1823.] Ashmolean Catalogue of Extraneous Fossils. 379" 



are interpolated, and marked a, b, c, &c. in addition to the 

 number. 



The local index which I have made shows, that 30 places, 

 which I shall mention presently, furnished more than one-half 

 of the whole collection, or 1065 of the specimens enumerated ; 

 consisting of 477 fossil shells, and 588 other bodies, mostly 

 organized ; the produce, apparently, of twelve of the assemblages 

 of strata, ascertained by Mr. William Smith, and enumerated in 

 his Geological Table, from the London clay downwards to the lias. 



It hence appears, that 25 of the places, among the most pro- 

 ductive of Ashmolean specimens, furnished none to the Smithean 

 collection, of about 1155 specimens of shells, &c. which Mr. S. 

 in June, 1816, deposited in the British Museum,* whose loca- 

 lities, he has partly mentioned in two quarto works, " Strata 

 Identified," and a " Strati graphical System " (but which works, 

 unfortunately, remain unfinished) ; and which localities, as far as 

 they have been published, are enumerated in alphabetical order, 

 in the il Philosophical Magazine," vol.50, p. 271. 



For the purpose of ascertaining the strata of the following 

 places, I have consulted Mr. Smith's separate " Geological 

 County Maps," except as to Lincoln and Northampton counties, 

 which are not yet published, and as to which, I have consulted 

 his original " Geological Map of England," published in Septem- 

 ber, 1815 ; which last was accompanied by an interesting 

 " Memoir," which has, I think, been strangely overlooked, by 

 almost every subsequent writer.

 near Minster, in Kent, 5 shells and, in all, 25 specimens, are

 any one place ; Garford (or Garvord) 4 miles W by S of Abing- 

 don, Berks, 9 shells and 26 others; Marcham, 2l miles W by
