144 Slaty ironstone (Black-band). Lingula, Discina, Conularia, &c, together with 



Fish-remains, and Anthrapalwmon Grossarti. 



(The distance and thickness of the beds vary considerably in different localities.) 



Anthracosia acuta occurs in most of the beds below the Ell-coal ; Dijrfodus gibbosus, 

 Mcgalichthys Ilibberti, Iloloptychius minor, &c, arc found in nearly all the beds of the 

 Upper Coal-formation, but more abundantly below the Ell-coal. Spirorbis carbonarius 

 occurs in most of the beds up to the Splint-coal. 



In the " Upper Limestone series/' an ironstone, at 200 fathoms below the Ell-coal (a 

 few feet above the highest limestone), has yielded to Mr. Grossart a new Beyrichia {B. 

 fastigiata, sp. nov.). At 343 fathoms below the Ell-coal, in the " Lower Limestone series," 

 Dr. Rankine, of Carluke, gets Beyrichia multiloba (sp. nov.) ; and at about 350 fathoms, 

 Mr. Grossart has found some small Cypridina-like Entomostraca, similar to the Dajjhnoidia 

 Hibberti and D. primava. 



1 Dr. Rankine, of Carluke, has sent me specimens from about this horizon, in the Clydesdale Basin, 

 one of which has Cytheres and Spirorbis, and another Beyrichia arcuata and Anthracomya (?).
