its distal breadth, in an adult female 85 times. The fingers are 

 longer than the palm and are unarmed. 



The second peraeopods bear a conspicuous subterminal spine 

 on the lower side of the merus. In large males they m^y be as 

 much as 6 time? the length of the carapace, extending beyond the 

 scale by more than the length of the carpus and chela. The legs 

 of a pair are equal or subequal and similar in structure. As in P. 

 a gag the second legs of males are closely covered with minute as- 

 perities only visible under a microscope. 



In large males (text-fig. 53ft) there is a conspicuous tubercle

at the distal end of the lower border of the ischium. The merus 

 is from 70 to 80 times as long as broad. The carpus is from I'o 

 to 1 '2 times as long as the merus and from yo to 80 times as long 

 as its distal breadth. The distal end of the carpus is similar in 

 structure to that of P. agag and does not bear a conspicuous spine 

 on the inner side (text-figs. 53c, d). The chela is from 14 to 17 

 times the length of the carpus ; the palm is about 5 times as long 

 as wide and from 195 to 22 times the length of the fingers. In 

 all the males examined, the fingers meet throughout their length 

 when the claw is closed. 1 Each is armed in the proximal half 



1 The number of large specimens in the collection is small ; it is very prob- 

 able that more highly developed males with gaping fingers remain to be dis- 

 covered.
