shorter than the second, which is four times as long as the third; 
flagellum of 30 joints in the male, 26 in the female, accessory of 
6 and 5 joints respectively. Second antenne with long peduncle, 
last joint a little longer than the penultimate, a little shorter 
than the 13-jointed flagellum. 
The mouth-organs and pereeopods do not seem to offer charac- 
ters of value specifically. The first gnathopods of the male are 
in near agreement with the figure and description given by 
Mr. A. O. Walkerin 1909. My figure was drawn before I had 
realized the necessity of comparing it with Mr. Walker’s. His 
description is, ‘hand three times as long as wrist, hind margin 
longer than palm, which is defined by a blunt, everted tooth, 
setose on the side; behind this is a large sinus followed by a 
prominent flat-topped tooth ; dactylus swollen near the middle.” 
In my specimen the front margin is rather longer than that in 
Mr. Walker’s drawing and the blunt tooth is not everted, but 
such differences may well be individual. In regard to the first 
gnathopods of the female, with their slightly excavated palm, 
Mr. Walker’s figure agrees fairly well with Dana’s and with mine, 
which also was drawn before comparison with Dana’s species had 
occurred to me as desirable. Mr. Walker speaks of the fourth 
and fifth pereeopods as having “the 2nd joints wider than in the 
‘Challenger’ specimen” (of LZ. kergueleni). That would not 
agree with the form here in question or with Dana’s figure. 
In the uropods Dana notices the long spines apical to the 
peduncles of the first and second pairs. In the first pair the 
rami differ slightly from Dana’s figure in being a little longer 
instead of a little shorter than the peduncle, but on Dana’s plate 
they are drawn in situ, which is unfavourable to minute accuracy 
of measurement. 
The telson is considerably longer than broad, a fact that 
would scarcely be suspected from a lateral view. Length of 
male in much curved position 7 mm., at full stretch probably 
10 mm. or more; female (with numerous eggs) nearly as long.
