6 COLLINS AND HERVEY. 



Hamilton, has kindly allowed us to refer to an interesting collection 

 she has made, and we are also much indebted to her for information 

 as to stations of some of the rare species. In 1882 Miss Kate Peniston, 

 now Mrs. Matthews, sent one of us some algae from the Harrington 

 Sound region; comparatively few specimens, but including some of 

 much interest. Several species from Bermuda are recorded by Dr. 

 M. A. Howe in his papers in the Bulletin of the Torrey Botanical 

 Club, and some of them have been distributed in the Phycotheca 

 Boreali-Americana. An occasional specimen from some other col- 

 lector will be noted in its appropriate place. Collections were made 

 by ourselves in the years from 1911 to 1917, during which period one 

 or the other of us has been in Bermuda rather more than half of the 

 time, collecting in practically all parts of the islands and in all months 

 except June. While future additions are of course to be expected, 

 we think that the main characters of the algal flora are fairly settled, 

 and the greater part of the species determined. A special effort has 

 been made to distribute in the Phycotheca Boreali-Americana as full 

 a representation as possible of Bermuda algae, and fascicles XXXVIII, 

 XXXIX, XLI, XLII and XLIV consist entirely of specimens from the 

 islands. 4 We have distributed in this way every species of which 

 sufficient material was available. 



A number of new species are described and figured in the following 

 pages, and we have tried to give all details of value in regard to them. 

 In case of other species, whenever we could add anything to previous 

 knowledge of them, we have tried to do so, but no full descriptions 

 have been given except for new species, varieties etc. Concise keys 

 however, have been furnished, and we think will prove useful. We 

 have been rather full in notes as to character of station, as this is 

 something sadly lacking in many floras. Exact localities have been 

 given, for the aid of future students, and the date of collecting is 

 given by month, but it has not seemed necessary to give the year. 

 No full synonymy is given, but pains have been taken to give for 

 each species the proper name under the international rules; the ori- 

 ginal name, if published under another genus; and when possible 

 reference to a good figure. Whenever specimens from Bermuda have 

 been distributed in the Alg. Am.-Bor. Exsicc. or in the P. B.-A., 

 reference is given by number. Other references are given in cases 



4 A set of these fascicles will be found at the Bermuda Agricultural 

 Station, to whose Director, Mr. E. J. Wortley, we are indebted for many 

 kindnesses during our visits to the islands.
