Discovery reports (1940) Discovery reports discoveryreports18inst Year: 1940 NOTOTHENIIDAE 33 Island, at a depth of i metre, identified by Roule, Angel and Despax as A. nicolai, is 135 mm. in total length, and is in very poor condition. Scales are apparently present on the occiput, but not on the interorbital region, and I have little doubt that the specimen should be referred to this species. The British Graham Land Expedition obtained 9 specimens (133 to 230 mm.) from fish traps at approximately 65° S, 65° W, and one specimen (95 mm.) thrown ashore at Barry Island (68° S, 67° W). Fig. 1

Very similar to the preceding species, but length of head 3 J to 3 in that of fish (without caudal); diameter of eye (3I young) 4! to 4! in length of head; interorbital width about 5 (6 in young); interorbital region naked in young, but with 2 or 3 series of scales in the middle in adult and half-grown specimens. 55 to 59 scales in a longi- tudinal series, (30) 34 to 37 in upper lateral line. Dorsal V, 33-38. Anal 31-32. Pectoral I to I length of head, about as long as pelvics, which just reach the anal. Hab. South Georgia. The type of T. vicarius, 240 mm. in length without the caudal fin, was taken outside Boiler Harbour, Cumberland Bay, South Georgia, at a depth of 30 metres. This species is very close to T. bernacchii, and may eventually prove to be no more than a local race. Notothenia dubia was based upon 3 spe
