First antenna, basal joint stout with a few small serrations on 

 inner margin, 2nd joint one-third length of 1st, 3rd joint shorter than 

 2nd, only 4 joints of the flagellum remaining, accessory flagellum 

 2 -join ted. 



Second antenna, 1st joint broad, 2nd narrower but equal in length 

 to 1st, 3rd joint shortest, 4th and 5th successively longer, flagellum 

 3-jointed, 2nd joint longest, 3rd very small, scale on 2nd peduncular 

 joint as long as 3rd joint, with 2 apical setae. 



Upper lip with distal margin evenly rounded, epistome with a 

 tubercle in centre. 



Lower lip, basal portion broad, the lobe on the exterior distal angle 

 ovate, margins minutely setulose, apex acute. 



Mandibles similar to those figured by G. 0. Sars for A. spinosus, 

 M. Sars, cutting-edge on left mandible quadridentate, on right 

 tridentate, secondary cutting-edge on left tridentate, 1st joint of 

 palp short, 2nd and 3rd subequal, twice as long as 1st. 



First maxilla, outer lobe with 6 spines in pairs, the backwardly 

 directed palp with 2 long and 1 short setae (inner lobe lost in 

 dissection). 



Second maxilla, all three lobes equal in width. 



Maxillipeds, 2nd joint largest, inner plate distally truncate and 

 slightly emarginate, 5th and 6th joints nearly as broad as long, their 

 apices broader than their bases, inner margins of inner plate, 4th and 

 5th joints, and apex of 6th setose. 



First peraeopod (gnathopod), 2nd joint largest, ovate, (3rd absent) 

 4th and 5th slender, oblong, 5th longer than 4th, 6th and 7th 

 together nearly equal to the 2nd joint, thumb of 6th joint with a 

 square projection just before the apex on inner margin, a few setae 

 on outer and inner margins, 7th joint evenly curved with a low 

 rounded process just before the unguis. 



Second peraeopod, 4th joint with one spine on both outer and 

 inner apices, 5th joint with one spine on outer apex and 2 spines on 

 inner margin, 6th joint not expanded, with 2 spines on outer apex 

 and 4 on inner margin, 7th joint nearly as long as 6th, slightly 

 curved. No epipods were observed either on the 1st or 2nd 

 peraeopods. 



Eemaining peraeopods not very slender, 5th and 6th joints with 

 2 small spines on inner margin, 7th joint with a tubercle on inner 

 margin before the unguis. 



The number and structure of the pleopods could not be determined 

 as they appear to be completely absent, owing probably to an injury 

 either before or after capture.
