THE SPIDERS OF ONONDAGA COUNTY. 
Horace W. BriTCHER. 
There have been very few local lists of spider faunas pub- 
lished in the United States. Dr. George Marx has collected 370 
species in the District of Columbia and listed 308 of them, the 
remaining 62 being undescribed. Dr. Nathan Banks has listed 
278 species from the neighborhood of Sea Cliff, Queens county, 
N. Y., and 363 species from the region about Ithaca. Mr. J. H. 
Emerton has briefly described 343 species from the New England 
States. The present list is composed of 159 identified species and 
8 species, probably new, identified only as to genus. It does not 
contain the smaller spiders of the family Therididae, of which a 
large number have been collected and only a few identified. Many 
Drassidae and Clubionidae and some Lycosidae, Thomisidae and 
Attidae remain unindentified. Of the spiders collected those 
belonging to the family Epeiridae have probably been more com- 
pletely identified than those belonging to any of the other larger 
families. Of this group the county has 37 species as against 43 
for Ithaca and 53 for New England. It seems reasonable to 
believe that a fairly complete list of the spiders of the county 
would enumerate considerably over 300 species. 
The collecting has been done chiefly in the towns of Onon- 
daga, Salina, DeWitt (about Jamesville), Pompey and Tully. 
The eastern, northern and western towns have been almost en- 
tirely unvisited. 
For the sake of uniformity the nomenclature used is that of 
Dr. Marx’s Catalogue of Described Aranae of Temperate ‘North 
America published in 1890 by the Smithsonian Institution. The 
descriptions by Dr. Banks, the arachnologist of the National Mu- 
seum;, Mr. Emerton’s description of New England Thomisidae 
and Attidae and Dr. J. H. McCook’s descriptions of Epeiridae 
have been published since that date. At present the nomenclature 
of the entire group is in a very unsettled state and it is to be hoped 
that the near future may yield a revised list of North American 
spiders with synonomy to date and with keys to the genera of the 
different families.
