E. INTERMEDIUM Cleve, forma scRoBICULATA, n. f. (Text-fig. 1, G.) 
Canala; in ditch. 1359. The alga was not common. In form it is very near 
Eu. intermedium, differing chiefly in its scrobiculate cell-wall and larger 
lateral lobes. It is very similar also to Eu. orientale W. B. Turn. (Freshw. 
Alg. E. India, p. 79, t. 10, £. 34, t. 11, f. 26), but differs in the polar lobe, 
which in Turner’s species, as in Ku. insigne, is 4-lobed, whilst in Eu. inter- 
medium it 1s 2-lobed. 
MICRASTERIAS DECEMDENTATA Niig., forme. Canala; in ditch, 1359. 
The specimens were numerous and very variable, all intermediate stages 
between two extreme forms being present. One of these forms was identical 
with that figured by Schmidle (Süsswasseralgen aus Australien, 1896, p. 410, 
t. 9, f£. 18), and also by Playfair as M. truncata (Corda) Bréb., var. decem- 
dentata Playfair (Some Sydney Desmids, 1908, p. 608). The other form was 
also figured by Playfair (ibid. t. 9, fF. 8-9) as M. truncata var. laticipiformis 
Playfair. The dimensions of the specimens from Cinala were: long. 88- 
110 a; lat. 108-116 a.

The cells were small and very depressed, being slightly broader than long.
