BRANSON : SNAKES OF KANSAS. 



411 



Occurs throughout the southern and western part of Kansas. 

 While collecting fossils in Scott, Logan and Gove counties in 

 1903 the writer saw more than twenty Whip Snakes during the 

 month of July. They seemed to be more numerous than all 

 of the other species combined. In August only fourteen speci- 

 mens were seen, while more than twenty Rattlesnakes were 

 collected. The writer collected one specimen of flagellum in 

 Douglas county in May, 1903. This is the only specimen ever 

 reported from the northern or eastern part of state.
