For Vervoort (1963 b, p.123) the records specimens of Davis (1949, p.25) from off Cape Flattery (eastern Pacific) differ in minor particulars from those recorded from Atlantic localities, and considers these Davis' records with some reserve. The specimens recorded by A. Scott (1909, p.40) as A. rostrata, generally identified with A. multiserrata, also differ from Atlantic specimens in certain details. Amongst A. Scott's specimens of A. rostrata from Siboga collection Vervoort found a single immature female of A. trichecus (see in Vervoort, 1949, p.9). He points out that he does not consider A. trichecus to be identical with A. rostrata as described by A. Scott (1909, p.40), this in contradiction to Tanaka's statement (1957, p.40); Vervoort considers A. trichecus to be more closely allied (if not identical with) A. divaricata Esterly (1911, p.316) than either A. multiserrata or A. rostrata.
After Markhaseva (1996, p.37) A. multiserrata was recorded in the Arctic Ocean (Brodsky, 1950; Minoda, 1967; Vidal, 1971; Markhaseva, 1984), but according to the figures (Brodsky, 1950; Vidal, 1971) and the examined original material from the Arctic Ocean, it is A. minor and not A. multiserrata; thus the previous recordings of A. multiserrata in the Arctic Ocean are doubtful. | | | Last update : 25/10/2022 | |
