ON A NEW CARBONIFEROUS LABYRINTHODONT FROM THE NEIGH- 
BOURHOOD OF BRADFORD. BY MR. LOUIS C. MIALL, 
CURATOR OF THE BRADFORD PHILOSOPHICAL SOCIETY. 
Remains of ampliibia are by no means rare in the coal- 
shales of the British Isles, and so many specimens of verte- 
brae, scales and teeth, belonging to this class, are found under 
various names in most of our museums, that it is a little 
strange that the genera archegosaurus, anthracosaurus, pholi- 
dogaster, and the rest, are so unfamiliar, and that writers on 
general geology go on repeating that no vertebrata higher 
than fishes are found in the coal-measures of Britain. The 
museum of the Bradford Philosophical Society contains 
many fragments of batrachians, which have been assigned to 
various fishes, some of them by eminent authorities. About 
a year ago, I placed a number of these aside for special 
examination, finding such peculiarities among them as bici- 
pital ribs, vertebrae with well ossified apophyses and labyrin- 
thodont teeth. The literature of this subject is so scanty 
and so recondite that I was unable to identify these remains 
with any described carboniferous amphibia, nor did the 
national museums throw any clear light upon the subject. 
At this time a few fragments, comprising several vertebrae 
and ribs identical with some already in my possession, were 
brought to me by an intelligent miner from Dudley Hill, 
who held out a hope of recovering further remains of the 
same animal. The remains were discovered in the roof of 
the Black Bed Coal at Toftshaw, near Bradford. After much 
delay and a good deal of labour (for the specimen was 
discovered in the roof of a coal-seam which had yet 
to be worked), a fine fossil, nearly six feet in length 
and in fair preservation, was recovered. Twenty-six 
vertebrae, eighteen ribs, a well-marked skidl showing 
forty-two teeth, and a very large number of scales, were
