THE TYSON COLLECTION OF MARINE ALGAE 
(Olifants River to Algoa Bay, Robben Island, Kalk Bay, Cape 
Point, Knysna. Barton (l).) 
C. nuda, Kiitz. 
Green Point. 
(Cape Agulhas. Barton(i).) 
C. sp. 
Cape Morgan. 
Note. Miss Barton (l) records the following additional species: C. medi- 
terranean Ktitz., Cape Agulhas; C. spinulosa, Kiitz., Cape Agulhas; 
C. glomerata, Kiitz., Port Natal; C. afra, Kiitz., Knysna; C. rupes- 
tris, Kiitz., Cape; C. trichotomy, Kiitz. (doubtful record), between 
Omsamcolo and Omcomas; C. virgata, Kiitz., Table Bay. She 
also records the following doubtful species: C. capensis, Ag., Cape; 
C. aculeata, S., Algoa Bay; C. radiosa, S., Algoa Bay, mouth of the 
Zwadtkap. 
All the species represented in Tyson’s collection are large and 
it is quite evident that several of the smaller species of Clado- 
phora will have to be added to the collection. We have found at 
least two of these smaller species, one of which we have identified 
as C. rupestris, Kiitz. 
Near the train terminus at Sea Point we found abundant 
material of C. Eckloni and C. flagelliformis and noted the fol- 
lowing points. The latter is by far the coarser of the two and is 
blue green in colour while the former is a bright green. C. Eckloni 
is found in shallow pools, further from the shore than C. flagelli- 
formis which usually frequents somewhat deeper pools.
