 OF IOWA, III 



By Ale^xander G. Ruthven 



The Museum of Zoology has been accumulating data upon 

 the reptile and amphibian faunas of lowa^ through expeditions, 

 loans and exchanges. The following notes are the result of 

 field work by the writer in Palo Alto, Clay and Dickinson 

 Counties, in the summer of 1918, and collections secured by 

 Dr. T. C. Stephens, Morningside College, Sioux City, Iowa, 

 and his students. The Museum is indebted to Dr. Stephens 

 for the loan of material and for permission to retain specimens 

 representing new locality records. 



The specimens noted in the list of species were taken by the 

 writer unless otherwise stated.
