OF PACIFIC COAST MOSSES. 
237. H. Stokesii, Turn. 
Hab. on shaded ground and rocks, very common, Lol., Diy. ; Vancouver

238. H. Oreganum, Sulliv. 
Hab. in woods, on decaying logs or on the ground, Bol., Drew., Big.; Puget 
Sound, Oregon, U. 8. Wikes’ Exp.; Vancouver Island, Wood. 
27. RYNCHOSTEGIUM, Bryol. Kur. 
239. H. rusciforme, Weis. 
Hab. in a rivulet near Mt. Diablo, sterile, Dr. Hillebrand, Bol. 
38. THAMNIUM, Bryol. Eur. 
240. H. Bigelowii, Sulliv. 
Hab. on shaded rocks, in canons, Big., Bol., Brew. 
241. H. Neckeroides, Hook. 
Hab. Vancouver Island, Wood. 
According to Mitten, we have, in the United States, in this division of the Hyp- 
nacee, H. Neckeroides, Hook., found by Drummond in St. Louis; H. alopecurum, sent 
from Boston, and H. Alleghaniense, Mull. Though we have examined, with Mr. Sulli- 
vant, a great number of specimens, either collected by ourselves or sent from various 
points of the United States, we have never been able to find any species different from 
that of H. Alleghaniense, Mull., which differs from H. alopecurum by the inflorescence 
only. This 7. Alleghaniense is the same moss as No. 119 of Drummond, H. Neckeroides, 
quoted by Mitten. And as the male flowers are rarely found on fruiting plants, in- 
complete specimens are often taken for 7. alopecurum. I believe, therefore, that these 
three species, quoted by Mitten, are, for American specimens, referable to the same 
H. Alleghaniense, Mull. H. alopecurum from Europe, and H. Neckeroides, Hook., from 
New Zealand, are indeed different, but not yet found in our country.
