Carte de distribution de Euchirella latirostris par zones géographiques
Espèce Euchirella latirostris - Carte de distribution 3issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.41]
Chart showing the geographical distribution (white triangle) 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).
Espèce Euchirella latirostris - Carte de distribution 4issued from : J.C. von Vaupel Klein in Zool. Verh. Leiden, 1998, 323. [p.392, Fig.5].
Map showing the distributional areas of E. rostrata (Claus, 1866), E. rostromagna Wolfenden, 1911, and E. latirostris Farran, 1929 , respectively; note the considerable overlap in range of E. rostrata and the other two species which, in their turn, are virtually coinciding in a strictly geographic sense. Antarctic convergence i(AC).
