Early Devonic of Gaspe. In my report of last year mention 

 was made of the comparative study of the Devonic faunas of New 

 York with their manifestation in the regions northeastward to the 

 Atlantic border. The treatment of this subject constitutes the 

 matter for Museum memoir 9, the first volume of which is now all 

 in type and the lithographic plates well forwarded. This volume 

 will concern itself with accounts of the Devonic faunas of Gaspe 

 and their relations to those of New York. The profusion and ex- 

 cellent preservation of the representatives of the New York faunas 

 in that region has afforded important light on the proper grasp of 

 the developments in New York. A conception of the fulness of the 

 presentation of these faunas is conveyed by the fact that it has re- 

 quired about 50 quarto plates to represent these faunas adequately. 



In 1900 I proposed definite stratigraphic terms for this Gaspe 

 Devonic, grouping the divisions which had previously been made 

 by Sir William Logan and to validate these terms it has been neces- 

 sary to analyze their faunas in detail. This work pertaining to the 

 eastern Devonic has proceeded with deliberation because of its 

 wide scope. It will require some time yet to bring it to a conclu- 

 sion and for this reason it has seemed well to establish some of the 

 results attained in the course of the work by a preliminary account 

 of some of the species, which has appeared in Museum bulletin 107. 



Paleozoic faunas of eastern Maine. In order to facilitate the 

 work referred to above, I commissioned Mr O. O. Nylander to make 

 collections of Devonic and Siluric fossils from the region of Cobs- 

 cook Bay, Me. His investigation, occupying a few weeks of the 

 field season, resulted in acquisitions of very considerable interest 

 both to the collections of the Museum and to the problems under 

 investigation. The localities represented are on Moose island, 

 Carlton island, and various points in the town of Perry. Fossils were 

 found for the first time in the purple shales at Pembroke and con- 

 siderable collections made from Siluric strata on the west side of 

 the Pennomaquan river and other points in the town of Pembroke. 



Early Devonic strata at Lake Memphremagog. An examina- 

 tion of the upturned and much cleaved and altered strata at the south 

 end of Lake Memphremagog has brought out some facts which may 

 serve to throw light on the character of the faunas. Near Knowl-
