In addition is to be mentioned a large series of showy quartzes and

INVERTEBRATE PALEONTOLOGY. 



The permanent accessions in this division amount to something like 

 68,000 specimens, though, naturally, this includes much duplicate 

 material. 



1. The largest single accession includes some 40,000 reserve speci- 

 mens transferred from the U. S. Geological Survey. These are for 

 the most part determined, labeled, and arranged in zoological and 

 stratigraphical order, and comprise the material which Dr. William 

 H. Dall and his assistants have spent years in gathering and working 

 up to its present high scientific value. 



2. The Survey has also turned over to this Museum another very 

 valuable, though in large part unworked, collection. This comprises 

 a series of some 1,932 Tertiary insects, brought together by Dr. Sam- 

 uel H. Scudder, besides many hundred original drawings, a great part 

 of which are unpublished. Mr. Charles Schuchert reports that this 

 transfer makes the Museum collection of fossil insects the largest in 

 America, if not in the world. 



3. Second only to the accessions mentioned above is the final por- 

 tion of the E. O. Ulrich collection. This embraces the mollusca and 

 miscellaneous materials of this most valuable collection, and comprises 

 no less than 15,000 reserve specimens and 500 lots of original types or 

 illustrated specimens. 



4. From the Imperial Academy of Sciences, St. Petersburg, Russia, 

 through Dr. Frederich von Schmidt, was received as a gift an excel- 

 lent suite of Lower Silurian Estland fossils. The material was selected 

 by Mr. Schuchert while in Russia for the purpose of making correla- 

 tions between the Russian and American faunas. 



5. From the Zoological Museum of the University of Copenhagen, 

 Denmark, through Prof. G. M. R. Levinson, there was received in 

 the way of exchange a fine series comprising more than 100 specimens 

 of identified European Mesozoic and Tertiary bryozoa. 



6. From the Yale University Museum, through Dr. C. E. Beecher, 

 was received as a gift a collection of 18 species, comprising 580 speci- 

 mens, of Hamilton brachiopods, representing the various stages of
