WEBER-VAN BOSSE—MARINE ALG 281 
that the great depth at which it was gathered may in some measure account for 
this. It bears cystocarps, and these have a little funnel at the top, exactly as in 
G. compress«.

The specimens of the Seychelles are more branched than those of Mahé, Terné, 
still I believe that they belong to the same species; some branches recall those of 
C. minor.

Harvey described this alga under the name of Rhodymenia prolifera, but J. Agardh 
pointed out that the structure of the cystocarp was unlike that of Rhodymenia and 
similar to that of Calliblepharis. The alga differs, however, from the other species of 
this genus in bearing the cystocarps on the broad part of the thallus and not on special 
leaflets ; Agardh called it therefore Calliblepharis ? prolifera. As the specimens from 
Amirante were fertile, I studied the ripe cystocarps; they have the same structure as 
those of Calliblepharis, and I do not think that the absence of special leaflets should be 
a reason to maintain J. Agardh’s note of interrogation. 
It is remarkable to find Calliblepharis prolifera in Mr. Stanley Gardiner’s collection, 
since it had previously only been found in New Zealand.

As far as I could judge by the small fragment, the specimen belonged to H. divaricata, 
Grey. It differed from H. Valentig in the absence of small stellate spines.
