] BARBOUR — A NEW HORNED-TOAD 115 



It is important to point out that this new type shows no close 

 relationship with the rare form collected by Lyman Belding, 

 also on Cerros Island, and named by Stejneger P. cerroense. 

 (N. Amer. Fauna, 7, 1893, p. 187). 



I have adopted this rather informal method of description 

 for the reason that authentic examples of Phrynosoma blain- 

 villii Gray are to be found in every museum, while in com- 

 paring the stereotyped formal descriptions of horned-toads it 

 is very easy to miss the crucial characters in species at first 

 sight as similar yet really as fundamentally distinct as these.
