 perichiEtium distichous, the lower leaves shorter, the upper and 

 inner ones very long-acuminate, obscurely serrate at the apex : 

 calyptra large, cuculliform, si^lit three-fourths of its length, 

 tipped with a long slender flexuous awn as long as the ca\yi)tra :

Hab. Not rare on the shaded vertical face of sandstone rocks in the 

 coal measures of Middle Ohio and Kentucky, sterile. Found fertile only 

 (July, 1883) in similar situations on rocks of the Potsdam sandstone in 

 the dells of the Wisconsin Eiver near Kilbourn City, Wisconsin, by Miss 

 Elizabeth G. Knight. 



Two species only of this genus are known. The second, E. Savnteri, 

 Husnot (Revue Bryol. v. So), is from Japan, and has also been found in 

 fruit. It differs merely in the shorter and broader stem-leaves, abruptly 

 round-truncate and denticulate at the apex, and cuspidate by the excurrent 

 rough thick pointed costa. The pedicel is of the same length and char- 

 acter; the deoperculate capsule is oval. The calyptra and the operculum 

 have not been seen.
