setae like a mat, and has its edges serrulate : the fingers are not much more than 

 half the length of the palm. 



The 2nd and 3rd pair of legs closely resemble one another, both having 

 smooth compressed joints and ending in a long acute dactylus, which is at least 

 as long as the propodite and longer than the merus : the 2nd pair, which are 

 slightly the longer, are about as long as the body without the telson : both pairs, 

 when extended, reach beyond the 1st pair. 



The 4th pair of legs are as long as the carapace : their joints, though com- 

 pressed, are stout, and their dactylus is a short stout claw, which forms with the 

 produced angle of the setose propodite, a subchela. 



The 5th pair of legs are shorter than the carapace : they resemble the 4th 

 pair in having a setose propodite and a very short claw-like dactylus, which, 

 however, folds against the distal end of the propodite to form an imperfect 

 subchela. 



In the male the 2nd pair of abdominal appendages are two-thirds the length 

 of the carapace : they are strongly calcined, and their terminal joint is angularly 

 club-shaped. 



Colours in life : upper surface of carapace and legs orange, lower surface 

 white, eyes brown, eggs bright yellow. Spirit specimens are cream-colour with 

 some iridescence on the gastric region and on most of the abdominal terga. 



In a male the length of the carapace is 10 millim., of the abdomen 21 

 millim. An egg-laden female is a little larger. The eggs though large arc 

 fairly numerous. 



All the specimens known were found tightly impacted in sunken drift twigs 

 of bamboo and mangrove.

PABAPYLOCHELES, n. gen. 



Closely resembles Pylocheles and Mixtopagwnta. 



Differs from Pylocheles in the following characters only : 



A little rostrum projects between the bases of the eyestalks, and the lineas 

 anomuricae are distinct, though they do not reach the posterior border of the 

 carapace. 



Though the abdomen is faultlessly symmetrical, and though all the abdo- 

 minal terga are well denned and in close contact, yet there are no pleura, and on 

 the ventral surface of the abdomen (except for the presence of appendages) there 

 is no segmentation : moreover some of the terga are somewhat ill-calcified. The
