Here, with much of the external aspect of a Sporochnus, we 

 have a perfectly new and distinct genus, more nearly related to 

 Bellotia (to be figured in our next number) than to any other ; 

 but so different from that in habit, that its claim to separation 

 will be readily admitted. From SporocJmus it differs in the 

 position and structure of the receptacle ; from Bellotia in the 

 evolution of the branches, and the possession of lateral, brush- 

 like ramelli. It establishes therefore a generic type almost ex- 

 actly intermediate between Sporochnus and Bellotia, but far 

 from uniting these genera, it rather strengthens the characters 

 on which they have been respectively established. 



This is one of the many discoveries we owe to Mr, Clifton, of 

 Western Australia, who is indefatigable in investigating the algo- 

 logical treasures of that colony, and from whom, while this sheet 

 is passing through the press, I have received an additional hatch 

 of interesting Algse, among which is another new genus, which 

 I purpose hereafter to figure under the name Cliftonia. Mean- 

 time the present species is gratefully and deservedly dedicated 

 to its discoverer.
