bus apice latioribus obtusiusculis, theca elliptica plicata, operculo 
conico. acuminato, peristomio dentibus bigeminatis 8, ciliis aequi- 
longis angustis 8, calyptra breviter appresse ramentosa.” 
Now as Venturi says, in-the Revue Bryologique, our speci- 
mens of 153 agree with this description, and the erose margins of 
the upper part of the leaves is due to the prominent papillz. 
Therefore unless Mitten can prove it to the contrary, I will man- 
tain the synonymy as given above. og 
Prof. Macoun in his Catalogue says he has “never observed a 
species of Ulota that grew indiscriminately on rocks and trees, and 
therefore proposes to place U. Americana at Hell’s Gate, and 
hence a rock species,” but he makes the same mistake that 
Limpricht in his Laubmoose does, and refers to it U. Hutchinsie 
as well, citing also Drummond’s No. 147, evidently without critic- 
ally comparing the specimens. Now U. Hutchinsie, though usu- 
ally a rock species does occasionally grow on tress, according to 
Limpricht, 1. c., and we have specimens from E. Faxon collected 
at Brookline, Mass., on trees, as also from A. Commons, near 
Wilmington, Delaware. Austin collected it on trees near Closter, 
and last summer I sent to Venturi specimens from the summit of 
White Top Mountain, Virginia, that grew in dense spruce woods 
both on rocks and trees, and he pronounced them the same as 
European Hutchinsie, though at the time I did not feel satisfied 
to call them that species.

(1892). 
In Macoun’s Canadian mosses No. 1 15 was distributed as U. 
Americana, but later in the Catalogue it was described as a new 
Species, U. scabrida, Kindb., on acconnt of its densely papillose 
leaves. These specimens in our set are very papillose, with erose_ 
Margins, and they seem to me to agree with Drummond’s No. 153, 
a8 nearly as young U/oras will agree with older specimens of the 
Same species. Furthermore the specimens agree with Kindberg’s 
description as far as it goes, though I cannot assent to his com- : : si 
Persons, for he seems to. me to have aud the reverse of what he 
Should have said, when he states that. they resemble : U. erispa ‘ 
more than U. curvifolia, and are not much allied to the
