the most grateful reward of my labours ; and now that he is removed, my interest iu 

 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. Frte of New York. From Mr. 

 Ashraead 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 Algte 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 Algte, 

 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 Algte 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 to me 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
