REPORT ON THE DEPARTMENT OF VERTEBRATE 

 PALAEONTOLOGY. 



By Charles R. Eastman. 



Several small collections of fossil vertebrate material have been 

 received during the year through either donation or exchange. 

 Among the accessions are additional specimens of ganoid fishes 

 from the base of the Waverly in Boyle county, Kentucky, unique 

 for their admirable display of the brain structure. Other additions 

 include an instructive series of casts and large-sized photographs 

 illustrating fossil fish material belonging to the American Museum 

 of Natural History in New York, a gift of Dr. Bashford Dean. 



A small lot of mammalian remains from the White River Oligo- 

 cene near Dickinson, N. D., was presented by Mr. Otis Tye, and 

 another lot from the same general locality, containing both mam- 

 mals and chelonians, was given by Mr. George F. Will. Through 

 Prof. R. S. Breed of Allegheny College a gift was received of 

 Waverly fishes from the vicinity of Meadville, Penn., including 

 Helodus comptus (type) and related forms. 



The type specimens of certain Lower Carboniferous fishes from 

 New Brunswick, mentioned in the last Report, have been under 

 investigation by Dr. Lawrence M. Lambe, of the Canadian Geo- 

 logical Survey, and were subsequently returned in good condition. 

 The same is true of a number of Leidy's and Marsh's types of 

 Triassic Ichthyosauria, which have been re-studied by Dr. John C. 

 Merriam in connection with his memoir on that group recently pub- 

 lished by the University of California.
