p. 59, as to New England localities; Hervey, Sea Mosses, p. 74; 
Farlow, Marine algae of New England, p. 103, and of various papers 
and lists, but not S. vulgare Agardh, as is pointed out by J. G. Agardh, 
Sp. Sarg. Austral., p. 120, 1889. S. natans is occasionally washed 
ashore from Vineyard Sound south; it follows the course of the Gulf 
Stream, and in times of strong, long-continued easterly winds, consid- 
erable quantities may be found from Gay Head to Nantucket Shoals. 
I have picked up a much battered fragment at Menauhant, in the 
eastern part of Falmouth, Massachusetts, and know of no record of 
its coming ashore farther north. S. fluitans is occasionally found with 
it. J. G. Agardh, Sp. Sarg. Austral., p. 106, writes, “radice instruc- 
tam et fructiferam ad oras Americae foederatae lectam habeo, in 
rupibus extra New Foundland.” I agree with Bérgesen, Sp. Sarg., p. 
12, “That the plant should have been found ‘radice instructam’ i. e. 
attached, near Newfoundland seems so unlikely that I deem it un- 
worthy of consideration.” Incidentally it is an interesting question 
geographically what part of the United States is on the rocks beyond 
Newfoundland. I have a specimen marked “In oceano prope Terre- 
Neuve fluitantem legit Lesquereux.”” A change of labels between this 
or another specimen of the same origin, and some attached plant, may 
have been the cause of Agardh’s statement. Durant ! notes finding 
it in New York Harbor, and includes it among the specimens accom- 
panying his book. These specimens are of the typical form. It drifts 
ashore on the New Jersey coast,? and though there are practically no 
records of algae from Atlantic City, New Jersey to Charleston, South 
Carolina,’ in all probability it grows more frequent as one goes south. 
Perhaps the best place for the study of the pelagic Sargassum is the 
Bermuda Islands. On the voyage from New York one begins to see 
the floating patches and strips of the alga within 24 hours after leaving, 
and they continue in sight the rest of the voyage. They are every- 
where in sight as one sails or rows about the islands, and windrows of the 
Sargassum may be found about high water mark on lee shores, like the 
windrows of Laminaria on the rocky shores of New England. The
