PLATE V. 



AsterophylSites tubercuSata. 



Sternb. Sp. (?). 



Although no locality is given with the original draw- 

 ing, it is probable that the specimen represented came 

 from the rich plant-shale above the Bensham seam, at 

 Jarrow. 



It is an Asterophyllitic stem, in which the nodes are 

 obscurely marked, except on one side, by the leaf -bearing 

 branchlets (as Lindley and Hutton considered them to 

 be), or fructification spikes (according to Geinitz and 

 Schimpee). It closely resembles the Annularia latifolia of 

 Professor Schimpee, but according to our rule we have 

 placed it under the Lindleyan name. 



The drawing, by T. Johnson, is, like the Plate, pro- 

 bably of the size of nature, but we have no means of 

 being certain of this.
