mere lithological resemblances to rocks in distant countries 
have been used as a basis for correlation. The futility of these 
attempts is indicated by the confusion of names and of opinions 
that has arisen. Judging from the relations of this system to 
associated terranes as well as from the most recent investigations 
of its fossils, it seems evident that as a whole it may reasonably 
be correlated in a general way, with the Jurassic and Triassic 
systems of Europe. To attempt a more minute correlation at 
the present time does not seem warranted. 
The desirability of a commonly acceptable name for this sys¬ 
tem is sufficiently obvious, if for no other reason than conven¬ 
ience in discussing its relation to other terranes. The question 
is, what name shall be used? The diversity of opinion regard¬ 
ing its relation to European rocks renders it evident that a name
