NEW YORK STATE MUSEUM 



by Becraft mountain near Hudson, celebrated in New York geol- 

 ogy for the completeness of its stratigraphic section and the 

 subject of a number of important papers, has been mapped in 

 detail, on a base scaled 1 mile to y 2 inch. This work with the 

 report thereon will soon be ready for publication. 



Correlation study of the k * Hudson river shale " formation has 

 been continued in Rensselaer county under specially favorable 

 conditions afforded by the Melrose water tunnel, which makes 

 an underground rock section about 1 mile in length. The Coral- 

 line, or Cobleskill, limestone has been carefully restudied from 

 its outcrops in Otsego county, eastward into Ulster county. 



In the office, time has been given to the completion of the 

 Catalogue of Type Specimens, which is now printed to about 

 600 pages, half its entire length, and, in connection therewith, 

 the ticketing and labeling of the type specimens have been carried 

 forward. 



Investigations have progressed on the relations of the Potsdam 

 sandstone and its fauna to the overlying formations, by Gilbert 

 van Ingen; on crustaceans of the Salina group, by C. J. Sarle; 

 on the pyrite fauna of the Tully limestone, by Dr F. B. Loomis; 

 on the paleontology of the Salamanca quadrangle, by Charles 

 Butts; and on the Guelph and Naples faunas, the graptolites of 

 the Beekmantown shales, the fauna of the Gaspe sandstone and 

 Grand Greve limestone and the fauna of the Elmira quadrangle, 

 by the paleontologist and his assistant. 



Full details of the work of this division are given in the 

 separate report of the state paleontologist. 



ZOOLOGY 



The assistant in zoology returned from field work Oct. 1, and 

 the first part of the year was spent in cataloguing and identifying 

 the material collected during the summer and in cataloguing the 

 material collected by Dr Bean. Part of the exhibition collection 

 needed attention and was gone over and a number of additions 

 were made to it. These amounted to 21 in the vertebrate series 

 and 51 in the invertebrate. Besides ihese, 67 descriptive labels 

 were prepared and placed with the specimens.
