(This is the horizon to which the Estherian 

 shale found at Lowndsley Green, Chester- 

 field, belongs ; see p. 28.) 



The lower part, forming the roof of the coal, 

 sometimes contains Aviculo-pecten, Gonia- 

 tites, &c. Estheria ? (See below.) 



Aviculo-pecten, Goniatites, &c, in the roof. 



Aviculo-pecten, Goniatites, &c, sometimes occur 

 in the roof; and often, shells resembling 

 Lingula, Modiola, &c. 



Aviculo-pecten, Goniatites, &c, in the "roof" 

 sometimes ; but generally shells of Union- 

 idce (?), with fish-remains : also Cypridee, 

 with Microconchus carbonarius, in some of 

 the roof-shale ; also Estherice. 1 



Aviculo-pecten and Goniatites. 

 Aviculo-pecten and Goniatites, sometimes. 



1 Mr. Binney thinks that the Estherian shale of Shaly Brow is from this roof; but some other geologists 

 think that it is from the roof of the Forty-yards Coal above.
