 "^ '^P^y port, 1882, page 80, who groups 

 *^ it withZ. rimosum^ Z. worthenii^ 

 and the European Z. volkmannianum^ as confined to the Suh- 

 carloniferous ; his plate 17, fig. 4, 4 a, gives the form of its 

 scars. — Conglomerate or Sub- conglomerate formation. See I. 

 G. White's Report Q3, Q4, for its occurrences in N. W. Penn- 

 sylvania. XII — The Sharon coal bed between the middle and 

 lower divisions of the Gonglomerate has roofshales which are 

 often quite rich in fossil plants ; for example at the Snyder 

 Goal Go's shaft in Mercer Co. Here the 35 feet of shales are 

 crowded with them ; and of several species of Lepidodendra. 

 Other excellent localities are the Morris Go's shafts ; and Oak- 

 land mine No. 1. — Lesquereux says that lep, brittsii^ found in 

 the Glinton coalbed of Missouri, is typically allied to lep.volk- 

 m.a7inianum ; and in Pennsylvania this last is abundant in the 

 sub conglomerate shales. 



Lepidodendron carinatum. Lesq. Geol. Penn. 1858,

 ends and keeled; found 

 in the low anthracite 

 coal beds at Garbon-

 1880, page 386. There 

 was at that time a 

 specimen of this species 

 in the cabinet of Prof.
