the ultimate analysis of such a fauna a clue to the direction of its move- 

 ment. Comparisons with the Hamilton fauna of New York taken as a 

 whole fail to reveal such, but comparisons instituted between this particular 

 representation of the Hamilton fauna and the later than Middle Devonic 

 fauna of western Europe do indicate without qualification that the Gasp^ 

 sandstone species find their equivalents therein. Just as Tropidoleptus 

 and Vitulina ]iav(; [Kjinted out the earlier migratory course of the fauna so 

 these show its later and directory phases. There is therefore a harmony in 

 tli(j inception period of laj^oon conditions along the Atlantic border and 

 Appalachian gulf, for in New York these were initiated with the close 

 of the Hamilton and in Gaspe not long, if at all, before the opening 

 of this time. They do not, either here or elsewhere in eastern America, 

 date back earlier. 



Distribution of the Gaspd Devonic limestone and sandstone series tozuard

 Logan, Bell, Ells, Low, Barlow and other members of the Canadian 

 Survey have indicated the outcrops and boundaries of these formations 

 inland in western Gasp6 and in Rimouski counties. The summation of our 

 present knowledge of their probable extent through central and northern 

 Gasp6 is depicted on Ells's geological maps of 1882-84. Few fossil lists 

 have be('n Lfiven in conncxtion with these western determinations Init the
