ANTICOSTI ISLAND FAUNAS. 
IS 
lobites and such are present in considerable abundance. The 
fauna consists of one hundred and forty-seven species of which 
forty-six are brachiopods. Sixty-five species are introduced in the 
formation and one hundred and twelve species do not appear in 
the succeeding division. The apparently local extinction of this 
great number of species has no great significance since it was prob- 
ably determined by the entrance of the reef coral-crinoid faunas 
which were in complete possession of the parts of the Anticosti 
sea bottom whose preserved deposits now constitute the Chicotte 
formation. To what factors these faunas owe their entrance can- 
not be said and speculation appears idle. The species of the 
Jupiter River formation are: —
