although containing developing ova (length six times the greatest width). Second tibia 

 the longest segment, half as long again as femur. Tarsus half as long as propodus, 

 ventral margin of each segment armed with numerous short spinose setae ; claw short, 

 auxiliaries relatively long (Fig. 35 c). Setae for the most part very minute.

Remarks. This species differs from all other Antarctic and sub-Antarctic species as 

 regards the chela, which recalls that of, e.g., A'^. grossipes (Fabr.) from the North Atlantic 

 (Hoek, 1881, p. 44, pi. iii, figs. 9-12, pi. iv, fig. i). The northern species, however, has 

 the tarsus elongated and longer than the propodus; there are also three or four very 

 long spines on the proximal ventral margin of the latter and the claw is much longer. 



The male is unknown, but the species probably belongs to group I. 



Distribution. One mile off the east coast of Bouvet Island.
