Coccomyxa dispar SCHMTDLE var. antarctica var. n. (Figs. 22-23) Proximum adest ad Coccomyxa dispar Schmidle sed differt ab ea : 1. forma et 2. dimensione cellular urn (3-4 /

tiX7-9 p). Habit in nive viridis Insula Haswel, Antarctica. Cells elliptical or cylindrical, occasionally slightly arcuate (Fig. 22), 11-4 u wide and 7-9 u long, with a very thick, colourless mucous envelope. It stands near SCHMIDLE'S Coccomyxa dispar, differing by 1. its size (smaller), 2. and ID some extent in its shape.
