on the e-bristle. None of these three bristles is widened distally or has a pad-like appendage.
All the joints are quite bare.

Second antenna: — Protopodite: Length 0,3—0,4 mm. Exopodite:
The proportion between the length of this branch and that of the protopodite is about 10:13.
The proportion between the length of the first joint and the total length of the eight
following joints is about 10 : 4. The proportion between the length of the longest
nata-tory bristles and that of this branch is about 14 : 10. As far as I could observe the
first joint is quite bare. En dopo dite: This is of about the type described and repro-

duced by G. W. MÜLLER; the length of the f- and g-bristles bears a proportion of about
2 : 3 to the length of the protopodite. The a- and b-bristles have short hairs, the other
bristles are bare.

M a n d i b 1 e: — Protopodite: Coxale: The toothed edge of the pars incisiva
is of about the sanie type as in C. rotundata, but its teeth, apart from the large anterior one,
are somewhat smaller relatively; this part may be described as evenly and finely serrulated;
the number of the teeth is somewhat larger than in the species mentioned, about 14—18 were
observed. The distal tooth-list is of about the sanie type as in C. rotundata. The proximal
tooth-list is also of about the same type as in this species, but the number of its teeth seems
