14. Heterodon platyrhinus Latreille. Hog-nosed snake. — This 

 species was found throughout the sand region from Sand Point to 

 Rush Lake, and a specimen was collected at Port Austin b}^ Miss 

 Crystal Thompson of the University of Michigan Museum. The 

 sand country evidently furnishes favorable conditions for this snake, 

 for it could not be called uncommon, and specimens of large size 

 were obtained. One female (University of Michigan No. 37746) taken 

 on June 21 was 898 mm. in length and had a girth of 125 mm. 



Mr. Yax, a resident, informed us that specimens were occasionally 

 killed in the clay country near the sand region, but all of the in- 

 formation that we could gather from the residents was to the effect 

 that it was seldom found outside of the sand region. 



The color pattern of blotches is distinct in all of the specimens ob- 

 tained; indeed all but two are brightly colored, having a considerable 

 amount of bright yellow or orange in the ground color. (PI. XMI b.)
