as the posterior margin is wide, the latter half as wiJe as the 

 width at base. 



Meropodite of right chelipede of the male 3 times as long as 

 the ischiopodite and 3 times as long as wide, presenting its 

 greatest width at -/^ of its length from the distal extremity ; 

 upper margin straight, lower S-like, the width at proximal extre- 

 mity being in proportion to the greatest width as 17 : 40. Chela 



1.4 times as long as the meropodite, reserabling the small chela 

 of A. djihoutensis (Coutière, Les Alpheidae, 1899, Fig. 209, the 

 left). Left chelipede unknown. Chelipedes of the female equal, 

 small, different from that of the male. Meropodite 3,5 times as 

 long as wide and 1,7 times as long as the carpus, which is 

 twice as long as thick distally; chela twice as long as the 

 ischiopodite and hardly longer thau the meropodite, length of 

 the chela in proportion to that of the fingers as 16: 7. 



Relative dimensions of 3rd pair: Meropodite 1,9 (cf), 1,82 (9); 

 carpus 1; propodite 1,92 (cf), 1,93 (9). Proportion between length 

 and width of meropodite, in the male, 4,42, in the female 5,2 ; 

 for the propodite these numbers are respectively 6,7 and 7,7. 

 Dactylus slender, '/g of the propodite, 5 times as long as wide, 

 with a small, ventral, accessory hook. 



Ova numerous, small, 0,42 — 0,45 mm. long. Length of male 



8.5 ram., of female 12 mm.
