THE TYSON COLLECTION OF MARINE ALGAE 
Pseudocodium de Vriesii, Web. von Bosse. 
Cape Morgan, Kei. 
(Isipingo. Barton (2).) 
Note. This genus is not mentioned in Engler and Prantl, but as both 
West (ii) and OltmannsC) recognize the genus it is added at the 
end of the Codiaceae, together with the next genus, Codiophyllum, 
which Engler and Prantl (5) place at the end of the family as 
being of doubtful systematic position. 
Codiophyllum natalense, Gray. 
Kowie. 
24. Valoniaceae. 
3. Apjohnia rugulosa , Murray. 
Cape Morgan, Kowie, Kei mouth. 
(Algoa Bay, Cape, Natal. Barton (l).) 
5. Chamaedoris annulata, Mont. 
Durban. 
(Table Bay. Barton(i).) 
11. Anadyomeme stellata, Ag. 
Durban. 
PHAEOPHYCEAE. 
1. Ectocarpaceae. 
Note. In all the collections made between S. James’ and Glencairn 
during October and November of this year we have found a brown 
filamentous alga which we have placed provisionally in the genus 
Pylaiella. 
2. Ectocarpus, sp. 
Cape Morgan. 
Note. Miss Barton (l) records the following species: E. parvulus, Klitz., 
Cape Agulhas; E. confervoides , Le Job. Kalk Bay; E. simplicius - 
cuius, Ag., Kalk Bay; E. siliculosus, Lyngb., Cape, South Africa; 
E. granulosus, Ag., Cape. 
We have found several species of Ectocarpus between Kalk Bay 
and S. James’ during October and November. Certain of the 
smaller species may have been overlooked earlier in the year, but 
we suspect that their development may be seasonal. The only 
species that we have named with certainty is E. siliculosus, Lyngb. 
The other species we have named provisionally: E. confervoides, 
Le Job (this is an extremely large species reaching as much as 
three feet in length in the small bathing pool at Kalk Bay); 
E. simpliciusculus, Ag. (epiphytic on various other Algae), and 
E. Hincksiae, Harv. (represented by one small specimen only). 
Note. Miss Barton (2) records another genus of the Ectocarpaceae, viz. 
Streblonema Codii, n. sp. from Knysna.
