IV. FISHES. 



By G. A. BOULENGEK, F.R.S. 

 (Two Plates.) 



THE collection is a very small one, consisting of representatives of ten species only, 

 from within the Antarctic Circle, but of these four are here described as new. In 

 addition to these species an example of a very large Nototkenia, apparently closely 

 related to N. colbecki, Blgr., was obtained, harpooned, with a seal, from a hole at the 

 Winter Quarters. It was in a damaged condition, the head gone, and the caudal fin 

 partly torn away. All I have seen of the fish is a photograph and the bones of the 

 body. Dorsal with viii, 27 rays, anal with 26 ; scales, in a longitudinal series, 125. 

 Total length, 3 ft. 10 ins. ; weight, 39 Ibs. (without the head).
