FAM. AMPELISCIDA, G. O. Sars. 
AMPELISCA MACROCEPHALA. 
Ampelisca macrocephala, Lilljeborg. 
Coulman Island, 13 Jan., 1902, 100 fm. ; two males, length 18 mm. 
In these specimens the upper and lower antennz appear to be subequal, and reach 
to the urus. They (especially the upper) are therefore considerably longer than in the 
northern form as figured by G. O. Sars. The lower margin of the first joint of the fifth 
pair of perseopods is more truncate than in the female specimen in the ‘ Southern 
Cross ’ collection. 
FAM. STEGOCEPHALIDA, G. O. Sars. 
EUANDANIA GIGANTEA ? 
Euandania gigantea? Stebbing. 
W.Q., 20 Aug., 1903, Hole 12, D net; one specimen, length 9 mm. 
Probably a young specimen ; not dissected. 
FAM. LEUCOTHOIDA, G. O. Sars. 
LEUCOTHOE SPINICARPA. 
Leucothoé spinicarpa, Abildgaard. 
W.Q., 13 Sept., 1902, two; 5 Nov., 1902, one; 11 Nov., 1902, one; 28 Noyv., 
1902, one ; 8 Sept., 1903, two; 30 Sept., 1903, one. 
I am unable to see any difference between these specimens and the European and 
Ceylon forms. The largest measured 15 mm.

PROBOLOIDES ANTARCTICUS. (PI. 5, fig. 9.) 
Proboloides* antarcticus, A. O. Walker, Ann. and Mag. Nat. Hist. XVIII. (1906), p. 13. 
W.Q., from Feb. to Dec., 1902, sponges, Hut Point, ete. 
Female: Kpimeres of the third pleon segment with straight hind and lower 
margins, forming a rounded subrectangular posterior angle. Ocular lobe not very 
prominent, subrectangular. //ve round, colourless in spirit. 
* There can be little doubt that Dr. Della Valle is right in holding that Probolium polyprion, Costa, was a 
true Stenothoé. The very nearly allied Stenothoe gallensis, A. O. Walker, certainly is so, the mandibles having 
no palp and the lobes of the maxillipeds being separate. In Proboloides antarcticus the expansion inwards and 
distal prolongation of the joint which corresponds to the outer lobe of the maxilliped are sufficiently developed 
to form a rudimentary lobe. A similar form is shown by Stebbing in his figures of Metopa on Pls. XL. to XLVI, 
and as all these species have mandibular palps, and the inner or basal lobes of the maxillipeds distinct, they should 
now be included in Probolozdes, Della Valle, with the exception of M. ovata, which, from its two-jointed mandibular 
palp, might be referred to Proboliella but for the narrow first joints of the peropods.
