 work, published in 1903, Simon makes certain changes in classi- 

 fication, which concern certain of our North American forms, 

 affecting Comstock 's tables, and attracting special attention to 

 one of the species found about Stanford University. 



The family Atypidae, formerly, was divided into three sub- 

 families, the Brachybothriinae, Hexurinae, and Atypinae, each 

 comprising two genera. All three sub-families are represented in 

 North America. All the rest of our Araneae theraphosae were 

 placed in the family Aviculariidae. By Simon's new arrange- 

 ment, the family Atypidae is limited to the two genera of the old 

 "Atypinae," the other two sub-families being transferred to the 

 Aviculariidae; the change, however, not at all affecting the
