Cape Cod, though the nearly allied C. Bazleyi Harv. occurs, in the 
slender, delicate var. boreale, in Massachusetts Bay, and is reported 
by Farlow, N. E. Marine Algae, p. 127, as found by C. B. Fuller at 
Portland. But the plants now in question do not approach ordi- 
nary C. Bailey, much less the var. Zorea/e; they are quite like typical 
C. tetragonum, as found at Newport, Rhode Island. 
The third species, Lomentaria rosea (Harv.) Thuret has hitherto 
been found only from Vineyard Sound to Newport, growing in deep 
water in company with Scinaia furcel/ata (Turn.) Bivona, which has 
practically the same range. The only exception to this is in Har- 
vey, Nereis Bor. Am., part 2, p. 186. In the list of habitats, is 
given f, Portsmouth, N. H., Dr. Durkee. There is no description 
of var. B, but this note; * Dr. Durkee's specimen, noticed above, is 
irregularly branched, the primary stems filiform and straggling, the 
secondary either pinnated or furnished at one side only with pin- 
nules. I have seen British specimens similar to this in ramification.” 
This reference has been generally regarded somewhat as Pike's 
report of Bostrychia rivularis Harv. at the Isles of Shoals, but Miss 
Cherrington’s finding the plant at East Boothbay, July 22, makes it 
quite credible. The specimens are small, hardly 2 cm. high, but 
agree better withthe plates in the Phycologia Britannica than with 
the description of the Portsmouth plant. 
This species was described and figured by Harvey in the Phyco- 
logia Britannica, Pl. CCCI, as Chrysymenia rosea var. Orcadensis, 
with a reference to C. Orcadensis of Harvey’s Manual, ed. 2, p. 100. 
In Pl. CCCLVIII A, of the Phycologia, a figure is given of CArysy- 
menia rosea from the Yorkshire coast, but the distinction of type and 
variety seems not to have been followed by subsequent authors. 
There appears to be no record of it in Europe except on the coasts of 
England and Scotland; its presence among the warm water algae of 
the English Channel, and also at the Orkneys and on the East Coast 
of Scotland, where Ew/Aora cristata (L.) J. Ag. occurs, is paralleled 
by its occurrence in the warm waters of southern New England, 
and on the Maine Coast. 
Itis of interest to note that though Harvey figures British speci- 
mens, he speaks of the name of Chrysymenia rosea having been first 
given, in his herbarium, to specimens received from Newport, Rhode 
Island. 
The occurrence in a comparatively small collection of these 
three species new to Maine, and two of them extending the known
