adds one authentic record to this small group : Porphyropsis coc- 

 cinca, not previously known from south of New Hampshire. There 

 is no reason, on the basis of the other additions to the Long Island 

 flora, to change our conception of its general character. 



Records of Long Island, N. Y., marine algae are not very 

 numerous, nor, for the most part, are the studies particularly 

 thorough or extensive. A very few old local lists, mention in 

 some more general ecological studies, and a few uncritical com- 

 pilations, make up the bulk of the sources of information. Our 

 earliest records specifically including Long Island algae and those 

 of New York Harbor are those of Durant (1850) and Hooper 

 (1850). Durant's volume, in effect an exsiccata, was prepared in 

 a very small number of copies and not widely circulated ; conse- 

 quently it did little to affect the early study of algae of the area. 

 Hooper rarely gives a more. exact record than New York Bay or 

 Long Island Sound, but probably under the latter dealt with some 

 Long Island specimens. Harvey (1852-58), in preparing his 

 Nereis, is likewise somewhat vague, and generally by inference 

 refers to mainland stations when mentioning Long Island Sound, 

 but does specifically designate places on the island. Farlow in 

 1881 mentions certain Long Island stations, and later (1893) a 

 very few others. Pike (1886) is the first to deal in any large way 

 with algae of this area, and his paper gives a long list well fur- 

 nished with definite locations at which the algae were collected. 

 Jeliffe (1904) offers but two additions. Johnson and York (1912) 

 first gave descriptions of the relation of marine algae to their sub- 

 strata and to other vegetation on "Long Island, a subject also 

 touched by Transeau (1913). Howe, although for many years 

 living near New York and no doubt with occasion to note the algae 

 of Long Island, appears to have published but one paper on them, 

 in which (1914) he gives the occurrence in winter of quite a few 

 species. Burnham and Latham (1914, 1917) give a considerable 

 algal list without, however, many exact localities. Grier (1925) 

 adds several station records, and includes by compilation the earlier 

 ones falling within his territory. Since that time, so far as the writer 

 is informed, there has not been any addition to the published flora 

 of the marine algae of Long Island, although citation of the pres- 

 ence of the various marine species on the island was attempted in 

 the writer's volume on Marine Algae of the Nortlieastern Coast.
