DESCRIPTION OF SPECIES. PP. 39 



ville, and at West Union, in the roof-sliales of tlie Waynes- 

 burg Coal, and at Bellton, 400 feet above this coal bed. 

 From West Union we have some very fine specimens of the 

 plant, showing a stem bearing many long leafy branches. 

 It is exactly like Gutbier's species. 



Annularia longifoUa, Brongt. 



This species, as previously stated, ranges throughout the 

 entire thickness of the strata above the Waynesburg Coal. 

 It becomes more abundant towards the top of the series, 

 where so many other plants, common at lower horizons, 

 have disappeared. 



Habitat. — Roof -shales of the Waynesburg Coal, at Cass- 

 ville. West Union, and throughout the Upper Barren Meas- 

 ures. 



Annularia sphenophylloides^ Ung- 



This well marked species has been seen at only one local- 

 ity and horizon, and that was in the roof shales of the 

 Waynesburg Coal, at Cassville, West Virginia. 



Annularia radiata, Brongt. 



At Cassville, West Virginia, in the roof-shales of the 

 Waynesburg Coal, we find a very delicate species of annu- 

 laria which very much resembles A. radiata Brongt. It is 

 smaller, and the leaves are nairoAver, but the difference is 

 not sufficient to separate the two. 



Annularia minuta^ Brongt. 



This well marked little species was seen in immense 

 quantities in the roof shales of the Washington Coal, near 

 Little Washington, Penna. The leaflets are very short, 

 and the joints of the stem seem to be swollen at the points 

 of attachment. Though not seen in West Virginia, the 

 nearness of the locality in Pennsylvania to tlie West Virginia 

 localities, entitles it to mention here as throwing light upon 

 the flora of our Upper Barren Measures.
