1866.] WHITAKEE — LOWER LONDON TERTIAEIES. 421 



(8). Mr. C. Evans's note in the ' Geologist/ vol. vii. p. 34 (1864) ; 

 and a few other short notices of fossils. 



It is not, however, wholly made from the above published works, 

 but has been largely added to from unpublished lists, in my Note- 

 books, of the collections of Mr. G. Dowker, F.G.S., Mr. J. Eeid and 

 the Eev. Dr. Mitchinson (Canterbury), Mr. J. Horsley (given to the 

 British Museum), Mr. J. G. Goodchild (Sittingbourne), given to the 

 Geol. Survey, and Mr. J. Marten (Ensinge), also in part given to 

 the Survey, besides many notices of fossils found whilst working at 

 the Tertiary beds of Kent. Of course I cannot hold myself responsi- 

 ble for the right identification of the species in the published lists ; 

 each observer must answer for his own determinations. Some of 

 these, no doubt, are wrong ; but that is not my fault, and I shall be 

 glad to have corrections and additions. 



Sometimes I have been unable to state in what particular bed a 

 fossil has been found. This, again, is not my fault, but is owing to 

 the fact that authors are somewhat careless in giving information as 

 to the exact position or locality of the fossils they find : thus many 

 specimens are recorded simply as from " Woolwich Beds," whilst of 

 others one can learn no more than that they are " Lower Eocene." 

 I am sorry to say that the last case often occurs, just where it is 

 most to be regretted, in the elaborate monographs of the Palseonto- 

 graphical Society " On Eocene Shells," which,, whilst being almost 

 perfect from a zoological point of view, sometimes are of little use to 

 the field-geologist. 



The classification of the large groups follows that of Prof. Huxley 

 in the ^ Catalogue of Fossils in the Museum of Practical Geology/ 

 1865, p. Ixxv.
