10 NEW YORK STATE MUSEUM 



The heads of the various departments are in charge of the 

 collections. 



Paleontology. Collections made by the California geological 

 guryey-: type or representative specimens of all known California 

 fossils; splendidly preserved fossils illustrating the paleontology 

 of the state; a large series illustrating the development of in- 

 vertebrate life in North America and a carefully selected series 

 of crinoids from Crawfordsville Ind. 



Mineralogy. A very large systematic collection and a series of 

 glass and wooden crystal models. 



Economic geology. Sets of specimens from mines on the Pacific 

 coast: gold, silver, mercury, iron, copper and coal, showing for 

 each mine the ores, veinstones, wall rock, and other important 

 features. 



Structural geology. Fine models of the more interesting geolo- 

 gic regions, chiefly in the United States containing an excellent 

 relief map of the peninsula of San Francisco from 37° 30' to the 

 Golden Gate, on a scale of 2 inches to the mile. 



Lithology. Many hundred rock specimens from the eastern 

 states and territories, England and the European continent, and 

 a large number of California rocks collected by the state geo- 

 logical survey; also 3600 slides for microscopic study. 



Zoology. Good collections of both invertebrates and verte- 

 brates. The collections of marine invertebrates from the Pacific 

 coast, specially of the groups Coelenterata, Crustacea, Echi- 

 nodermata, Annelida, Bryozoa, and Tunicata, are rich and are 

 being rapidly increased. There is a large type collection of Cali- 

 fornia molluscan shells, and besides a general collection in the 

 same group of 2300 specimens. In entomology the agricultural 

 department possesses a collection of over 2000 determined 

 species of beetles. There is also a large collection of Lepidop- 

 tera. The collections of amphibians, reptiles, birds and mam- 

 mals are fairly representative of the California fauna in these 

 groups. The collection of Alaska birds and mammals is good. 

 The collection of vertebrate skeletons has been greatly enriched 

 recently through a gift of about 50 new types. These were
