front of the glabella, similar to that of Avalonia, and also a 
similar furrow inside of the eyelobe. 
Correlation of Faunas based on these four species. 
A visual representation is often an important aid to the 
memory, and as preliminary to remarks under this head, I 
may here introduce a section of the Band 6. of Division 1, 
in which the Ellipsocephali and Protoleni have been found. 
The section is enlarged from one which appeared in the 
Transactions of the Royal Society of Canada, 1889, and is 
presented for the purpose of showing the position of the 
fossiliferous layers discovered by W. D. Matthew.

Fossiliferous horizons of Band } of the Acadian Division 
(Div. 1) chiefly as determined by W.D. Matthew. The 
section shows also the relation of Band 6 to the Paradoxides 
beds above (c—d) and to the barren sandstones or quartzites 
(a) at the base of the St. John group. It is enlarged from 
one at page 139, Vol. VII. (1V.) Trans. Roy. Soc. Can., 
where further relations of the St. John group are exhibited, 
and where, at page 142, the original description of this 
section is given.
