This species, in habit, resembles E. streptocarpa, but the capsule and the peristome are very different, nearly as in the true E. longipes, Mitt., by Lesq. & James considered as E. procera, distinguished by the twisted capsule and the double peristome.

Crevices of rocks summit of Mount Queest, Gold Range, B.C. Alt. 6,500 feet. (J. M. Macoun.)

(370.) E. longipes, Mitt. Journ. Linn. Soc. VIII. 29; Canadian Musci, No. 474.

Stem about 2 cm. high or lower, branched and radiculose. Leaves erect-patent, narrow, sublingulate, revolute all around, short-acuminate, obtusate or sub-acute, without a hairpoint; the lower decolorate brown, incurved, the upper green, irregularly crisped; lower basal cells hyaline.

Differs from Encalyptra leiocarpa principally in the stem being shorter, the leaves short-acuminate or subacute, costa very rough, narrowed from the base, the calyptra regularly laciniate, very rough and subspinulose above, blackish to a third of the apex, the capsule included. The authentic specimens of Drummond were consulted in the collections of Dr. C. Mueller.

Quite common along the edge of the torrent at Hector, and on rocks in the "Dry Canon," discharge of Devil's Lake, Rocky Mountains. (Macoun.)

(373.) E. Streptocarpa, Hedw.; Lesq. & James, Mosses of N. America, 183; Canadian Musci, No. 135.

(374.) E. cucullata, C. M. & Kindb. (n. sp.); Canadian Musci No. 491.

Monoecious. Leaves cucullate, the perichetial ones long-acuminate acute with a long hair-point; costa percurrent, red only at the base; calyptra papillose all around.

This species is nearly allied to E. procera which has the upper leaves, also the perichetial, obtuse or subacute, the costa in most? leaves red for the whole length.

On earth along the west bank of the Columbia River, at Revelstoke, B.C., May 9th, 1890. (Macoun.)

(363.) E. vulgaris, Hedw. White Bay, Newfoundland. (Rev. A. Waghorne.)

(947.) E. Alaskana, Kindb. (n. sp.)

Differs from Encalypta longipes principally in the capsule being striate and not apophysate, the peristome brown-red, appressed to the mouth in a wet state, the costa of the leaves nearly smooth. Monoecious. The lid of the capsule is obliquely rostrate. Calyptra not found. Encalypta longipes has an apophysate and quite smooth capsule, red peristome, always erect, and the costa very rough.
