A LIST OF OHIO SPIDERS.* 



By W. M. Barrows. 



The following list of 255 species of spiders is the result of 

 five years of intermittent study of the spiders of the state. 

 The work during the last two years has been carried on as a 

 project of the Ohio Biological Survey. 



I am much indebted to Mr. J. H. Emerton, of Boston, for his 

 kindness in identifying the specimens collected in 1913, 1914, 

 1915, 1916, and part of 1917, and for much other help and 

 advice. In the list, the specimens determined by Mr. Emerton 

 are marked by an (E) placed after the name. A few specimens 

 were determined by Mr. Nathan Banks. These are indicated by 

 a (B). I am also indebted to the following persons for small 

 collections made in various parts of the state: J. S. Houser, 

 Wooster, Ohio; P. R. Lowry, Wooster, Ohio; R. J. Sim, Jefferson, 

 Ohio; T. L. Guyton, Winterset, Guernsey Co., Ohio, and 

 Chester I. Bliss, Sandusky, Erie Co., Ohio. 



As far as possible the list follows the arrangement of the 

 Catalogue of Nearctic Spiders by Nathan Banks, U. S. National 

 Museum Bulletin 72, except that in each family the genera are 

 here arranged alphabetically. Included in the list are the 

 records of specimens collected in Ohio by Wm. Holden. These 

 are recorded as notes by Emerton in a Collection of the Arachno- 

 logical Writings of N. M. Hentz, Boston, 1875. These records 

 are marked (W. H.). Two records of Attidse are taken from the 

 Peckham's Revision of the Attidee of North America, and are 

 indicated by a (P). 



Several new species found in the collections will be described 

 in a later paper.
