whicli liaA'e grown out of these studies are receiving particular 

 attention and will form the subject of future discussion. 



Geology of Erie county and the region about Niagara falls. Prof, 

 I. P. Bishop of Buffalo has, at the request of the state paleon- 

 tologist traced the geologic formations on the Buffalo quad- 

 rangle of the topographic survey. Somewhat similar work has 

 been done in Niagara county for the Niagara gorge by Dr A. W. 

 Grabau, working with the cooperation of the Buffalo society 

 of natural sciences and this department. 



Correlation of the New York Paleozoic faunas with those of 



Canada. In consideration of the important light thrown on the 



value of the New York system of formations by the succession of 



the faunas in certain sections of the Dominion of Canada, the 



state paleontologist has spent some weeks in the careful study 



of sections exposed at Arisaig N. S., Dalhousie N. B. and Gasp^^ 



Quebec. Very considerable collections were there made, and the 



facts obtained will prove interesting in their bearing on the 



proposition referred to. 



Office work 



Catalogue of type specimens. This work was begun in the pre- 

 ceding year and has continued throughout the past year, as it

 catalogue has now been brought toward completion, lists having 

 been compiled for the following groups of organisms, the number 

 set opposite each name indicating types and illustrated 

 specimens.
