I\ Mr. Clement Reid's "Geology of Holderness " (1885), a 

 special reference is made to the peat deposits at Hornsea and 

 to the animal and plant remains found therein. A list is given 

 of all the mammalian, fish, shell and plant remains then known 

 trom the lacustrine deposit at Hornsea as under : — 



Cham, sp. 

 Piniis sylvcsti-is ? 

 Potaiiiog-f/on, sp. 

 Alitiis g/ufinosa, cones and leav< 

 Oiienus robiir, leaves and cujis.

and Mr. Reid adds :— 



"Two curious points are broug-ht out by this list. F'irstly, 

 it shows that some of the extinct Pleistocene mammals, includ- 

 ing Felis spi'/cea and perhaps Elephcfi p?-iniiocniiis, are true 

 post-glacial species, not confined in the North of England, as 

 has been stated, to Inter-glacial Beds. Unfortunately, though 

 several teeth of the Mammoth have been found at Hornsea, 

 it is not quite certain whether any of them really belong to this 

 deposit, so it must still be left doubtful whether the species 

 really lived in Holderness in post-glacial times." 



"The second point is, that, notwithstanding caretui search, 

 the list of fresh-water mollusca is extremely small, forming in 

 this respect a marked contrast to the recent fauna at Hornsea 

 Mere. This is a real deficiency, and not due merely to imper- 

 fect search, I feel confident ; for, Ibr purposes of comparison, 

 the recent mollusca in the Mere were also collected, and in a 

 short time more than thrice the number of species were obtained.
