OCCURRENCE OF A TOOTH OF THE BLUE SHARK (CARCHARIAS 
GLAUCUS) IN THE BRICK-EARTH OF CRAYFORD, KENT. 
Str,—I have lately received from a member of the Geologists’ 
Association, Mr. Henry E. Jones, of Haling, an interesting Selachian 
tooth from the Thames Brick-earth at Crayford, Kent. The specimen 
was discovered by Mr. Jones himself in the well-known pit from 
which the numerous Mammalian remains are obtained; and its 
mineral condition is such as to leave no doubt that it is a true 
Pleistocene fossil. The tooth may be assigned without much hesita- 
tion to the symphysial region of the lower jaw of an adult Blue 
Shark (Carcharias glaucus), about 8ft. in length; and the fact that 
it is merely a hollow germ, and yet unbroken, shows that it cannot 
have been subjected to much rough usage before entombment. 
Many of the Selachian remains of Pliocene deposits are practically 
indistinguishable from the corresponding parts of living species still 
inhabiting the Northern Hemisphere; and it is natural to expect 
that similar forms will be found in beds of Pleistocene age. At 
present, however, we are only acquainted with evidence of Galeus 
canis, Acanihias vulgaris, Raja batis, and Raja clavata, described by 
Mr. E. T. Newton from the Forest. Bed Series of Norfolk; and the 
new Crayford discovery is still more interesting on account of the 
distance of the locality from the existing coast-line.
