May, 1904] List of Mosses. 157 



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 Claassen. 



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 Cuyahoga county, as also the 

 greater part of that of the surrounding counties. Mau)^ species 

 were found many times in the same county, 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, fc!' instance, DicrancUa airvafa, Hypinim 

 ochraceitm and Mnimii Dnnnunvidii. 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, Euryuc/iiinii Boscii, HyloconiiiDU splcndens, Hypniiiii 

 Sc/irebeii Q.\\d Myitrclla Cany ana. It ma}^ be added, that all the 

 species enumerated below are represented in the author's herba- 

 rium, often in several c many packages from the same count)', 

 and that the list-nam'^s of the mosses are those accepted in 

 Le^quereux & James' Manual and in Barnes' Keys.
