GRIFFITHIDES BARKEI. 
In the ‘Yorkshire Geological Society’s Proceedings,’ Dr.

Barke on the same horizon in Glamorganshire.

Remains of Bos primigenius near Doncaster.—Mr. Lloyd 
Roberts, the engineer for the South Yorkshire Joint Stock 
Railway, lately showed me a horn-core of Bos that had been 
found during excavations for the new line near Loversal. The 
core, of which the distal end is missing, measures 20 ins. along 
the outer side of the curve. Circumference at proximal end 
14.5 ins., and at the broken distal end 6.25 ins.—H. H.
