Scarborough, where a fine section near the pier may be easily 

 and advantageously examined. It consists of the following : — 



ft. in. 



A. Moderately compact irony sandstone 1| feet thick, 



traversed by darkened veins of the same metallic

 Special to the bed .BeZ. ^orwa<j7t3 1 6 



B. Loose friable sandstones, without fossils 4 



C. Similar to A, but richer in organic remains, con- 



taining, besides those enumerated. Am. moch'olaris, 

 A. Goiuerianus, A. Chamusseti, Pholadoinya acuticosta, 

 Modiola pulchra, and Gryphcea dilatata. It is a more 

 nodular cherty bed than A 1 6 



D. Compact almost unfossiliferous sandstone, sometimes 



an Ammonite or a Belemnite in the large blocks ... 20

 to the Calcareous Grit above. AU the others (except Am. binatus, of which a

(6) 2 Two species named above are found in the Calcareous Grit; and to the 

 above list shoiild be added Am. perarmatus and Am. hexicostatus. The former
