A List of California Arachnida 



This list is compiled from already published hut scattered papers. Many of these 

 are local records of specimens and new species collected hy many students through a 

 number of years and determined for us for the most part by Banks and Chamberlin. 

 As numerous earlier papers in this Journal have taken up the distribution of local 

 forms only a hint of this will be given. There are included in this list records other 

 than local. If the distribution is general some indication is given. A few hints as to 

 characteristic features are given when possible. The family characteristics are com- 

 piled by the aid of the works of Banks, Ewing, Comstock and several others. In 

 order to save space the literature references are given in abbreviated form at the end 

 of each section, especially as there are a number of papers and lists already published 

 which give this material in great detail.
