The stems, in some cases fully 18 cm. long, were somewhat reclining 
and the green tips ascending. Except for this difference of habit 
the general appearance of the mass of plants is well represented in 
Bry. Eur. tab. 329. The leaves, however, differ from the illustra- 
tions there given in being narrower, with a decidedly stronger costa 
and a slightly sharper apex. This variation may be caused by its 
exceedingly moist habitat. Dr. Kennedy has compared the Katah- 
din specimens with Husnot's Mus. Gall. No. 331, and with Austin's 
Musci Appal. Suppl. I, No. 509, where it is given as M. compacta 
(Bryum compactum, Bot. Gaz. 2: 111). Habitat, alpine regions of 
the White Mts., common; also mountains of New York and New 
Jersey. 
Pogonatum urnigerum (L.) Beauv. Widely distributed in Europe, 
Asia, Africa and North America. It has been reported from New- 
foundland, Nova Scotia, New Brunswick, Quebec, New Hampshire, 
Vermont, Massachusetts, and numerous other localities throughout 
North America. 
Tayloria tenuis (Dicks.) Schpr. On bones and hair of caribou at 
the edge of the Tableland (G. G. K.). Young and without fruit, yet 
the leaves are characteristic of the genus, and after a careful com- 
parison with specimens from Quebec, Vermont and Alaska, it seems 
safer to place the Katahdin plant here, rather than as a form of 7: 
serrata (Hedw.) Br. Eur., with smaller, less serrate leaves. It cor- 
responds very closely with Macoun's Can. Mus. 141, in areolation, 
size and shape of leaf, but differs in having a more attenuate apex 
and less strongly serrate margin in the upper part. Leaf drawings 
of the Katahdin specimens made with a camera correspond very 
accurately in all details with the illustrations of var. /ezuzs in the Bry. 
Eur. (tab. 285), except that the serratures are only about half as 
prominent as there figured (fig. 6, a.). T. tenuis is reported from 
New Brunswick, Nova Scotia, Gaspé, Greenland, Montana and Ver- 
mont. At least a portion of the Tayloria from Mt. Mansfield (col- 
lected by Dr. Kennedy) appears to be 7. serrata. 
Tetraplodon angustatus (L. fil.) Br. Eur. On nearly extinct re- 
mains of some unidentified animal. Previously reported in New 
England from the White Mts. It occurs in Newfoundland, New 
Brunswick (close to the Maine border), the Adirondacks, Lake 
Superior, Manitoba, British Columbia and northward; also in Eu- 
rope. The leaves of this material vary slightly from some of the
