NOTICE OF THE SKULL OF A DOG EXHUMED FROM THE 
ALLUVIAL GRAVEL OF NORWICH, IN 1851. BY MR. 
H. DENNY, A.L.S. 
From the difficulty which apparently exists in identifying 
the Fossil remains of particular species of animals, as for 
instance, those of the Genus Canis, I avail myself of this 
opportunity to bring before the Society a short notice of 
the skull of one of the Canidge, which I believe to be that 
of a Dog, recently presented to the Museum of the Leeds 
Philosophical Society, by P. O'Callaghan, Esq., of Cook-

employed in sinking a shaft for a new chimney at the gas 
works in the parish of St. Martins, at Palace, in the city of 
Norwich. 
The first comparative anatomist of the day, Professor 
Owen, in his valuable Manual of British Fossil Mammals, 
appears to be of opinion that it is extremely difficult to 
distinguish, with certainty, the skull of the Dog from that 
of the Wolf, from the specimens which have come under his 
observation ; and that the majority of those remains which 
have been assigned to the Dog, do not differ sufficiently from 
those of the Wolf to warrant their separation. There are, 
however, characters in the latter to which Professor Owen 
alludes, which I think are sufficient to identify the Wolf. 
These are the great size of the canine teeth, the greater 
length and height of the occipital sagittal crest, and the 
triangular space between the orbits being narrower and
