subordinate formations. On the second floor, similar labels have been 

 placed over the cases, designating the New York Minerals and the 

 classes to which they pertain, and over the mammalian fossil remains, 

 indicating their respective faunae and continental distribution. 



On the third floor the recent faunae are designated in like manner, 

 with sub-kingdom and class — the "]^ew York fauna " occupying a 

 separate part of the hall, and thus indicated, giving students a ready 

 means of reference to that part of the collection. 



These general labels will greatly facilitate the student in his study 

 of the collections, and, to the amateur or general visitor, they afl'ord 

 the means of locating and referring the objects in the different cases, 

 by the single, conspicuous label at the head. 



The lithological series of the ^N'ew York rocks from the Laurentian 

 to the Catskill Sandstone inclusive, occupying the table cases, has 

 been labeled by Mr. Lintner, under the supervision of the Director. 

 The label indicates the character of the rock, the contained fossils, 

 if any; the locality, and the formation to which it belongs. Those 

 specimens which formed a part of the original collections of the 

 Geological Survey, and are enumerated in the catalogue of the State 

 Cabinet published in 1853, are specially indicated by the label. 



There have been added to this series from the collections during 

 the past year, sixty specimens from the Huronian system, thirty 

 specimens from the Catskill Sandstone, and also specimens of the 

 ITew Red Sandstone from the E-ocky mountains. 



In order to complete a representation of the series between the 

 Catskill Sandstone and the Coal measures, collections have been 

 arranged in the cases, representing the most characteristic fossils and 

 specimens of»rock formations of the Waverly Sandstone, Burlington 

 Limestone, Keokuk Limestone, and Chester Limestone. Since the 

 Museum did not possess collections sufiicient for this purpose, the 

 deficiency has been supplied by selections from the private cabinet 

 of the Director, which have been temporarily deposited in the cases, 

 and indicated by a proper label. A list of these will be found under 

 the additions to the geological department "by deposit." 



In the lithological series, both in the table and wall cases, the entire 

 collection of Huronian rocks has been added during the year. The 

 investigations in the south-eastern part of the State has shown the 

 necessity of an entire revision of this series, so far as relates to the 

 Hamilton and Chemung groups. This has already been done for 

 the table. cases, and has been commenced for the wall cases, and all
