A male from the hill-streamlets of the island of Great- 
Bastaard, near the north-eastern coast of Flores. 
Two ova-bearing females from Maumeri, Hast-Flores. 
The male is 90 millim. long. The rostrum extends as 
far foreward as the antennal peduncle, the upper margin 
is somewhat convex and slightly directed downwards at 
the extremity. The upper margin is armed with ten teeth, 
of which the first is a little more distant from the second 
than the following, of which the third is placed justly 
above the anterior margin of the cephalothorax, whereas 
the foremost tooth, that stands near the apex, is nearly 
twice as far distant from the ninth, as the ninth from 
the eighth. The inferior margin is armed with three teeth. 
The rostrum therefore shows a great resemblance with 
that of a male specimen from Timor, that has been for- 
merly figured by me (I. c. fig. 346). 
The right leg of the second pair is only present, of 
which the meropodite measures 11 millim., the carpopo- 
dite 17 millim., the palm 15 millim. and the fingers 
8'/, millim. The fingers are armed with some small teeth 
along the proximal half of their inner edges. 
The two females are respectively 75 millim. and 65 
millim. long. 
The formulae of the teeth of their rostra are 1+ and 
14; in the former specimen the third tooth stands above 
the anterior margin of the cephalothorax, in the other 
immediately behind it and in both specimens the teeth 
extend along the whole length of the upper margin un- 
til near the apex. In each specimen one of the legs of 
the second pair is deficient; in both, however, the two 
fingers of the remained leg show several small teeth along 
their inner edges. :
