sparsely wooded hillside, the capsules pointing up-hill towards the south. 
The ground was covered with a blackish film, in fact the whole situation was 
similar to that described by Durand in the Bryologist, 4 :2, 1901. I visited 
the locality again last year and saw them still growing and with an increase 
in number. Dr. James, in his list of the mosses of Delaware Co., gives B. 
aphylla L., but does not mention the exact locality. I would be pleased to 
hear from any one who could give more information as to stations in this 
county. Ezra T. Cresson, Jr.,

Hylocomium triquetrum Beringianum Card. & Ther. 
Mrs. E. G. Britton has called my attention to an extension in range for 
the above moss. - Specimens sent for determination collected by Prof. 
Thomas A. Bonser, were from “ Swan Range, Kootenai Mts., Flathead Co., 
Montana. Aug. 3, 1902. In a marshy spot of an elevated mountain 
ravine.” “ Skykomish Cascade Mts., Washington. In a low marshy spot 
in valley of Skykomish River.” The ecological conditions were apparently 
favorable to its development at these points, growing mixed with Sphagnum 
and in a cool, wet location, at an elevation which would compensate for the 
habitual northern range and account for its southern migration. 
Bryum proligerum (Lindb.) Kindb. 
See the Bryologist, 4 : Jan., July, Oct., 1901; also 5 : Sept., 1902. On 
June 10, 1903, the bed of B. proligerum , at Chilsori Lake, Essex Co., N. Y., 
had extended from its original size of last year, of a foot square, to about 
three feet or fully three times its surface. It began to fruit June 26th, and 
continued to develop both gemmae and capsules till the end of the observed 
season. Sept. 20th. By this time it had extended along the bank for a dis- 
tance of six or eight feet. A. M. S.
