REPORT OF THE STATE PALEONTOLOGIST 1900 11 



Chemung section in Chautauqua county. In connection with in- 

 vestigations of the Chemung beds in Cattaraugus and Allegany 

 counties and in cooperation with the department of paleontology 

 of Cornell university, Dr H. F. Cleland is studying the develop- 

 ment of the same series in Chautauqua county. To Dr Cleland's 

 work, carried on under the immediate supervision of Prof. G. D. 

 Harris, the paleontologist has found it practicable to afford some 

 aid. 



Fauna of Rondout waterlimes in central 'New York. By the co- 

 operation of Lewis J. Bennett^ president of the Buffalo cement co. 

 the museum has been enabled in the past two years to increase 

 somewhat its representation of the remarkable and interesting 

 Eurypterid crustaceans of that formation in Erie county, where 

 they occur in the greatest abundance and variety of expression. 

 Mt Bennett has kindly promised that the state museum shall 

 «hare with the cabinet of the Buffalo society of natural sciences 

 the output of his quarry in these fossils. It is essential to the 

 Integrity and completeness of our museum that it shall possess 

 an extensive representation of these fossils; for nowhere else in 

 America are they present in such quantity and diversity as in 

 this state. The most generous assurance of Mr Bennett has made 

 it seem to me very desirable that the museum shall exploit more 

 fully this peculiar crustacean fauna throughout the extent of the 

 outcrops of this formation. For some years past study has been 

 made of the character of the waterlime beds east and west in 

 the state, and during these investigations a consiiderable number 

 of these crustaceans have appeared, though rarely of good quality. 

 For some reason not yet fully understood, these organisms are 

 found with some frequency in three regions in the state: Erie 

 county; the vicinity of Union Springs, Cayuga co., from which 

 a considerable amount of material was collected last year by the 

 paleontologist and Mr Luther ; and southern Herkimer and Oneida 

 counties, particularly the towns of Litchfield and Paris. From 

 the last named region some interesting specimens have been taken 

 in the past, and of them the museum has had a small representa- 

 tiou. The localities in the town of Litchfield were visited bv the
