"These facts harmonise entirely with the opinion which I formed 
long ago, based upon the fact that at Crayford sliells of Cyrenaflumi- 
nalis are found in the same deposits of Brick Earth tliat have yielded 
remains of the Mammoth, the Woolly Rhinoceros, and the Musk Ox, 
and I have myself found them in the same inch-thick layer that 
yielded me dozens of bones and teeth of the Siberian Vole, Arvicola 
ratticeps." 
Mammalian Remains. — Ki one of the Field Excursions of the 
Hull Scientific Club in tliis neighbourhood two or three years ago, 
one of the members obtained two pieces of bone from the workmen, 
which at that time were thought to be the remains of the Mammoth. 
This find impelled me to pay regular visits to tliis and other gravel 
pits in the district, which, however, until recently, were without 
much result. 
During the past winter on calling here, the men had saved for 
me a vertebra of Cervus megaceros, a piece of horn of a ruminant 
which we cannot at present identify, and another piece of bone. I 
was also told that Mr. "Webb, of Burstwick, had several bones from 
these gravels, and on going to see that gentleman, he kindly handed 
them over to me, with the exception of the right radius and ulna of 
a horse (Equus caballus). As these latter specimens have a fresh 
appearance, with all the articular surfaces preserved, and they are 
neither water worn nor do they possess tlie peculiar red colour so 
characteristic of the bones found in these gravels, I am inclined to 
think that they have nothing whatever to do with the gravels, but 
belonged to an animal which lived at a comparatively recent date ; 
more especially as they were found near the surface. 
The other specimens are chiefly small, and in a very fragmentary 
condition. They consist mainly of parts of ribs and other equally 
undeterminable portions, some of which are so much waterworn as to 
resemble pebbles. 
At the beginning of this year on visiting the pit, I was fortunate 
enough to find the left radius and ulna of Bos taurus. This I took 
from the gravel close to the floor of the pit. Inside this specimeia
