shortly excurrent, and by the total lack of peristome; at least, all the cap- 
sules we have been able to examine do not show the slightest trace of this 
organ. The pellucid border of the leaves shows some relationship between 
D. systylioides Ren. & Card. and D. Portert James, but the latter has a much 
narrower capsule with a highly conic lid not adhering to the columella, and 
the peristome and annulus are well developed.

Idaho: Cedar creek, Latah county, on ground (L. F. Henderson, 1897). 
This moss, received from Mr. Henderson only in very small quantity, 
seems a miniature of B. favifes BS., from which, besides in its small size, it 
differs chiefly by the lid as long as the capsule or even longer. By this char- 
acter, as well as by the form of the leaves, it resembles also 7richostomum 
dicranoides Sch. (T. macrostegium Sull. Icon. Suppl. 35, £7. 22) from Central 
and South America and the Antilles, which has been also recorded from Ala- 
bama ; but this last species has the beak of the lid thinner, the leaves larger, 
broader, denticulate above, a less opaque areolation of larger and more dis- 
tinct cells, and the peristome less twisted, with a shorter basilar membrane.
