arenaceous and eon<i;lomeratic rocks, which extend westward from 

 Pentewau tlirough Granipound, by me in 1890, from the descriptions 

 of the type in De hx Beclie's Keport, pp. 83 and 92, near Pentewan 

 and Grainpound ". Messrs. C. Davies Sherborn and XJptield Green' 

 consider the Granipound Grit to he equivalent to the ' I'ortscatlio ' of 

 Mr. J. \^. HilP and correlate it with the Upper Gedinnian of the 

 Continent. The Portscutho series is placed by Mr. Hill" in the 

 Lower Palaeozoics. Mr. J. H. Collins^ was disposed in his earlier 

 work to place the Ladock lieds in the Upy)er Silurian, hut later* he 

 appears inclined to assign them to the Lower Devonian. The corre- 

 lation proposed by Mr. Green is questioned by Mr. Ussher,* who, 

 however, agrees tliat the Grainpound Grits are of Lower Devonian 

 age and includes tliem in the Meadfoot Group.'' They are also placed 

 in the ' Lower Devonian ' by Mr. Clement Reid,^ but higher in 

 position than according to Mr. Ussher's view. 



It would be unsafe to attach too much weight to the evidence of 

 the imperfect specimens above described, though their characters 

 certainly suggest that the Grampound Grit was deposited during 

 Upper Gedinnian or possibly ' Siegener Schichten ' time.

FOR many years palteontologists have eagerly awaited a description 

 of the large collection of fossil fishes from the Wealden formation 

 of Bernissart, I5elgium, found associated with tlie remarkable skeletons 

 of Ifjuanodon and other reptiles of whicli a preliminary account was 

 published more than twenty years ago by Professor L. DoUo. The 

 long delay, however, has not been altogether in vain \_ for the Brussels
