7. Ofe7J Vol. 42, pp. 131-142 March 30, 1929 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHI NOTES ON THE SPIDERS OF WASHINGTO COUNTY, UTAH. BY R. V. CHAMBERLIN AND A. M. WOODBURY. The spiders listed in the present paper were taken mostly at two localities in Washington County, which occupies the extreme southwestern corner of Utah; namely, St. George and Zion National Park. While some specimens were col-lected by the senior author in 1923 and in 1927 by far the greater number were secured by Mr. Woodbury, who, during the summer season, has served as naturalist for Zion National Park for several years past. We plan through further collect-ing to bring the list for the Park in particular to essential com-pleteness. Types of the new species described are in the collection of the senior author. THERAPHOSIDAE. Eurypelma steindachneri (Ausserer). St. George. Females and immature specimens are referred tentatively to this species. DICTYNIDAE. Dictyna dactylata Chamberlin. St. George. Six females taken in 1925, 1926 and 1927. A form re-sembling volucripes but much smaller and with a different epigynum in which the septum typically ends caudally in a slender chitinous finger, though this may connect with the caudal rim which does not extend far laterad on each side as it does in volucripes. Dictyna volucripes Keyserling. St. George. One female referred to this species was taken several years ago by V. M. Tanner. 10— Proc. Biol. Soc. Wash., Vol. 42, 1929. (131)
