DR. J. W. DAWS OR ON ERECT TREES CONTAINING ANIMAL 
If we inquire as to the footprints of larger size included in the genus Sauropus . we 
know by the evidence of osseous remains that some large Batrachians inhabited the 
areas of coal deposition in Nova Scotia. More especially Baphetes glaniceps (Owen) 
must have been an animal of sufficient dimensions to have produced footprints like 
those of Sauropus unguifer. A second species of Baphetes is probably indicated by a 
jaw-bone found at the South Joggins, and which I have named provisionally B. minor. 
The Eosaurus Acaclianus of Marsh must have been a large animal; but we do not 
yet know if it was capable of walking on the land. 
On the whole, the evidence of footprints serves to indicate that both Lcibyrintho- 
dontia and Microsauria existed in Nova Scotia throughout the Carboniferous Period, 
and that very many of the larger and important species still remain to be discovered. 
It seems remarkable that, while remains of Fishes are so abundant in the carboniferous 
shales of Nova Scotia and New Brunswick, nothing is as yet known as to the more 
aquatic types of Batrachians found so abundantly in the carboniferous strata elsewhere. 
This may either indicate a local paucity of these creatures, or may be a mere accident 
of preservation or discovery.
