the most grateful reward of my labours ; and now that he is removed, my interest in 
the work has sensibly flagged, and I am not sorry that it is brought to a conclusion. 
Since the previous part was issued, two other of my correspondents have been 
numbered with the dead — Professor Tuomey of Alabama, and Dr. Blodgett of Key West, 
to both of whom I was indebted for very valuable contributions of specimens. Many 
of these have been noticed in the two former parts, and several more will be found 
described in the present. It has given me a melancholy pleasure to perpetuate the 
memory of the assistance I obtained from these gentlemen, by giving their names to the 
only new genera described in the present part. 
Whilst thus I have to deplore the loss of a dear friend, and of two of my most valued 
correspondents, I have to acknowledge obligations to two new contributors of specimens, 
Mr. Samuel Ashmead of Philadelphia, and Mr. A. D. Frye of New York. From Mr. 
Ashmead I have received a collection of the Algae of New Jersey, and a very interesting 
series of those of Key West, including some new species ; the most remarkable of which 
are a new Caulerpa , and a new and very beautiful Dasya. To Mr. Frye I have to 
return my thanks for a collection of the Algas of California, very well prepared, com- 
municated to me through Professor Henry in 1854 ; and to this gentleman I also owe 
an apology for not having mentioned his name in a previous notice of Californian Algae, 
which were sent to me by Captain Pike of New York in 1852, and which I supposed had 
been collected by him. A letter addressed by Mr. Frye to Professor Henry, and forwarded 
to me since the publication of the notice referred to, informs me that the packet of 
Californian Algae attributed to Captain N. Pike was collected by Mr. Frye, and indeed 
formed part of a fasciculus exhibited by Mrs. Frye at the American Institute in 1851, 
and for which she obtained a gold medal. There were several other exhibitors at the 
fair, but Mrs. Frye’s were considered the most rare. “ After the close of the fair,” says 
Mr. Frye, “ I furnished Mr. Pike with a large number of specimens which I collected 
in California. He professed to send them to Professor Harvey of Dublin, stating to 
me that he would send them in my name, and that I should be credited for them in 
Professor Harvey’s work. In looking over the work I found Professor Harvey received 
a collection of Californian Algae, and they were credited to Captain Pike. I was told by 
Mr. Pike and other algologists in New York that mine was the only collection they 
had ever seen or heard of from the Pacific, and I had made the first collection in Cali- 
fornia. This, I think, after making much enquiry is correct, as I cannot find that 
there has as yet been any brought from thence except mine, which I collected with 
my own hands. I exhibited them to the ladies where I was then boarding, at Jones’s 
Hotel in San Francisco : they afterwards borrowed them to show at their parties, and 
sent a gentleman, Mr. W. Ball, to purchase 20 specimens for 20 dollars — which I 
furnished to them, and also spent several days in teaching him how to collect and pre- 
pare them. I should be glad if Professor Harvey could know the facts, as I think he 
would be glad to give me credit for the specimens.” Justice to Mr. Frye compels me 
to give these facts as much publicity as my former erroneous notice has obtained. The 
plants were sent tome by Captain Pike, without mentioning ' any other person, and I 
naturally supposed they had been collected by himself. Nor did I hear of Mr. Frye 
as a collector of Algse, until his letter, quoted above, was received on my return from
