Limpricht’s Bryotheca Silaesiaca No. 366 cited in his Laubmoose. 
Macoun’s specimens from Arrow Lake, B. C., cited in his Cata- 
logue as O. nudum var. Rudolphianum are also O. cupulatum ; 
and Thos. Howell’s collected in Oregon. Macoun’s catalogue 
notes localities in British Columbia and Baffin’s Bay. This 
would seem to indicate a Northern and Western range for O. 
cupulatum and throw it out of our Eastern. Handbooks, therefore 
it is very desirable that more specimens should be collected of 
this species in order to determine whether it occurs within our 
limits.

Any one who has studied the minute descriptions of Lim- 
pricht’s Laubmoose, and read Philibert’s article on O. Schimpert 
and its allied forms (Rev. Bryol. 33, 1891) will realize that much 
more study must be given to North American specimens before 
we can be satisfied that we understand this species and its alli- 
ances. The group includes, besides what we have been calling O. 
Sallax Sch. O. strangulatum (Beauv.?) Sull. O. Canadense Br. & 
Sch. O. brachytrichum Sch. and two varieties, O. strangulatum var. 
Sull. and O. fallax var. truncatulum Aust. 
The specimens which Philibert recognizes as typical O. Schim- 
peri have a smooth calyptra. American specimens have a few 
short hairs. Specimens distributed as O. fallax Sch. by Limpricht 
as 129b Bryotheca Silesiaca and Rabenhorst’s 125b Bryotheca 
Europea agree with Philibert’s statement that the stomata may be 
both open and closed on the same capsule. No American speci- 
mens that I have seen have the stomata wide open, as described 
by Limpricht in the Laubmoose. Our specimens also differ some- — 
what in the color and size of the plants, the shape of the capsule 
when dry, being less urceolate than European specimens, and the © 
ridges less sharply differentiated and less highly colored, andin  _ 
the size of the spores! But as they agree in all the main charac- : be 
ters, including the very papillose teeth, and especially in the leaves, _ 
it seems a refinement of species to separate them. However, it is |
