Port Phillip Heads near Melbourne, Australia, and. was distributed 

 under the name of Scinaia furcellata. 



Pseudoscinaia australis differs from Pseudoscinaia Snyderae in 

 being less robust, in having slightly smaller cystocarps and having the 

 utricles ordinarily less elongated. The cystocarp is very distinctly like 

 that of Galaxaura, but lacks paraphyses. 



It may be that this plant is the same as the Scinaia furcellata var. 

 australis J. Ag. (1876, p. 512), but it has not been compared with 

 authentic material. Consequently it is necessary to consider it foi* 

 the present as distinct. It is known, at present, only from the type 

 locality. It is probably the plant referred to by J. Bracebridge 

 Wilson in his "Catalogue of Algae collected at or near Port Phillip 

 Heads and Western Port" (1892, p. 173 as above) under Scijiaia 

 furcellata and may also be included under Harvey's reference to 

 Scinaia furcellata in the "Synoptic Catalogue of Australian and Tas- 

 manian Algae" in the fifth volume of the "Phycologia Australica" 

 (1863, p. xxxviii). A specimen collected by Harvey at Western Point 

 and referred to Sciiiaia furcellata is, however, the type of Gloiophloea 

 Scinaioides J. Ag.
