FAM. AMPELISCID^, G. 0. 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 antennae 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. 0. Sars. The lower margin of the first joint of the fifth 

 pair of pergeopods is more truncate than in the female specimen in the ' Southern 

 Cross ' collection. 



FAM. STEGOCEPHALIDiE, G. 0. Sars. 



Etjandania 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. LEUCOTHOID^, G. 0. Sars. 



Leucothoe spinicarpa. 

 Leucothoe spinicarpa, Abildgaard. 



W.Q., 13 Sept., 1902, two; 5 Nov., 1902, one; 11 Nov., 1902, one; 28 Nov., 

 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. 



FAM. STENOTHOIDiE., G. 0. Sars. 



PrOBOLOIDES AlfTARCTICUS. (PL 5, fig. 9.) 

 ProMoides* antarcticus, A. 0. Walker, Ann. and Mag. Nat. Hist. XVIII. (1906), p. 13. 



W.Q., from Feb. to Dec, 1902, sponges. Hut Point, etc. 



Female : Epimeres of the third pleon segment with straight hind and lower 

 margins, forming a rounded subrectangular posterior angle. Ocular lobe not very 

 prominent, subrectangular. E^/e round, colourless in spirit. 



* There can be little doubt that Dr. Delia Valle is right in holding that Probolium polyprion, Costa, was a 

 true Stenothoe. The very nearly allied Stenothoe gallensis, A. 0. 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 Pis. XL. to XL VI., 

 and as all these species have mandibular palps, and the inner or basal lobes of the maxillipeds distinct, they should 

 now be included in Proboloides, DeUa 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 perseopods.
