A New Snake of the Genus Geophis From Chihuahua, Mexico

BY

JOHN M. LEGLER

In July, 1957, members of a field party from the University of Kansas Museum of Natural History, under the direction of Mr. Sydney Anderson, spent 12 days collecting vertebrates in the vicinity of Creel in southwestern Chihuahua. Among the specimens are two snakes representing an undescribed species of the genus _Geophis_. A description and illustrations of these two specimens were prepared and submitted for publication in the spring of 1958. At that time it came to my attention that Dr. Norman Hartweg, Museum of Zoology, University of Michigan, was also preparing a report on four specimens of the same species from two additional localities in southwestern Chihuahua. Upon learning of my work on the species, Dr. Hartweg generously loaned me his specimens and notes and allowed me to incorporate them in the present report. The snakes may be known and described as:

_Geophis aquilonaris_ new species

_Holotype._--Adult female, KU 44265, alcoholic; 23 mi. S and 1-1/2
