Notes on Some of the Species in the Preceding List. 
Acanthodes sulcatus, A g. — The type specimen from Wardie, in 
the Oxford Museum, is so poor a fragment that the reference to 
this species of the now pretty numerous and tolerably perfect 
examples of Acanthodes from the Calciferous Sandstone Series of 
the district is more a matter of guess-work than of absolute scien- 
tific proof, though at the same time there is no real reason for 
doubt. The fish attains to a very considerable size, and is very 
closely allied to A. Wardi, Eg., of the Coal Measures. The little 
“sulcus” or groove on the scales, figured by Agassiz, and upon 
which he founded the specific name, is very inconstant, and can 
hardly be used as a character; in fact, the only tangible mark 
which I can find to distinguish sulcatus from Wardi is a somewhat 
greater straightness and slenderness of the “ styliform ” bone. 
I am of opinion that the remains of Acanthodes which occur in
