Chicotte Formation. The Chicotte facies was one favouring 
the development of reef corals and crinoids and the entrance of 
these faunas and the ecologic conditions to which the entrance 
was due, drove the mud loving animals of the Jupiter River to 
extinction or to other parts of the sea bottom. The thickness of 
the formation is 73 feet, the greater part of which consists of 
either a structureless mass of corals plastered over each other, or 
a breccia formed of the broken stems of crinoids. In some places 
the rock is so highly crystalline as to constitute a marble. 
The fauna consists of fifty-two species of which nineteen 
are introduced in the formation. This is the only one of the 
Anticosti formations in which the corals outnumber the brachio- 
pods in species and individuals ; in respect to species the ratio is
