In other swamps of the region the formula was repeated which pre- 
ceded my discovery of Arceuthobium, but the charm seemed to have 
vanished, for I was unable to induce more of the mistletoe, or any 
Scolopendrium or other plants which I thus sought, to appear before 
me. Later in the week, however, I drove through a spruce-swamp 
several miles south of Fort Kent, in the Swedish town, Upsala, and 
there several of the trees were dying from the effect of the little mis- 
tletoe. "These stations are interesting as giving a considerable north- 
eastern extension of the recorded range of the parasite. 
The French and English people at Fort Kent, to whom I showed 
my treasures, expressed little surprise, for, according to them, branches 
bearing the plant are frequently brought in by woodsmen. One woman, 
whose observations upon the native plants are generally accurate, stated 
that at a grand mid-winter ball at Tadoussac, at the mouth of the 
Saguenay, she had seen many of the women wear in their hair the 
twigs covered with the purplish brown íruit. Whether they realized 
that the little plant was a mistletoe and whether it had with them the 
traditional significance of the European plant, she could not state. —

A FEW species of marine algae, new to this region, have been 
noticed lately ; they are mostly inconspicuous plants, as is to be ex- 
pected in a region whose marine flora, not exceptionally rich in species, 
has been so long studied ; and it is probable that of such minute spe- 
cies, many still remain for future discovery. 
Phormidium persicinum (Reinke) Gomont, with extremely slender 
filaments, barely 24 in diameter, forms a thin, pink film on shells, 
mostly on the Spirorbis which is often attached in great abundance to 
larger algae, especially Fuci, Laminariae, etc. In the present case the 
Spirorbis was on Rhodymenia palmata, found floating at Nahant, Mass., 
in June, 1899. The species was described by Reinke, as a Lyngbya, 
in the Algenflora der Ostsee, p. 91; the description is reproduced, 
under Phormidium, at p. 184 of Gomont's Monographie des Oscillariées. 
Chlorochytrium Schmitzii Rosenvinge, a green alga of very simple 
structure, occurs among the erect filaments of such algae as Cruorta 
pellita, in which it was first found by Rosenvinge ; it is described and
