A CLASSIFICATION OF THE NORTH AMERICAN SPIDERS

Abstract

The author has frequently been asked why he did not make a key for the families of spiders. He has answered that a correct key was impossible.But as such questions are getting more numerous, and connected with a desire to know something about spiders, the author has decided to put together what he could as a contribution to the classification of our spiders, principally for the use of those who are unable to obtain the costly works necessary for study.
