The last pera^opods liave a large forward projection of the 

 basal joint edged with fifteen long plumose set«, while the 



Harpinia lafipes. Last perseopod, 



posterior lobe is largely di^veloped, reaching downward to 

 the extremity of the meros ; the margin cut into nine serra- 

 tions, five of which are very large, the uppermost of all 

 considerably smaller, and the three lowest smaller still ; a 

 small seta is situated at the base of each serration ; the 

 ischium has eight setse on the anterior margins, the central of 

 which are long and plumose ; the isciiium, meros, and carpus 

 are subequal in length; the hand slightly longer and the nail 

 longer than the hand. 



The above description is taken from separated mounted 

 limbs ; the specimen itself 1 cannot at the present time find, 

 so am unable to give further particulars, but the last perseopod 

 at once distinguishes it from all described species, and in the 

 anterior lobe of the basal joint finds its counterpart only in 

 Harpinia abyssi, G. O. Sars, from which the deeply cut 

 posterior lobe at once distinguishes it, 



Hab. A single female specimen taken by the ' Porcupine,'
