DRUMMOND’S NORTH AMERICAN MOSSES, 667 
from the true Racomitrium fasciculare, Brid., and belongs 
perhaps to Racom. Canadense, Brid. 
137. Tortula humilis, is Desmatodon flavicans, and the 
same form which is distributed under No. 114, as Didymodon 
oblongifolius. 
142. Tortula tortuosa var. inclinata (Barbula inclinata 
Schwegr.), is B. tortuosa var. compacta cæspitosa, foliis et 
capsulis brevioribus. 
144. Tortula subulata, is Barbula mucronifolia Bryol. 
Europ. 
145. Tortula suberecta nov. sp., is Desmatodon obliquus 
Bryol. Europ. An extremely rare plant, for which only two 
European localities are recorded. 
150. Orthotrichum affine var. pumilum, is O. strangulatum 
Schwægr. 
149, 151. Orthotrichum affine var. capsulis exsertis, is more 
nearly related to O. patens : but differs, however, from this 
species remarkably in its smaller capsules, which are longer 
pedunculated, and in the rusty red-coloured teeth of the 
peristome :—it is without doubt a new species, for which we 
propose the name O. Canadense. No. 149 differs from 151 
only in having longer stems, 
154. O. striatum Hedw. appears to be O. fastigiatum. 
The capsules are, however, partly too old, partly too imma- 
ture, for determination. 
155. O. elegans, differs in no respect from O. speciosum 
Nees. 
157. O. obtusifolium, belongs partly (and principally the 
fruited specimens) to O. Rogeri var. foliis acutiusculis, calyp- 
tra subpilosa. 
159. Neckera sericea Frol., is Anomodon (Pterogonium) 
repens. 
160. Neckera cladorhizaus. A is rightly doterinined; B 
belongs, however, to N. seductrix (Anomodon). 
162. Neckera Menziesii. A remarkable species, but ths 
specimens are sterile. 
163. Neckera viticulosa. The same variety whioh Heaw.
