Map 4 issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.71]. Chart showing the geographical distribution (white circle) in the seas surrounding the Antarctic continent. Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).
Antarct. (Peninsula, Weddell Sea, SE Atlant., Indian, SW & SE Pacif., Ross Sea), ? South Georgia, sub-Antarct. (SE Pacif.), Sargasso Sea (in Deevey & Brooks, 1977, p.264, Station "S" : 32°10'N, 64°30'W), ? off S Iceland, SW Indian (in Grice & Hulsemann, 1967, p.16), Japan (off Sanriku), SE Hokkaido, Station Knot, Bering Sea, S Aleutian Basin, S Aleutian Is., Alaska Peninsula, off British Columbia (rare), off Is. Juan Fernandez, Chile
Bathypelagic. Sampling depth (Antarct., sub-Antarct.) : 0-2000 m. Sargasso Sea: 1500-2000 m (Deevey & Brooks, 1977, station "S"); According to Brodsky (1950, p.234) the form, described by Esterly (1906 a) as Xanthocalanus similis is a juvenile of O. magnus, but this is neither followed by Vervoort (1950 a), nor Park (1983 a, p.335, 339) and Bradford et al., 1983 (p. 61, 66).
