were drawn. Figure b. represents the teeth shorter, and with 
fewer segments than the original; they are erect when dry. The 
mouth is bordered by several rows of smaller cells, and there is a 
hyaline annulus. Figure d. also is poor, because the type has the 
neck defluent, and figure f. because the calyptra is lobed, distinctly 
striate, and is not nearly as wide as represented, its base clinging 
close to the base of the capsule, which, however, is immature. I 
compared the specimens with O. 7¢xanum, number 187 of S. & L. 
Musci Bor. Am., ed. II., 1865, and with the plate of the latter in 
the Icones. The leaves are very similar, being carinate, with 
strongly revolute margins, the apex acute, and often plane for a 
short distance above the point where the vein disappears, or the 
vein may be percurrent. The base of the leaf in O. Zevanum is 
narrower and more decurrent at the angles, and the margins are 
revolute to the base; the vein is broad and thick, often brown, 
and the basal cells are yellow, oblong or sinuous. 
It seems probable that QO. Douglasti must be masquerading 
under another name in our herbaria, but owing to the imperfect 
condition of the type, it would be difficult to prove this.

When studying the mosses collected by J. B. Leiberg, I was 
permitted by Dr. Watson to examine the type of this species, 
Which has only been collected once, by Bolander at the Falls of 
the Yosemite. It is closely allied to O. devigatum, Zett., and the 
Similarity will be apparent if the figures of both are compared. 
O. levigatum is described as a variable species by Venturi, and is 
much more common in America than the Manual would indicate, 
as it cites only one locality in Western Nevada (Watson). Our 
Specimens from this locality, No. 1404 Watson, are not this spe- 
cies but seem to be O. Watsoni. Macoun collected O. evigatum 
at the Cascades at Yale in 1875, and Austin described it as O. 
Macounii, n. sp. (BULLETIN, vi. -343, 1879), but subsequently re- 
ferred it to O. Kingianum. It has recently been distributed in 
Macoun’s Canadian mosses as No. 454, and has been collected in 
two localities near Lake Pend. d’Oreille by Leiberg, showing 
mixed with it forms with a broader pyriform capsule and shorter 
Seta, as in O. Kingtanum. More ‘Study and sees is desirable of 
_ these four species. ;
