general reader by giving not only a catalogue of the books and 

 maps, but also a general idea of their contents. As the palae- 

 ontologist has to deal with the species described under each 

 genus I have included a full list of fossils, which will save the 

 student many a weary hour of laborious research through 

 many volumes. 



The catalogue has been arranged under different heads, 

 giving the student a direct reference to the contents of dif- 

 ferent publications. Following is the arrangement: 



Part I. Publications of the State of California. 



Part II. Publications of the United States Government. 



Part III. Publications of Scientific Societies. 



Part IV. Publications of State Geological Surveys other 

 than that of California. 



Part V. Miscellaneous Publications. Manj' of them are 

 references to early reports on gold and other minerals, in- 

 cluding trips to the gold fields of California. All of these 

 books contain references to mines and local geology. 



Part VI. A list of the published maps of California. This 

 will be found useful to all citizens of the State.
