c^ Carpocerite not longer than antennular peduncle. Proportion 

 between length and height of the large chela in the female 

 less than 2, the palm being just as long as high. Upper and 

 lower margin of the palm very rugose. Second legs as in 



Aut. Evermanni rugosa Cout. 



(H. COUTI^RE, in: Bull. Mus. Paris, 1902, p. 341). 



A, Rostrum distinct, though small and rounded. Carpocerite hardly 

 longer than the antennular peduncle. Scaphocerite just reaching 

 beyond the middle of second antennular article. Visible part 

 of basal article much shorter than the eye-peduncles. Second 

 antennular article much longer than the visible part of the first. 



Second legs as in Atit. dolichos:natIia Gardineri Cout. 



(H. COUTIERE, Alpheidae Maid, and Laccad. Archip. 1905, p. S54, Fig. 127, 128). 



(^3 Rostrum triangular, the obtuse tip reaching almost as far forward 

 as the anterior margin of the carapace. Eye-peduncles therefore 

 much shorter than the visible part of basal antennular article. 

 Scaphocerite not reaching to the middle of second antennular 

 article. Second carpal segment of second legs only one-third 



longer than the first . Talis)uani Cout.

a„ Rostrum triangular, acute, reaching, beyond the frontal margin, to 

 the distal third part of the eye-peduncles. Scaphocerite extending 

 to the apex of second antennular article Saloinoni Co'ut.

It remained uncertain to which species these specimens belong, because all have lost 

 their legs of the first pair, but they probably belong either to Aiit. Gardineri Cout., a species 

 observed in the Maldive Archipelago and at Kingsmill Island, or to Aut. doIicJiognatJia de Man 

 from the Java Sea. 



The largest specimen is a female from Stat. 19, long 15,5 mm. The median frontal 

 process is triangular, obtuse and resembles that of Aut. Gardineri (H. Coutiere, Alpheidae 

 Maid, and Laccad. Archip. 1905, Fig. 127c?). Eye-peduncles also as in this species. The visible 

 part of the basal antennular article measures two-thirds the length of the eye-peduncles and 

 appears just half as long as the median article, when the latter is measured along its inner 

 margin ; the median article which is 3-times as long as thick, appears 3-times as long as the 

 third article. The eye-peduncles measure but a little more than one-fourth the length of the
