than the first, the third a little shorter than the second, 
the whole peduncle does not reach to the distal end of 
the scales of the lower antennae and the spinule at the 
extremity of the first joint is short, measuring a third of 
the second joint. The outer foot-jaws do not reach to the 
extremity of the scales, but project almost with their whole 
terminal joint beyond the peduncle of the lower antennae. 
The legs of the first pair reach to the extremity of the 
peduncle of the inferior antennae and are similar to those 
of Car. pareparensis. The rather deeply excavated carpopo- 
dite is short and only once and a half as long as broad 
and the fingers have the same length as the palm. The 
slightly longer legs of the second pair almost extend to 
the extremity of the scales and also agree with those of 
Car. pareparensis, as the wrist is a little longer than the 
chela, of which the fingers are scarcely longer than the 
palm. The legs of the third pair project a little beyond 
the scales, those of the fourth extend a little less fore- 
ward than the second pair and about as far as the legs 
of the last pair. The dactylopodites of the last pair, that 
are a little less slender than those of Car. pareparensis, 
being not yet five times as long as broad, are armed at 
their inner margin with nearly 45 spinules and measure 
about a third or nearly a third of the length of the 
propodites.

A single adult, ova-bearing female was collected to- 
gether with the preceding species, in the freshwater lake 
of Nefko, Timor. 
The rostrum of this specimen, that is 28 millim. long, 
is lanceolate, slightly directed downwards, reaches only 
to the middle of the third joint of the anten- 
nal peduncle and shows 31 teeth on the upper margin,
