spines are 14 to 18, 3 or -1 behind the orbit, ventral spines -1 to 6, ter- 

 minal third of rostrum unarmed. The maxillipeds reach nearly to the 

 end of the antenniilar peduncle; the first pair of feet not quite to the 

 end of antennal peduncle; the carpus is about one and a half times as 

 long- as wide, longer than the palm of the hand; the fingers longer than 

 the palm. The second pair of feet reach to the end of the antennal 

 peduncle; carpus and propodus subequal in length, palm enlarged dis- 

 tally, shorter than the fingers. The propodus of the fifth pair of feet 

 is three times as long as the dact^^lus. 



A female with ova measures 22.8 mm. long; the eggs are 0.9 mm. 

 long. 



Kurume, Japan; Jordan and Snyder, July 23; 1 female with ova. 

 Near Fusan, Korea, in fresh-water streams; P. L. Jouy; many 

 specimens. 



This species is very close to, perhaps identical with, C. pareparensis 

 de Man,« from Celebes, which has a shorter rostrum, with only 2 

 inferior teeth.

Kurume, July 23; about 25 specimens. 



In most of the specimens the rostrum is broken ofi' near its base; in 

 none is the tip perfect. 



Dorsal spines 17 to 23 (2 on carapace); ventral spines 11 in the only 

 specimen where complete (Stimpson says 10). Anterior third or 

 fourth unarmed above, except near the tip, where there is at least one 

 spine. Antennal spine high, quite above the antenna. The color and 

 white spots described by Stimpson are not visible in the preserved 

 specimens.
