tig. 27 of C. symmetrica). The exopodite is the same as in this figure. The protopodite
and the first exopodite joint are partly furnished with long hairs.
S i X t h 1 i m b: — This is about the same as in my tig. 29 of C. symmetrica, but, as is
the case in most of the other species of this genus, the ventral bristle on the end joint is furnished
with long secondary bristles.
The end joint of the s e v e n t h 1 i m b has spines.
Penis: — This is of about the same type as in my fig. 32 of C. symmetrica, only being
perhaps somewhat less elongated. At about the middle it is furnished with about six oblique
transverse muscles, distally of which there are no muscles. The copulatory appendage is rather
narrow, resembling in shape the type reproduced for C. Haddoni, but without serrulation.
F u r c a: —- Behind the claws there is an unpaired, moderately long, long-haired bristle,
of about the type shown in pl. XIX, fig. 14, C. CLAUS, 1891 a.
Rod-shaped organ: — The shaft reaches to about the proximal boundary of
the third joint of the first antenna or somewhat farther. The capitulum is of about the type
reproduced by 6. W. MÜLLER (see the accompanying fig. 3) and is not quite so long as the second
joint of the first antenna.
Upper 1 i p : — The part between the combs on the posterior ventral edge of this
lip is of about the type reproduced by me in my fig. 4 of C. Belgicae. The p a r a g n a t e s
are about the same as in C. symmetrica.
F e m a 1 e: —
Shell: — Length: According to G. W. Müller, 1,6—1,7 mm.; two females from
the Indian Ocean that were investigated by this writer measured only 1,4 mm.; cf. p. 682 above.
The lengths of the specimens investigated by me varied between 1,2 and 1,65 mm. Seen
from the side the shell is of about the type reproduced by C. Claus, 1891 a, pl. XIX,
fig. 2, consequently somewhat more elongated than in the male. Seen from b e 1 o w it
is of about the type reproduced in fig. 3 of the plate just mentioned, i. e. with its shoulder vault
less strongly developed. In other respects it is about the same as in the male.
First antenna: — This is of the type reproduced by C. CLAUS, 1891 a, pl. XIX,
fig. 6, but has a well developed dorsal bristle on the second joint; this bristle lias short hairs
and is almost as long as the second joint. The e-bristle, which is not widened and sword-shaped
distally, has on the anterior side of the proximal half a moderate number of rather short hairs.
The second joint is partly furnished with short hairs; the distal part of this limb is furnished
more or less abundantly with rather short hairs.
Second antenna: — The p r o topodite is somewhat weaker than in the
male. The proportions of the exopodite are about the same as in the male. E n d
o-p o d i t e: This has three joints; the third joint is, however, extremely small; cf. G. W . MÜLLER,
1906 a, p. 98. The bristles on the first joint are the same as the male. Second joint: Theg-bristle
is either of about the same type and relative length as in the male or else it is slightly shorter.
The f-bristle is about a quarter or a fifth shorter than the g-bristle and is also of the same type
as in the male. The c- and d-bristles are offen quite absent, sometimes une of tliem is developed;
see G. W. Müller, 1906 a, pi. XXI II, Hg. 33. Third joint: The h-, i- and j-1 »ristles are of somt -
