" TERRA NOVA " EXPEDITION. 



Genus AUSTRORAPTUS, Hodgson. 



lu additiou to the genotype, A. polaris, I have provisionally included in this 

 genus two species, apparently new, which differ from it in characters that might justify 

 generic separation. One species, however, is represented by a solitary specimen, and 

 it is not quite certain, though it is probable, that it has assumed adult characters. 

 The other species might have been removed from the geuus without much hesitation 

 were it not for the character of the palps in a young specimen that I suppose to belong 

 to A. j)olaris. If they have been correctly interpreted, the two new species retain 

 respectively in the adult condition two ditferent characters — the chelate ehelophores 

 and the eight-segmented palp — that are united in the larva of A. polaris.
