revision of cayuga lake spiders, 

 by nathan banks. 



In The Proceedings of the Academy of Natural Sciences 

 of Philadelphia for 1892, pp. 11-81, 1 gave a list of spiders collected 

 in the vicinity of Ithaca, N. Y. It was the first important local 

 list published in this country. Twenty-five years have passed since 

 its preparation, and twenty-five years in any department of natural 

 history produces many changes. A number of the new species 

 have proved to be synonyms, a number have been redescribed by 

 others since, and many species have had either their generic or 

 specific name, or even both, changed since then. 



It is the purpose of this paper to briefly review these changes and 

 to give a few notes and figures of such forms as seem to have escaped 

 collection in recent years. 



The arrangement is the same as in the original work. Species not 

 mentioned are unchanged.
