One of these two species of Chætospora may be considered the Antai-ctic representative of thè Sehoemis nigricans
of Europe. Neither of them appears to inhabit a high south latitude, though the 0. Antarctica, ascending to au
elevation of 2,000 feet in South Chili, might have been expected to grow at the level o fth e sea iu Fuegia.

Tlie Carpila schanoides of tbe hibs of Fuegia, and tlìe C. alpina, Br„ of the loftier mountains of Tasmania, are
two closely-abied representative species, both apparently very rare and local plants. 0. alpina is replaced frirtliei-
north, m Austraba, by the C. deusta, Bi-., a native of the colony of Port Jackson, but hitherto no South American
species except the one here described has been noticed. These three form together a very distmct gi-oup, as
Mr. Brown has indicated (Prodi-, p. 230).

Dr. Boott has kindly favoured me with the range of this species, which is so wide in the northem hemisphere
that we should quite expect that it will hereafter be found along the chain of the Cordillera. Commencing in
Greenland ou the east, it crosses to Unalaschka on the west by Cumberland House on Bear Lake, and thence runs
soutli along the Rocky Mountains. In Europe it has hitherto been found in Lapland only.

The present, Dr. Boott remarks, is decidedly the European C. curta, one Ealkland Island specimen alone, out
of very many, differing from the others in having ten spiculæ, the average number being six to eight.
The geographical distribution of this species is 4'ery wide, for it inhabits aU Europe from the latitude of
Lapland, where, according to Wahleiiberg, it is excessively common, to the Mediterranean region, wliich it does
not enter. In Arctic iVmerica again it is abundant, extending in the United States as far south as New York.
