are no muscles. The point lias a complicated chitinous skeleton, but lias no copulatory appendage;
cf. the accompanying fig. 12.
Furca: — Bekind the claws there is an unpaired short-haired bristle of about the same
relative length as in fig. 33 of G. symmetrica.
Rod-s haped organ: — The shaft reaches to about the distal boundary of the
second joint of the first antenna or somewhat farther. The capitulum is somewhat longer than
the proximal height of the second joint of the first antenna and varies somewhat in type;
some-times it is of about the type shown in pi. I, fig. 15, V. Vävra, 1906, sometimes somewhat more
bent upward; cf. the accompanying figs. 6 and 7.
Upper lip: — The part between the combs on the posterior ventral edge of
the lip is of about the type reproduced in my fig. 37 of G. symmetrica or else the
median notch is somewhatdeeper. The paragnates are of about the same type
as in the species just mentioned.

Shell: — Length: According to G. O. SAKS, 1865, „circiter 2 mm.“; G. W. MÜLLER,
1901: 1,55—2 mm.; the saine writer, 1912: 1,55—1,8 mm.; V. YAyra, 1906; „durchweg 1,9 mm.“.
The specimens investigated by me measured 1,6—1,85 mm. Seen from the side (cf.
the accompanying fig. 2) it is of about the sanie type as the male shell, but the posterior part
of the shell is somewhat more developed. Seen from b e 1 o w, too, the shell agréés fairlv
well in both sexes; the same variation with regard to the side contours is to be noted; we must
note, however, that the posterior part of the shell in most cases dominâtes somewhat more over
the anterior part in the female than in the male. Seen from inside: The selvage has
a rather large spine-like process on the rostrum; see the accompanying fig. 4. In other respects
the shell resembles that of the male.
First antenna: (fig. 8) : — The dorsal bristle on the second joint is almost as long
as the distal sensorial filaments and has short, fine hairs. The e-bristle is about twice the length
of this antenna or somewhat longer and on the anterior side of its proximal quarter or third
has sparse moderately long hairs. This bristle is not widened and sword-shaped distally. There
are no pigment corpuscles in this limb. All the joints are bare.
Second antenna: — The protopodite is almost as well developed as in
the male. The proportion between the length of the protopodite and that of the exop odite
is also about the same as in the male. E n d o p o d i t e: This has two joints; I was unable
to discover any boundary between the original second and third joints. First joint: Both the
a- and b-bristles have short hairs. Second joint: The h-, i-and j-bristles are usually somewhat
shorter than the f-bristle. The g- and f-bristles have no shafts. In other respects these five
bristles are about the same as in the male. Between the h- and i-bristles there is an extremely
small process. Pilosity: The second endopodite joint is bare.
S i X t h limb: — The dorsal bristle on the end joint is in most cases about a third
shorter than the middle one, sometimes even somewhat shorter.
The rod-shaped organ is of about the type reproduced by Y. VAvra; cf. the
accompanying fig. 8.
