distally; the tongue of the distal bell is also rather sharply cut off distally (about the same type
as is shown in fig. 25 of C. (Vargula) norvegica); proximally of the bells these bristles are smooth.
The end eomb consists of five narrow, bare, rather weak teeth, one central tooth and two teeth
placed symmetrically on each side of this. The central tooth is long, not quite so long as the
height of the limb, and is rather pointed distally. The two proximal teeth are considerably
shorter; the one situated most proximally is the shortest, being only about a quarter or a fifth
of the length of the central tooth; distally they are somewhat rounded. The concavity dorsally
near the end comb has on its dorsal edge a reduced verruciform process.
Penis (fig. 14) : — This is of the type that is characteristic of the sub-family. See the
accompanying figure for details. A very large gland situated ventrally in the penis has its exit
on the ventral process 0f the pincers.
Furca: — This is of the same type as in the type species. It differs in the two following
characters from this as it is represented by G. W. MÜLLER, 1906 b, pl. III. fig. 5: all the claws
are furnished with teeth; the second to the fifth teeth on claws nos. 4 to 8 are considerably
coarser than the distal ones.
The u p p e r 1 i p agrees with that of the type species.
The rod-shaped o r g a n (fig. 5) of moderate length, rather thick, slightly pointed
distally.
The latéral ey es are, as in the case of the type species, situated somewhat above
the middle of the shell.
Female: —
Shell:—Length: 1,6—1,7 mm. Lenght : height, about 1,75: 1. Seen from the side
(fig. 2) it shows fairly close agreement with the shape of the shell in the type species, the
principal differences being that the ventral corner of the rostrum is somewhat more pointed and that
the posterior beak-shaped process is developed rather more powerfully; this process is only
slightly smaller than that of the male and has about the same shape. The surface of the
shell is similar to that of the male. Seen from inside (fig. 3): Medial bristles: These
seem to be somewhat fewer than in the type species; their nurnber seems, however, to vary rather
considerably. From 14 to 26 were observed on the rostrum (the maximum nurnber is shown
in the accompanying figure); these were arranged in two almost parallel rows, the posterior
of which, situated along the posterior edge of the rostrum, is very sparse dorsally,
some-times represented at this part by only a few solitary bristles. The bristles on the list behind
the rostral incisur are considerably more sparse than is shown in the figure of the type species.
On the right valve from 12 to 14 spines of the same type as in the male were observed posteriorly
on the list; of these from none to three of the ventral ones were very small. On the left valve
the spines may apparently be quite absent. The bristles on the part of the list that has spines
seem to be somewhat fewer than in the male.
First antenna: — This, like that of the male, has seven joints; at least in some
cases, however, the fifth and sixth joints seem to be less closely united than in the other sex.
The joints have about the same relative proportions as in the male and the bristles on the third,
i’ourth and sixth joints and the a-bristle on the seventh joint also show a rather close agreement
