REPORT OF THE STATE PALEONTOLOGIST I9O3 7 



was not brought out in the early surveys of the region, and we owe 

 our present knowledge of them, specially of the former, chiefly 

 to the labors of Professors Brainerd and Seely of Middlebury 

 Vt., whose investigations however were chiefly confined to Ver- 

 mont, and to Professor Whitfield, who has described most of 

 the fauna as now known. The congeries of life forms herein 

 is surprisingly profuse and embodies a multitude of novel 

 species of notable interest. It was deemed necessary for a suc- 

 cessful exploitation of these two formations to determine the 

 detailed succession of the faunas bed by bed at the typical ex- 

 posures, Beekmantown and Chazy. Thereafter the exposures on 

 Valcour island, which are of unusual interest, were examined 

 in detail, specially the cliffs along the west and south shores. 

 A large amount of material was acquired by this work, and some 

 account of the new forms obtained is appended to this report. 

 A fuller revision and description of the entire faunas of the Beek- 

 mantown and Chazy formations will be undertaken when the 

 other exposures in this region have been carefully examined. 



Correlation of the New York Devonic with that of Gaspe, Canada. 

 In a previous report record was made of the effort to elucidate 

 the composition and origin of the early Devonic faunas of New 

 York by a comparative study of the Devonic areas in the eastern 

 counties of the Province of Quebec. Here the faunas attained 

 unexampled profusion of development and it was shown as a 

 lesult of a brief collecting trip to Grande Greve, Quebec and Dal- 

 housie N. B,, by the paleontologist in 1900, that a close examina- 

 tion of the fauna of the Grande Greve limestones would bring 

 out many facts helpful to the problems before us in New York. 

 The Grande Greve limestones exposed on the north shore of 

 Gaspe bay are repeated only at Perce, on the westernmost coast 

 of Gaspe county, south of Gaspe bay, and this spot was visited 

 during the past summer. The environs of the fishing village of 

 Perce are of extraordinary interest to the student of the older 

 rocks. The limestone series has been greatly disturbed here, the 

 faulting having brought up sections of those rocks in different 

 places and at differing angles. Only the Perce rock, a stupen-
