AbstractDuring the austral summer seasons of 1963-1964 and 1964-1965, and during the austral winter season of 1967 Prof. Dr. J.S. Zaneveld made collection expeditions to the western Ross Sea. In 1965 collections were also made from the U.S.C.G. icebreaker ‘Glacier’, around the western Ross Sea and around the Balleny Islands. During the same cruise Macquarie Island was visited. Most collecting was carried out by means of scuba-diving. Prof. Zaneveld was accompanied on these expeditions by W.I. Simmonds (1963-1964), J.M. Curtis (1964-1965), J.K. Fletcher (1964- 1965), D.M. Bresnahan (1967), and L.L. Nero (1967), during these periods students at Old Dominion University, Norfolk, Virginia, U.S.A.
In the harsh Antarctic environment the algae discussed in the present paper occur in aquatic habitats (freshwater, brackish water, and saline water) be it covered with ice or not, in melted snow and on icebergs.
Identification and synonymy of the eleven taxa reported is based mainly on the Antarctic and sub-Antarctic literature. One of the algal taxa mentioned belongs to the Xanthophyceae and ten to the Chlorophyceae. Several of these taxa are newly recorded for the area or part of it under discussion.
Some critical notes are made concerning the Antarctic Ulotrichales, as well as a short discussion on the correct name of the type species of the genus Klebsormidium. A new species of this genus is described.
The species collected ar Heterococcus moniliformis Vischer, 1937; Chlamydomonas aft. ballenyana Kol in Kol & Flint, 1968, Stichococcus nivalis Chodat, 1917; Klebsormidium drouetii Wagner & Zaneveld, nov. spec.; Ulothrix implexa (Kützing) Kützing, 1849; Ulothrix australis Gain, 1911; Urospora penicilliformis (Roth) Areschoug, 1874; Monostroma hariotii Gain, 1911; Prasiola crispa (Lightfoot) Meneghini, 1837 var. antarctica (Küitzing) Knebel, 1935 forma antarctica (Kützing) Knebel, 1935; Chaetomorpha mawsonii Lucas, 1919; and Lola-irregularis Zaneveld, 1966.
The remarkable vertical distribution of the chlorophyte Monostroma hariotii in the Ross Sea, Antarctica, i.e. from the lower eulittoral down to 348 meters indicates again that the factor ‘light’ is only one of the many features influencing the vertical distribution of marine algae.
