an outlying mass of the Dicynodon rocks. He explained these phenom- 
ena by supposing that rocks of widely different ages had been metamor- 
phosed into masses having the same mineralogical characters. The dis- 
covery of certain fossils has lately verified the co ec aig respecting the 
Devonian age of the or and Bokkeveldt rocks ; . Rubid 
therefore infers that the rest of the old rocks are of she same age, Fi-

specimens belonging to the same genus found in the Dicynodon rocks, 
renders the probsbility of the truth of the second conjecture | very great.—

8. Anthraker erpeton, a new Carboniferous Reptile —Prof. Owen — 
described a fossil reptile from the Coal-beds of Llantrissent in Glam 
ganshire, Wales. It comes from the lower part of the “ Middle” if sh 
the upper part of the “ Lower” Coal-measures. The species is interme-

indicate that the animal belonged to “ that low air-breathing type which, 
with developmental condition of the bones like those in some fishes, and 
very common in Devonian, showed forms of the skeleton more like those 
fa ae fn reptiles, than in the modern air-breathing Batrachians.”—
