Plants of the Pittishurgh series {Lower Barren Measures) 

 are comparatively rare and unstudied. A bed 20' beneath the 

 Pittsburgh coal at Wheeling, V^a., has been explored with the 

 following results : Neuropteris hirsuta^ rarinei'vis^ acu- 

 tifolia^ flexuosa, loschii^ grangevL — Sphenopteris -furcata^ 

 minutisecta (a new species by Fontaine & White.) — Pe- 

 copteris pluckeneti. hucMandi^ spinulosa^ candolleana^ notata^ 

 dentata {plumosa)^ pteroides. Alethopteris aquilina & new 

 species allied to gigas. — Lesqueropteris moorii. — Odontop- 

 teris new species allied to ohtusiloha. — Annularia longifolia^ 

 sphenophylloides. — Cordaites hor assif alius > — Sphenophyl- 

 lum Miculme^ trifoliatum — Asterophyllites (near) equise- 

 tiformis. — Phachophyllum Miciforine. — Calamites cannq- 

 forrms. — Syringodendron pescaprioli, — Many fruiting pinni- 

 cles of IBecopterids ; even several fruiting Neuropteris hirsuta ; 

 fine fruiting Alethopteris aquilina^ Note. The L, moorii 

 elsewhere belongs to higher horizons. (Report PP, p. 20.) — 

 Fine stems (and sometimes casts) are commonly to be found 

 in the Mahoning sandstone beds (K3, 306). They crowd 

 some of the layers on Laurel Hill run, St. Clair, Westmore- 

 land. K3, 110, 175. — There is a plant bed in the 50 foot sand- 

 stone, 80' under the Pittsburgh coal, at Carman's, on McGuires' 

 run, Washington county, K, 295. — XIV. 



Plants of the Monongahela series ( Upper Productive Coal 

 Measures) belong to the great fresh- water limestone age. They 

 have been studied by Fontaine & White as chiefly collected 

 from the roof shales of the highest large bed of the series, the 

 Waynesburg Coal^ and figured and described in their Report 

 PP, 1880 : — Equisetides rugosus Schimper, elongatus F. &
