Abstract. — The 621 species of spiders known to occnr in Utah as recorded in the Hterature or Utah universities' collections are listed with their junior synonyms and collection localities. Two-fifths (265 species) are known from onlv one locality each, and only one-fifth (123 species) from five or more localities in the state.
