apply to the strata and fossils of the eastern part of Yorkshire, and 

 to illustrate by the aid of the arranged catalogues which follow, and 

 their accompanying plates." 



The detailed catalogues which follow contain a clear and syste- 

 matic arrangement of all the fossils hitherto discovered in the 

 several strata, with references to the plates of this or other works, 

 and to the localities in Yorkshire and various other parts of En- 

 gland. Each catalogue is terminated by a compendium of geolo- 

 gical inferences, and, where the subject allows, by a specific enu- 

 meration of the identifying or characteristic fossils*. As a spe- 

 cimen, we give the observations on the Kelloways rock: p. 142 and 

 143. 



" The Kelloways rock, seldom exposed in a satisfactory manner 

 in the South of England, and either deficient or concealed beneath 

 the Oxford clay from Wiltshire northward to the Humber, would 

 perhaps never have been recognised in Yorkshire, without attention 

 to its highly characteristic fossils. In the winters of 1820 and 1821, 

 Mr. Smith collected some specimens of Ammonites calloviensis, and 

 A. Kcenigi, from the north cliff of Scarborough ; which, the moment 

 I saw them, convinced me that he had discovered the Kelloways 

 rock in Yorkshire. Subsequent investigation, by proving that the 

 rock which had furnished these silent witnesses/ occupied, rela- 

 tively to other strata above and below it, exactly the place of the 

 Kelloways stone, removed all doubt from Mr. Smith's mind, and 

 enabled him to demonstrate that, amidst the acknowledged anoma- 

 lies of the lower oolitic series on this coast, the lines of geological 

 agreement may be securely drawn, to unite them with their type in 

 the midland and southern counties. His inferences on the subject, 

 like many other of his valuable observations, have now become the 

 common property of geologists, without the intervention of any 



Eublication by himself, which might remind those who profit by his 

 ibours of the praise that is due to the disinterested liberality of his 

 communications. 



" Of sixty species enumerated above, one-half the number occur 

 likewise in other strata on the coast of Yorkshire ; twenty-six of 

 these have been seen in the superior strata of the coralline oolite 

 formation ; twelve exist in inferior rocks which belong to the Bath 

 oolitic series, and at least eight are diffused alike through the strata 

 above and below it. These are dicotyledonous wood, Mya literata, 

 Mya calceiformis, Trigonia clavellata, Modiola, Pecten lens, Perna 

 quadrata, Turritella muricata. Ofthe thirty species which remain, 

 future researches may prove a considerable portion to be characte- 

 ristic of this remarkable rock ; but at present I shall content myself 

 with pointing out those which my own experience in Yorkshire has 



* " It deserves attention," Mr. Phillips remarks, " that the interesting 

 remains of Spongitz are nowhere so well developed as in England,]and per- 

 haps nowhere in England so well as in Yorkshire. On the shore near 

 Eridlington, they lie exposed in the cliffs and scars, and being seldom en- 

 closed in flint, allow their organization to be studied with the greatest ad- 

 vantage."
