. Fig. 21. Lateral view of head of A, Trematomus pennellii; B, T. centronotus. x \. Hab. Mac-Robertson Land; Queen Mary Land; Adelie Land; South Victoria Land. The types of this species, 2 specimens 175 and 210 mm. in total length, are from McMurdo Sound, 187 to 375 metres. It is very like T. pennellii, and, apart from the stiff and pungent dorsal spines, it scarcely differs from that species except in the larger eye. T. centronotus appears to be found in rather deeper water than T. pennellii. Trematomus scotti (Boulenger). Notothenia scotti, Boulenger, 1907, Nat. Antarct. Exped. Nat. Hist., 1
