vot. Iv.| Some New and Some Old Alge. 361 
plant is at times beset with very small radiating articulated 
threads (parasites ?). Color reddish brown. A small alga ¥/-1 
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, RHODOPHYCEA; 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 BZ. asparagotdes, 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 of Frythea 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 of /is/- 
hooks at and near the tips of the branchlets, much like those of 
Hypnea musciformis but more graceful. 
DasyaA coccinea, Huds. 
(Class, RHODOPHYCE; Order, RHODOMELACE4}. ) 
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
