna: — This agrees verv closely with that of the preceding species;
a slight, but apparently constant, difference is, however, to be noted with regard to the sensory
bristle of the fifth joint. Of the ten long proximal sensory filaments that distinguish this bristle
of the preceding species, the distal one is in this species displaced rather much distally and is,
in addition, somewdiat shortened and narrowed; it thus constitutes a sort of transitional form to
the more distallv situated filaments, the sharp division into long, somewhat thicker proximal sensory
filaments and short, narrow, distal ones being thus less marked in this species. On one specimen
two (normally only one) subequal anterior distal bristles were observed on the fourth joint on
the antenna of one side.
Second antenna: — Pro topodite: The medial-distal bristle is rather long,
about twice as long as the three shorter of the four proximal bristles of the first endopodite
