ANTARCTIO BENTHOS
141
As seems true for many other marine organisms, many more species
of marine algae occur on the Antarctic Peninsula and on the Antarctic
Islands of the Scotia Arc.
In all accounts of algae which follow, the nomenclature, whenever
necessary, has been altered to agree with that used by Papenfuss (1 964b).
Barton (1902) listed five species from Cape Adare. A. and E. S.
Gepp (1907) and Foslie (1907b) recorded ten algae from Victoria Land.
Lucas (1919) recorded 12 species from Commonwealth Bay. DBldpine
and Hureau (1963) reported on some algae from Adelie Land. I n all
these cases the material was collected while biologists were primarily
concerned with other work. The total flora from these localities is listed
below :

A. Algal ecology and zonation
Little of a comprehensive nature has as yet been published on the
general ecology and zonation of algae in the Antarctic. Most of what is
available is based upon studies of a relatively small area.
