Description. — Body clumsy. Carapace large, covering the trunk excepting the 

 posterior dorsal half of the last segment; its posterior margin feebly emarginate. Frontal plate 

 in the female (PI. VII, hg. 3^) large and anteriorly produced into a considerable, triangular, 

 acuminated rostral part; the plate in the male (fig. 3a) is proportionately smaller, but the 

 produced rostral part is more acuminated with the lateral margins more concave, forming a 

 narrow process bent much downwards. Eyes conspicuously larger than in A. typica and slightly 

 broader than the end of the stalk, brown or dark-brown ; eye-stalks increasing in breadth towards 

 the eye. Antennular peduncles longer and very much thicker in the male (fig. 3a) than in the 

 female (fig. 3^). Antennal squama small in both sexes, about two and a half times as long as 

 broad; second (apparently first) joint of the endopod in the female (fig. 3 c/) shorter than the 

 breadth of the squama, in the male (fig. 3 f) extremely large, thick and only a little shorter 

 than the length of the squama. 



Gnathopods in the female (figs. 3// and 3 i) simple; in the male very different (figs. 3^ 

 and 2>f) '■ second joint proportionately much larger, fifth joint considerably widened and besides 

 on the inner side with a very large, oblong-triangular, distally blunt, lamellar process directed 

 inwards and much forwards; sixth joint broad. First pair of thoracic legs (fig. 3^) similar in both 

 sexes and shaped nearly as the following pairs, with sixth joint divided by three articulations. 



Lateral wings of the first abdominal segment in the female (fig. 3/-) much larger than 

 in A. typica, increasing in breadth from the front end and posteriorly produced in a somewhat
