“TERRA NOVA” EXPEDITION. 
Ammothea glacialis (Hodgson). 
Leionymphon glaciate, Hodgson, 1907, p. 50, PL vii, fig. 3. 
Ammotlica glacialis, Bouvier, 1913, p. 123. 
Occurrence .— Station 194, off Oates Land, 180-200 fathoms ; 1 young. Station 
220, oft' Cape Adare, 45-50 fathoms; 1 immature. Station 314, McMurdo Sound, 
222-241 fathoms; 5 immature. Station 318, McMurdo Sound, 130-180 metres; 1 
young. Station 322, McMurdo Sound, 20 metres; 1 ?. Station 338, Entrance to 
McMurdo Sound, 207 fathoms ; 2 $, 2 $ (ovig.), 3 immature. Station 340, off Granite 
Harbour, 160 fathoms; 2 $, 1 $ (ovig.), 2 immature, 1 young. Station 355, McMurdo 
Sound, 300 fathoms ; 1 $ (ovig.), 3 immature. Station 356, oft' Granite Harbour, 50 
fathoms ; 1 young. 
Remarks .—This species has hitherto been known only by the immature holotype 
obtained by the “Discovery” and an adult female recently recorded by Hodgson from 
the “ Gauss ” collection. It is the most abundant species of the genus in the collections 
of the “ Terra Nova.” 
Adult specimens are little larger than the holotype, with which they agree except 
as regards the chelophores and, in the males, the ovigers. The form of the proboscis is 
better indicated by Hodgson’s description than by his figure. The ovigers of the male 
have the distal segments modified as in other species of the genus; the terminal 
segment is little longer than the preceding.

Young Stages .—Four very young specimens included in the list given above 
(Stations 194, 318, 340 and 356) are only referred to this species with some doubt. 
Their most conspicuous character is the presence on the legs of coarse short spines set 
in longitudinal rows; in the smaller specimens each spine is elevated on a conical
