38 PP. REPOKT OF PKOGUESS. FONTAINE & WHITE. 



SpJienopliyllum tenuifoUum, Sp. nov., PI. I, Fig. 9. 



Stem slender, furnislied with rarher remotely placed 

 whorls of six leaflets ; leaflets, linear-cuneate, six- toothed 

 at the end, without lobes ; nerves, single in the base of 

 the leaflet, forking three times above, so as to send a branch 

 into each tooth of the leaflet. 



This form is so well marked, and different from any spe- 

 cies hitherto described, that we are compelled to assign it 

 speciflc value. It occurs often by itself, with constant 

 features ; hence it cannot be an abnormal form of some, 

 other described species. It is a little like Germar s S. an- 

 gustifolius. There is no connecting link to unite it with 8. 

 denslfollaiLim. 



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

 ville and West Union, West Virginia. 



BplieMopliyllibm loiujifolluin, Germar. 



This species is not rare in the roof shales of the Waynes- 

 burg Coal, at Cassville, and West Union. Some of its leaves 

 have been seen which were more than an inch in length. 



SplieuopJtyllicm obloiigifuUwm^ Germar. 



This is another species which is not uncommon. It is 

 seen in great quantities in the shale parting which supports 

 the roof coal of the Waynesburg bed at Cassville, West 

 Virginia. Though often associated with ^S". Jillculmis, it 

 always presents an entirely different aspect, and they are 

 without doubt different species. 



Annulaeia, Sternb. 



This genus is well represented in the Upper Carboniferous 

 strata, ascending into the highest beds, where Annularia 

 longifolia., Brongt, is one of the most common plants. The 

 following species have been seen : 



Annularia carinata, Gutb. 



This is a verv abundant form, and has been seen at Cass-
