MONOGllAPll or THE AMiMUNOMAOEA. ^10 



I'eet promiueut. Setse of the upper or dorsal tuft (fig. 2 a) finely 

 capillary, terminating in an acute long point. They are nearly 

 quite simple, are indistinctly covered with minute prickles for a 

 short distance below the apex, but have no serrations or teeth on 

 their edge, and are five or six times longer than those of the lower 

 or ventral tuft (fig. 2 5), which are short, stout, curved at tlie apex, 

 which is rather blunt, but quite simple or free from serrations. 

 In the shape of the caruncle and in the bristles of the lower 

 or ventral tuft of the feet this species approaches near to A. 

 rostrata, but it differs in the structure of the bristles of the upper 

 or dorsal tuft. In this species they are capillary, finely acumi- 

 nated, and nearly quite simple, whilst in rostrata they are stouter, 

 and finely but distinctly serrated on both margins. The bristles 

 of the lower or ventral tuft, again, in jukesi, are shorter, more 

 curved, and not quite so horny in appearance as in rostrata. 

 This species, too, is much smaller than rostrata, and of even a 

 more quadrate or square shape.
