Copepoda Arctic West Greenland (Jespersen, 1934), 500-1,500 m; and the Norwegian Sea (Ostvedt, 1955), 600-2,000 m, could be either or both species. The investigation of 5. magnus in the Antarctic has likewise been hampered by the co-occurrence of the two closely related species. The material of Hardy and Gunther (1935) and Vervoort (1951, 1957, 1965) should be reexamined. Wilson (1942) combined S. magnus from two samples (sample 41, Table

Wilson (1942) combined S. magnus from two samples (sample 41, Table 3); the composite did con- tain S. magnus and both stations are considered valid records. The other three samples reported by Wilson to contain S. magnus were not located but were collected at intermediate positions. Wilson (1950) reported 5. magnus from the China Sea, but the sam- ple so labeled did not contain any Spinocalanidae and the record is considered invalid. Some of Farran's specimens of S. magnus are in the collection of the National Museum of Ireland, Dublin (O'Riordan, 1969). The holotype of S. latifrons Sars is on slides F5041-F5043, OSLO. 5.
