DESCRIPTIO^^ OF A NEW SAI.A^IANDER FROM IOWA. 



By Alexander G. Kuthven,

In May, 1911, the writer received from Prof. W. H. Norris, of 

 Grinnell College, a specimen of Amhystoma that could not be referred 

 to any of the described species. This salamander was labeled 

 ''Bloomfield, Iowa," and had been sent to Professor Norris by 

 Mr. George H. Berry, Cedar Rapids, Iowa. To verify the locality 

 record the writer wrote to Mr. Berry, who very kindly forwarded 

 three more of the six specimens obtained and the habitat data 

 included in this paper. A study of this material demonstrates that it 

 represents an undescribed species, and the writer takes great pleasure 

 in dedicating it to the eminent herpetologist, Leonhard Stejneger.
