ON THE FOSSIL FISHES OF THE MANCHESTER COAL-FIELD. 15 
On the Fossil Fishes of the Manchester Coal-field. J5?/ E. W. 
BiNNEY, Esq. 
The following remarks are extracted from an essay on this 
subject, published in the first volume of the Proceedings of the 
Manchester Geological Society, to which we have briefly adverted 
on former occasions_, but which are therein published in a more 
intelligible form, and therefore the better calculated to record 
the facts. It is not the intention to give a full description of 
the various genera and species, but merely to enumerate them. 
Megalichthys. 
The remains of this extraordinary genus of sauroid fish are 
not very common in the Pendleton coal-field, although found in 
abundance in the Ardwick limestones, and Bradford coal-mea- 
sures in the ascending — and the canal of Wigan, in the des- 
cending series of the carboniferous strata. Detached scales, and 
a large tooth, exceeding an inch in length, obtained by myself, 
and several teeth found by Mr. Ray, are the only specimens that 
have been met with in this locality. They all belong to the spe- 
cies M. Hibberti. 
Holoptychius. 
This fish occurs in great abundance at Pendleton, and several 
entire specimens have been discovered of individuals ten and 
twelve feet long. Its whole figure resembles that of a true fish 
more than that of the megalicthys. 
Palceoniscus. 
Specimens of this genus, named P. Egertoni by Prof. Agassiz 
are found in the Pendleton coal-field; but they are not common. 
The best hitherto met with, is one which shows all the bones of 
the head and the various shaped scales, having rough tesselated 
outer surfaces, some nearly rhomboids, and others acute angles. 
Diplopterus, 
Scales and jaws of a fish of this genus are sometimes found.
