species, but the tail is truncate and not rounded, the principal outer rays being as 

 long as the inner ones. The pores on the upper surface of the head are, on the 

 whole, as illustrated, but the median pore is placed more forward than shown, so that 

 the five interorbital pores form a cross, the median pore being nearly in the axis. 



Young examples have much the appearance of Notothenia hodysoni, Boul.,* 

 and were so tentatively named by Mr. Murray. I have, however, examined the 

 scapular arch, and find them to possess the distinguishing character of Trematomus ; 

 moreover, the vertebrae number fifty-four, which is the number given by Boulenger 

 for T. newnesi. 



The localities of the eleven specimens submitted are as follows : 



Nos. 1-6. Backdoor Bay (Priestley), 5-10 fathoms, February 6, 1909. 

 No. 7. The Bay, Cape Royds, 5-10 fathoms, May 8, 1908. 



No. 8. " In mouth of Big-head," taken in fish-trap, Cape Royds, 25 fathoms, 

 September 1908. 



Nos. 9-11. The Sound, Cape Royds, 10-25 fathoms, July 1908.

The larger of the two specimens preserved was contained in a bottle with 

 examples of Trematomus newnesi, labelled " Backdoor Bay, Priestley, five to ten 

 fathoms, February 6, 1909"; the smaller [one was with specimens of T. hansoni, 

 August 25, 1908. 



The appearance of the fishes suggests that they were taken from the stomachs of 

 a larger fish, or of a seal, all the fins having been more or less digested away. 



The type specimens were also in poor condition, but were sufficiently complete to 

 enable an accurate description and figure to be made, as confirmed by Vaillant,t 

 who had two excellent examples from the " Francaise " Expedition. He was enabled 

 to give a greater range in the number of fin rays, and shows that a rudimentary 

 lateral line exists on the hinder part of the body, whereas Boulenger did not find 

 trace of such. Vaillant gives detailed descriptions and figures of the scales. The 

 scales, though thin, are very adherent, and many of them still remain on our fishes, 

 though, as above stated, the digestive process has proceeded to a considerable extent, 

 and in the case of the larger example has removed the whole of the hinder part of 

 the body. 



One of our fishes appears to have been larger than any previously obtained, 

 though its length, except by analogy, cannot be measured ; in its mutilated state it 

 measures ] 78 mm. The head, exclusive of the projecting lower jaw, is 55 mm. in length,
