Distribution. — The Northern Alligator Lizard is a 

 species of western Washington and Oregon, whose range 

 seems to extend south on the western slope of the Sierra 

 Nevada of California at least as far as Red Point, Placer 

 County.* It may, perhaps, live also in the northwest- 

 ern corner of the State. I believe that this form will 

 be found to intergrade with both G. burnettii, of the 

 coast, and G. palmeri, of the southern Sierra Nevada. 

 Northward its range extends to Vancouver Island. It 

 is very abundant near Puget Sound.

 example of G. palmeri.
