MAEINE ALG.^ OF THE ' SEALAEK ' EXPEDITION. 117 



tliat the great depth at which it was gathered may in some measure account for 

 this. It hears cystocarps, and these have a little funnel at the top, exactly as in 

 Cr. compressa.

Terne Mahe ; dry specimens. 



Seychelles, Long Island ; dry specimens. 



Distribution. Ked Sea. 



The specimens of the Seychelles are more branched than those of Tcrn^ Mahe, 

 still I believe that they belong to the same species; some branches recall those of 

 C. minor.

Amirante, 25 fms. ; dry specimens. 



Distribution. New Zealand. 



Harvey described this alga under the name of Bhodymenia pi'olifera, but J. Agardh 

 pointed out that the structure of the cystocarp was unlike that of BJwdymenia and 

 similar to that of Callihlepharis, 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. Asardh's note of

It is remarkable to find Calliblepharis proUfera in Mr. Stanley Gardiner's collection 

 ice it had previously only been found in New Zealand.

Aldabra, fragment only, lagoon ; dry specimen. 

 Distribution. Gulf of Mexico ; Mascarenes (?) ; Tongatabu. 



As far as I could judge by the small fragment, the specimen belonged to JI. dimricata 

 Grev. It differed from H. Valentice in the absence of small stellate spines.
