Report of the Director. 13 



specimens of doubtful or questionable authenticity, will be rejected 

 and replaced by otliers from authentic localities. 



The Cretaceous and Tertiary collections from the Rocky moun- 

 tains, Wyoming and Nebraska, from Xew Jersey, Georgia, Alabama, 

 Texas and Mississippi, which had hitherto occnpied drawers, have 

 been arranged in some old table cases, temporarily placed for that 

 purpose upon the second floor of the museum. 



The collection of type specimens of Tertiary fossils from the valley 

 of the Amazon, purchased of Prof. James Orton, has been placed in 

 one of these cases, with the proper label attached. A list of the 

 specimens wdll be found appended. 



On the third floor, the collection of mounted fishes and of skulls, 

 has been properly labeled, and a classified catalogue of the former, 

 in accordance with the system of Prof. Gill, prepared by Mr. Lintner, 

 in which reference is made to the descriptions and figures of the 

 species in the Zoology of New York. A catalogue of the fishes will 

 be given in this report. 



In the Palseontological series, Mr. Whitfield has arranged and 

 labeled a collection of fossils from the Potsdam Sandstone of Kees- 

 ville, and a few from the falls of St. Croix. He has also placed in the 

 cases a labeled collection of Waldron fossils, of the Niagara group, 

 amounting to two hundred and seventy specimens, and has mounted 

 on new cards and properly labeled the greater part of the IS'ew York 

 Brachiopoda. A large portion of the series above the J^iagara 

 group was rearranged, in order to give space for the Brachiopoda of 

 the Oriskany Sandstone and those of the Hamilton group, and a num- 

 ber of fossils which had been allowed to remain in these collections 

 from the old arrangement, on critical examination, it was found 

 necessary to exclude. 



In the Chemung group, a collection of Brachiopoda of over three 

 hundred specimens from Rockford, Iowa, has been placed in the cases 

 and labels written for the species. The Ichthyic remains of this 

 group have also been arranged in small trays in the cases, preparatory 

 to their permanent disposition. 



The work of arranging and labeling the Carboniferous collections 

 in the geological series and the Cretaceous and Tertiary fossils on 

 the second floor, has been done by Mr. Whitfield. He has likewise 

 been engaged in the general work on the collections of the Hamilton 

 and Chemung groups, preparatory to their transfer to the cases, and 

 in labeling and packing several small collections for the academies.
