Austropallene brachyura (Bouvier). 
Pseudopallene brachyura, Bouvier, 1911, p. 1138 ; id., 1913, p. 98, figs. 51—54. 
Austropallene spicata, Hodgson, 1914-15, p. 144. 
Occurrence .—Station 314, McMurdo Sound, 222-241 fathoms; I Station 338, 
Entrance to McMurdo Sound, 207 fathoms; 1 $. Station 340, off Granite Harbour, 
1G0 fathoms; 1 7, 1 immature. 
Remarks — The specimens differ from Bouvier’s account of this species in the 
following points: The spurs on the lateral processes and first coxse are distinctly 
longer ; on each lateral process, in addition to the spurs, there is a small tubercle about 
the middle of the distal edge; and the second coxse have, on the dorsal surface, two 
rows of tubercles, much more prominent than in Bouvier’s figure, and some of them 
almost spiniform. Like the holotype, all our specimens are females, and although 
somewhat larger, their measurements show a close agreement in proportions. There 
can, I think, be little doubt that Hodgson’s Austropallene spicata has been founded on 
the male sex of the same species. The two syntypes that 1 have examined are both 
males, and they agree very closely with the “ Terra Nova ” specimens except for a 
slightly greater slenderness of body and a marked increase in the relative length of the 
second coxse. 
Austropallene tibicina, sp. n. (Text-figs. 7 and 8). 
Occurrence. —Station 220, off Cape Adare, 45-50 fathoms ; 3 ?, 2 $ (inch Holotype). 
Description .—-Resembling A. hrachyura in general form, but more slender and 
with the spurs of the body and legs much larger. 
Cephalic segment nearly half the total length of the trunk, anterior dilatation 
about two and a half times the diameter of the neck. Ocular tubercle low, obtuse, 
much smaller in diameter than the neck, eyes well-separated, reddish. 
Lateral processes separated by intervals of at least their own diameter, the first 
with one, the others with a pair of large distal spurs, and each also with a small 
conical tubercle in the middle of the distal margin. The lateral processes and their 
spurs are more elongated in the male than in the female. 
Proboscis contracted, about the middle of its length, to a slender, downwardly- 
curved tube, with a conspicuous brush of setae on the three terminal lips. 
Abdomen relatively a little larger than in A. brachyura, directed obliquely 
upwards. 
Chelophores slender, the scape more (l) or less (7) than four times as long as 
thick, shorter than the proboscis. Chelae not more than two-thirds the length of the 
scape, movable finger strongly arched, toothless, shorter than the palm, immovable 
finger extending far beyond it, curved only at the tip, with two blunt tubercles between 
which the tip of the immovable finger fits; both fingers sharply pointed. 
Oviger of male with fifth segment twice as long as fourth, bearing a short lateral 
process at its distal end.
