and about as wide as the f-bristle proximally, bare or with extremely short and fine hairs. The
h-bristle has a spinous shaft, the f-, g-, i- and j-bristles have no shafts.
Mandible: — Protopodite: Coxale: The toothed edge of the pars incisiva
has about ten teeth. The distal tooth-list is of about the sanie relative size and type as has
been previously described for C. oblonga, but the nurnber of teeth is on the average somewhat
fewer. The proximal tooth-list also varies within about the same limits as the eorresponding
part in the species just mentioned, but here, too, the number of teeth is on the average somewhat
less. The masticatory pad is very powerfully developed; it is divided into from four to six more
or less distinct transverse ridges; the distal one of these is about as wide as the two
tooth-lists, the next distal one is about half as wide, the others decrease somewhat in width the more
proximally they are situated. The whole masticatory pad is armed with rather small papillae,
placed close together. The part of the pars incisiva that is surrounded by the lancet bristles
and hairs is rather powerful and is armed with papillae similar to those on the masticatory
pad; this part is also armed with a couple of low and powerful teeth. Basale: The six teeth on
the distal edge of the endite are furnished with moderatelv fine serrulation. The single tooth
on the outside of this endite is more powerful than in my fig. 19 of C. symmetrica and is of the
same type as has been described for C. elegans. The epipodial verruca is very small
and has a very short bristle. The exopodite verruca is very weakly developed.
Endopodite: The first joint has only two posterior bristles, botli with short hairs; these
have about the same position and relative length as the two eorresponding bristles in C.
rotundata. Pilosity: The second endopodite joint has hairs.
Maxilla: — Protopodite: Endite on the procoxale: Besides the anterior
inner tube-bristle the two bristles nearest to this are also provided in most cases with long
secondary bristles. The basale has no bristle. Endopodite: First joint: The six bristles
on the anterior side of this joint are somewhat relatively shorter than in most other species of
this genus. The end joint is of about the same type as in C. rotundata.
Fifth li mb: — Pr o topo di te: The longer of the two tube-bristles on the
second endite has short hairs. Endopodite: This is similar to that of C. oblonga.
Exopodite: The first joint is similar to that of the above-mentioned species, but all the
ventral bristles usually have short hairs. The ventral end claw varies in length; sometimes
it is only a quarter or a sixth of the length of the middle claw.
Sixtli li mb: — Exopodite: The ventral bristles on the first joint are
sometimes somewhat relatively shorter than in my fig. 29 of C. symmetrica; the dorso-lateral and
dorso-distal bristles sometimes seem to be quite absent.
Penis: — This is of the type reproduced by G. \Y. MÜLLER, 1906 a, pl. XXX, fig. 9;
it has a rather narrow copulatory appendage; cf. the accompanying fig. 5.
Eur ca: — There is no unpaired bristle behind the claws.
Rod-shaped organ: — The shaft reaches to about the distal boundary of
the second joint of the first antenna or somewhat farther. The capitulum is of about the type
described and reproduced by G. W. Müller or else it is somewhat more curved in anteriorlv;
cf. the accompanying fig. 6; it is sometimes somewhat more pointed distally than in
