the low, rolling country which sinks gradually to the level of the 
Hocking valley several miles distant. It seems quite probable 
that the drainage above the constriction was formerly carried to 
the northward into Hocking, but the region was not studied 
closely and the course of the old outlet is undetermined. 
LIST OF THE MOSSES OF CUYAHOGA AND OTHER 
COUNTIES OF NORTHERN OHIO. 
Edo Cl.a-assen. 
This list is the result of the author’s moss-collecting excursions 
during the last eight years ; it may, consequently, be expected to 
fairly represent the moss-flora of Cu 3 'ahoga county, as also the 
greater part of that of the surrounding counties. Manj’ species 
were found many times in the same countjq others but once in 
the same county or even in all the counties together, and while 
many may be new to the flora of the respective counties, several 
are new to the State, as, for instance, Dicranella curvata, Hypnum 
ochraceum and M^iium Drummondii. Although almost all the 
species could be and were collected in the fruiting condition, 
there were several that were never seen with sporophj’tes, as. for 
instance, Eurynchhim Boscii, Hylocoiniuvi splefidcns, Hypnum 
Sc/ireboi and Myurella Carey ana. It ma}’ be added, that all the 
species enumerated below are represented in the author’s herba- 
rium, often in several or many packages from the same count}', 
and that the list-names of the mosses are those accepted in 
Le-'quereux «& James’ Manual and in Barnes’ Ke}'s.
