I therefore propose to name the Asterophyllites tuherculata, 

 L. and H. {not Sternb.), Stachannularia (?) Northum- 

 BRIANA, Kidston, 



PL XV. Calamites nodosus, L. and H. 



Locality.- — Felling Colliery, near Newcastle-upon-Tyne. 



Horizon. — Lower Coal-Measures. Eoof of Low Main Coal. 



Remarks. — The main stem in this figure is the Calamites 

 EAMOSUS, Artis. The supposed foliage branch has no con- 

 nection with the stem, and is a branch with cones, referable 

 to the genus Paloeostachya. The fruit of Calamites ramosus 

 which is known, is generically distinct {Calamostachys) from 

 the Palceostachya occurring on this slab.^ The type is in the 

 " Hutton Collection." 



PL xvi. Calamites nodosus, L. and H. 



Locality. — Felling Colliery, near Newcastle-upon-Tyne. 

 Horizon. — Lower Coal- Measures. Eoof of Low Main Coal, 

 Remarks. — The type of this figure is also preserved in the 

 collection. The plate only shows one, of the remains of at 

 least six stems, that occur on the slab. Not having the 

 necessary works of reference beside me when examining the 

 fossil, I could not determine it further than merely to refer 



it to the genus PALiEOSTACHYA. 



PL xviL ASTEROPHYLLITES GRANDis, L. and H. {not Sternb.). 



Locality. — Felling Colliery, near Newcastle. 

 , Horizon. — Lower Coal-Measures. Eoof of Low Main Coal. 



Remarks. — The type, which is in the " Hutton Collection," 

 may probably be referred to Weiss' genus Calamitina {Cyclo- 

 cladia, L. and H.), but the specimen is not very distinctly 

 preserved, and the foliage is too faintly indicated to allow of 

 its true form being discovered. 



PL XviiL ASTEROPHYLLITES LONGIFOLIA. 



Locality. — Jarrow Coal-Mine. 



Horizon. — Lower Coal-Measures. 



Remarks. — The original specimen appears to be lost. The
