Besides our own collection, we have had an opportunity, while 
drawing up the following Catalogue, of examining the fine collec- 
tion of fishes from the Marl-slate in the Museum of the Natural 
History Society of Newcastle, and the collections of fossils from 
the Magnesian-limestone in the possession of Mr. W. K. Loftus 
of Newcastle, Mr. G. Tate of Alnwick, and Mr. T. E. Backhouse 
of Sunderland.
