Chinstrap penguin at McMurdo Sound
riot suitable for both Stylatractus universus and seudoemi1iania lacunosa. Although the cause of the extinction levels may be in doubt, the extinction clatums are nonetheless strati graphically important and useful.

A single chinstrap penguin (Pygoscelis antarctica) was observed on 26 January 1974 at the edge of the September/October 1975

ice channel leading to McMurdo Station. The penguin was seen approximately 3 kilometers north of McMurdo Station from aboard USCGC Staten Island. George A. Llano, Office of Polar Programs, National Science Foundation, and George M. Jonkel, Office of Migratory Bird Movement, U.S. Fish and Wildlife Service, confirmed the sighting. The only other documented sighting of a chinstrap in the McMurdo Sound area was at Cape Royds in 1908 (Murray, 1909). Other chinstraps in the Ross Sea have been observed at Cape Crozier (Sladen et al., 1968) and at Cape Hallett (Crawford, 1974). The chinstrap penguin is found primarily in East Antarctica, but over the last 20 years evidence has accumulated that it is in progress of considerably extending its range (Conroy, 1975).
