Sullivant’s Muscology. 79 
No. 214, Andrea Rothii, is here first published as an Ameri- 
can moss; but we believe that Scuweinitz had found it in the 
mountains of Virginia. 
Passing to the Hepatice, No. 220, Plagiochila porelloides, Lin- 
pens., is here first made known in fruit, and with amphigastria, 
which had been overlooked. 'The proposed new species of the 
genus we have already given. No. 227, Jungermannia Taylori, 
Hoox., collected by Mr. Oaxes in New England, is here first enu- 
merated as American. No. 260, Radula complanata, var.? sive 
n. sp.? and No. 261, R. pallens, are in the same case. No. 271, 
Frullania Hutchinsia, var. foliis subintegerrimis, is a striking 
variety of a very rare plant, not before found out of Ireland. It 
was detected in moist rocks at the Mountain Cataract of Pigeon 
River Falls, along with Hookeria lucens and (on the dried sum- 
mits of the rocks) Andrea Rothii. No. 274, Lejeunia cuculla- 
ta, N. ab E., 275, L. calearea, N. ab E., and 276, L. minutisst- 
ma, Dumort., are likewise new to North America. Nos. 289, 290, 
Notothylas ; this interesting genus will probably soon be illustra- 
ted by Mr. Suniivanr. 
This work lays the foundation for the study of North Ameri- 
can Muscology among us. We now only wait fora Species Mus- 
corum of the United States, to facilitate the study of the family 
for students generally, and this we trust Mr. Suutivant will not 
be long in giving us. 
The view of these beautifully prepared specimens as here pre- 
sented to us, brings back to recollection their appearance as they 
grew in their fresh native wilds, and vividly recalls the varied in- 
cidents of the arduous but delightful journey during which they 
were principally collected,—the laborious mountain-ascents, the 
_ night bivouacs, the healthful woodland life and primitive fare, and 
the many amusing adventures, of a tour which extended along 
the principal length of the Alleghany Mountains, through much of 
their most picturesque scenery, and through regions which abound 
with the choicest botanical t which the country affords. A 
cursory indication of the particular routes pursued will not be 
deemed superfluous, since it is recorded by our author only in 
the general terms of the title page. The expedition, which had 
for its principal object, on the part of one of its members, the col- 
lection of live plants for the Cambridge Botanic Garden, may be 
said to have commenced, late in August, 1843, in the mountains
