half as long as the posterior margin is broad; between these spines the margin is armed with 

 a dozen of movable spinules that measure one-third the length of the longer inner spines 

 near the postero-lateral angles and below these spines the long plumose setae are inserted. 

 Spines of the basal joint of swimmerets large, the outer somewhat longer than the inner. 



Second antennular article almost twice as long (0,56 mm.) as thick (0,32111111.) and 

 one-fifth longer only than the visible part (0,46111111.) of i st article; 3 1 '' 1 article a little shorter 

 than the visible part of the i st . Stylocerite terminating in a spine, that just reaches beyond 

 the i st article. 



Basicerite with a well-developed spine, long 0,2 mm. Carpocerite just as long as the 

 antennular peduncle, not longer, scaphocerite resembling that of A. Lanceloti and reaching a 

 little beyond the peduncles. Terminal joint of external maxillipeds almost 3-times as long as 

 broad at its base. 



Ischium of the small cheliped with two microscopical, movable spinules on the lower margin, 

 the anterior, 0,06 mm. long, 011e and a half as long as the posterior. Merus 3,5-times as long as 

 broad, upper margin unarmed; infero-internal margin armed with four movable spinules, 

 that progressively increase in length, the i st or proximal spinule being 0,07 mm. long, the 4 th 

 0,22 mm., and with a hardly visible, rudimentary tooth or spine at the far end. Carpus and 

 chela as in A. Lanceloti, chela somewhat more than 4-times as lone as hieh; fineers as lone 

 as the palm, the latter with a small obtuse tooth at the far end at the inner side, near the 

 articulation of the dactylus; lower half of the palm and immovable finger hairy. 



The very slender left leg of the second pair (the right is missing) is 2,2-times 

 as long as the carapace, rostrum included; the merus, 2,5 mm. long, is 1 4-times as long as 

 broad. Carpal segments 0,84 mm., 1,2111111., 0,62 mm., 0,76 mm. and 0,5 mm. long, the second 

 segment 8-times, the third 4-times as long as thick; chela 0,88 mm. (palm 0,38111111., fingers 

 0,5 mm.) long. The second segment of the slender carpus is almost one and a half as long 

 as the first and the fourth is not shorter, but one and a half as long as the fifth ; the fingers 

 which, according to Coutière's figure 39 c should be shorter than the palm in A. Lanceloti, 

 are in this new species distinctly longer than it, almost one and a half as long. 



Ischium of 3" 1 and 4* legs with a strong movable spine, long 0,32 mm. Merus of y d 

 legs f i v e t i m e s as long as broad in the m i d d 1 e , its posterior margin armed with 

 four movable spinules that increase in length; the very small first spinule is 0,07111111. 

 long, the second 0,1 mm., the third o, 13 mm., the fourth o, 15 mm., the length of the last 

 hardly more than one-third the width of the joint; the third is as far distant from the distal 

 extremity as the second from the proximal one. At the distal extremity this margin terminates 

 in a small, though q u i t e cl i s t i n c t , acute tooth, as in A. Mier si ; carpus slender, 

 unarmed, 4-times as long as thick distally, its anterior margin with some setae, one of which near 

 the far end is as long as the carpus itself. Propodus 6-times as long as broad, 1,25-times as 

 long as the carpus, its posterior margin with 6 pairs of spinules ; both margins are setose, two 

 or three setae near the anterior margin are plumose. Dactylus two-fifths of the propodus, 

 half as long as the carpus, sim pi e. Merus of 4 th legs also 5-times as long as broad, 

 resembling that of the 3 rd , but its posterior margin with three, instead of four, movable
