Vers. 1, p. 23, PI. 11, fig. 2, 3, 4. 



It is not rare in the shales of the coal at Morris, in good, well characterized 

 specimens. 



LEPIDOPHLOIOS PROTUBERANS, Sp. nov. 



PI. xxvi, fig. 1 and 2. 



STEM arborescent with cicatrices somewhat distant, separated 

 by thin, undulating, continuous wrinkles bordering the cauda; 

 cicatrices double; the upper part or leaf scar is rounded up- 

 wards and downwards, obtusely acute on both enlarged sides, 

 marked by three vascular points, the middle of which is 

 capped by a small, half round dot; the lower part like a broadly 

 oval-rhomboidal wing, has both sides curving downwards as 

 a prolongation of the borders of the leaf scar, and abruptly 

 bent into a long pointed cauda, fig. 2. The wing is marked 

 above the middle and under the leaf scar by a semi-lunar up- 

 raised scar. The cicatrices are generally deeply immersed in 

 the stone, and their outlines rarely discernible. They are 

 often covered with a coat of thick carbonaceous matter, and 

 their center marked by a prominent nose-like gibbosity. 

 In the shales at Morris ; collected by Mr. S. S. Strong.
