“TERRA NOVA ” EXPEDITION. 
Genus AUSTROPALLENE, Hodgson. 
Hodgson (1915, p. 144) lias recently proposed this genus for the reception of 
those Antarctic species hitherto referred to Pseudopallene or to Cordylvchele, which 
have a pair of spurs on the cephalon over the bases of the chelophores, and no terminal 
claw on the ovigers. Neither character is quite satisfactory, for the northern species 
of Pho.richilus (— Pseud opallene) have a group of conical tubercles in place of the 
cephalic spurs, and one of these tubercles may be larger than the others ; while in 
Austropallene there is usually, perhaps always, a minute terminal spine, if not a “ claw," 
on the oviger. 
Austropallene cornigera (Mobius). 
Pseudopallene cornigera, Mobius, 1902, p. 186, PI. xxvii, figs. 14-20; Hodgson, 1907, p. 7,

Re marks .—Differences of some importance exist between the specimens recorded 
under this name, without, however, affording ground for the recognition of more than 
one species. The relative length of the legs varies considerably, in some cases equalling 
that of the “ Valdivia ” specimens, and in others not exceeding the proportions recorded 
by Hodgson and by Bouvier. The following measurements (in mm.) are taken from 
specimens chosen as having nearly the same body-length :—

Variations in the outline of the proboscis, the direction and length of the cephalic 
spurs, and the development of spurs on the lateral processes, all tend to confirm the 
synonymy given above, which combines the suggestions of Hodgson and of Bouvier. 
In all cases, however, the terminal lips of the proboscis are setose, not merely 
tubereulated as Bouvier found them.
