CKUSTACEA OF THE MEEGUI AECHIPELAGO. 271 



is continuous from the base to the tip, but the outer edge is 

 obliquely interrupted a little before the middle. The convex 

 inner surface of the smaller hand is covered with many hairs, 

 especially towards the fingers, which are very hairy on their 

 inner surfaces. 



The other legs closely resemble those of A. parvirostris. As 

 regards the structure of the carpopodites of the second legs, 

 this species resembles A. Edivardsii. The first joint is a little 

 more than twice as long as the second, and a little shorter 

 than the other four joints taken together; the third and fourth 

 joints are very short and equal, each being half as long as the 

 second joint ; the fifth joint is longer than the preceding, but still 

 a little shorter than the second joint ; in the largest specimen 

 these joints are respectively 3|-, 1^, f, |, and 1^ millim. long, in 

 the youngest example 2f, 1^, f, g, and f millim. In the largest 

 specimen the hand is a little shorter than the last three joints 

 of the wrist taken together, in younger specimens it is slightly 

 longer ; the fingers are constantly a little longer than the palm, 

 whereas in A. Edwardsii they are as long as, or even slightly 

 shorter than, the palm. 



The form of the legs of the third and fourth pair is very charac- 

 teristic of this species, and resembles that of A. j^arvirostris ; they 

 are, indeed, less slender than those of A. lEdivardsii, and the mero- 

 podites are armed at the distal ends of their inferior margins 

 with an acute spine which is not found in Audouin's species. 

 These legs are a little hairy and the propodites are armed along 

 their inferior margins with two or three rows of small spines. 

 The legs o£ the fifth pair are also a little less slender than those 

 of ^. JEdwardsii, which they otherwise resemble. The uropoda 

 are almost exactly similar to those of Audouin's species, being 

 armed at the base with two acute spines, and the outer rami 

 present two or three spines at the external angle of their pos- 

 terior margins. The largest specimen is 28 millim. long from 

 the tip of the rostrum to the end of the terminal postabdominal 

 segment. In the second specimen, likewise a male, the larger 

 hand is 13|^ millim. long, and 6 millim. broad ; whereas in a speci- 

 men of A. Edwardsii the larger hand, presenting a similar breadth 

 of 6 millim., is 15| millim. long, appearing therefore comparatively 

 more slender than that of A. Hippothoe.
