“ TERRA NOVA ’ EXPEDITION. 
Genus AUSTRORAPTUS, Hodgson. 
In addition to the genotype, A. polar is, 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 genus without much hesitation 
were it not for the character of the palps in a young specimen that I suppose to belong 
to A. polaris. If they have been correctly interpreted, the two new species retain 
respectively in the adult condition two different characters—the chelate chelophores 
and the eight-segmented palp—that are united in the larva of A. [whirls.
