VOL. IV,] Some New and Some Old AlgiT. 361 



plant is at times beset with very small radiating articulated 

 threads (parasites ?). Color reddish brown. A small alga ^-i 

 inch high, forming in patches on rocks and sides of cliffs at high 

 water mark. 



It is with reluctance that I add another name to the long list 

 of Callithamnions, now already numbering more than two hundred. 

 But this little plant, so small, so abundant, is not like any in my 

 herbarium; and finding no description of it, I venture to enlist it 

 as new, having but little doubt. 



It grows abundantly about Monterey Bay, and I have 

 received a specimen from Mrs. Bingham, of Santa Barbara. It 

 may readily be distinguished by the following characters: The 

 tetraspores and ramuli emerge near the middle of the articulation; 

 its small size; its perennial growth; its reddish brown color; 

 and growing on rocks and sides of cliffs at high-water mark. 



BONNEMAISONIA HAMIFERA, Hariot. 



[Class, Rhodophyce^; Order, Laurenciace^.) 

 This unique and very pretty alga has but recently been 

 described by Mons. Hariot coming from Japan. Professor 

 Farlow of Harvard, has had specimens from Santa Barbara but 

 for a time considered them the same as B. asparagoides, Woodw. , 

 of the Irish Coasts. 



In 1892 Mrs. Winston, Bradley M. Davis, M. A. Howe, and 

 others collected specimens near Pacific Grove. Plants having 

 been sent to Professor Farlow he has kindly determined them. 



In the March number oi Erythea for 1893, Mr. Howe pub- 

 lishes this alga in a list of his collections on Monterey Bay. As 

 he truly says, "it is beautiful and noteworthy." One of its 

 striking features is remarkably well-formed imitations oi fish- 

 hooks at and near the tips of the branchlets, much like those of 

 Hypnea miisciformis but more graceful. 



Dasya coccinea, Huds. 



{Class, RhodophycE^; Order, Rhodomelace^.) 



This beautiful alga has been collected in Monterey and Car- 

 mel Bays for some years; but until the summer of 1892 was not 

 recognized as the old world Dasya, first described by Hudson in
