—G. U. Hay and A. H. MacKay. (Bull. Nat. Hist. Soc., 
_New Brunswick, vi., pp. 62-68.) 
This comprises eighty-four species, collected mainly by the 
authors and Prof. Fowler. Specimens of Laminaria longicruris, 
De la Pyl., were collected, measuring twenty-eight feet in length, 
and it is stated that Prof. Lawson, of Dalhousie College, used its 
hollow stipes in place of rubber tubing, when this could not be 
obtained at once, and found them to answer well for the conduc- 
tion of gas. Dulse, Rhodomenia palmata (L.), Grev., is exported 
from St. John and other places on the Bay of Fundy, to the 
amount of 100 tons a year. A/aria esculenta, Grev., another 
edible species, occurs at Halifax and Grand Manan. 
Aphylion as a root Parasite-—Thos. Meehan. (Proc. Acad. Nat. 
Sci. Phila., 1887. Advance sheets.) 
Mr. Meehan reports the growth of Aphyllon fasciculatum, 
Torr. and Gr., on the roots of Pelargonium zonale in the hot- 
houses of Mr. Morris, of Des Moines, Ia. The whole period of 
life of the parasite did not exceed three months.

Californian Manzanitas.—C. C. Parry. (Bull. Cal. Acad. Sci., 
ii., pp. 483-496; reprinted.) 
This paper is ‘a partial revision of the Uva-ursi Section of the 
genus Arctostaphylos, as represented on the North American 
Pacific Coast.” Dr. Parry distinguishes as new species, A. Man- 
sanita (the A. pungens of various authors, but not of HBK, 
which, he says, is extra limital) ; A. viscida, (separated from A. 
glauca, Lindl.); A. Stanfordiana, described as of remarkable 
beauty ; A. insularis, Greene, from the island of Santa Cruz, 
formerly listed by Prof. Greene as A. pungens, and A. Pringlet, 
from Arizona, named for the collector and distributed among his 
collections of 1885 as A. tomentosa.
