and reproduced by G. W. MÜLLER, 1901; un both tbe right and left antennae there are
cross-ridges distally; the right elasping organ may or may not have a few small chitinous verrucae
on its proximal shank. The h-, i- and j-bristles are subecpial and in most cases soniewhat,
though only slightly, shorter than the f-bristle; they are of about the same width as the f-and
g-bristles distally of their shafts and are bare; none of them has any traces of a shaft.
Mandible: — Protopodite: Coxale : The toothed edge on the pars incisiva
has from about nine to eleven teeth, of which the posterior ones are in a number of cases somewhat
more developed than in my fig. 16 of C. symmetrica. The distal tooth-list is of about the same
relative size and type as has been described for C. oblonga above. The proximal tooth-list is
of about the same relative
size and type as is described
below for C. spinirostris, but
the teeth seem to be on an
average somewhat, though
only rather slightly, fewer.
The part situated proximally
of this tooth-list is also of
about the same type as in
the last-mentioned species.
Basale : The six teeth on the
distal edge of the endite are
furnished with rather fine
serrate teeth. The single
tooth on the outside of this
endite is of about the same
type and size as in my fig. 19
of C. symmetrica; in most
cases it is finely serrulated
a long the greater of both the
posterior and the anterior edge; its point seems, however, to be smooth in most cases. The
disto-medial bristle of this joint is in most cases somewhat longer than in most species of this genus.
There is no epipodial appendage. E n d o p o d i t e: The first joint has only two
posterior bristles, which have about the same position and relative length as in C. spinirostris.
Maxilla: — This is of the sanie type as is described below for C. spinirostris.
Fifth limb: — This is of about the type described on p. 630 above for C. elegans,
but in the specimens investigated by me there was never more than one tube-bristle dorsally
of the short dorsal claw on the endopodite; in addition the shorter bristles in the ventero-distal
group on the first exopodite joint were usually somewhat longer relatively than in the species
just mentioned.
Penis (see fig. 11): — This is very powerful, relatively high and distally rounded. It
has from about eight to thirteen transverse muscles in the distal half; distally of these there
