NORTH AMERICAN FAUNA. 



[No. 7. 



above with fifteen and sixteen scales to the head length, the number is 

 only twelve, while in two full-grown males from Fort Klamath, Oregon 

 (U. S. Nat. Mus. Nos. 15437-15438, Dr. Merrill, coll.), there are fifteen 

 and fourteen, respectively. 



[This species, which is a characteristic inhabitant of the Upper So- 

 noran and Transition zones in northern Nevada, eastern Oregon, and 

 Idaho, was A r ery abundant on the sage-covered plateau of Mount Ma- 

 gruder at an altitude of about 2,450 meters (8,000 feet) ; in the sage 

 plains on top of the White and Inyo mountains near the boundary be- 

 tween California and Nevada; and on the east slope of the Sierra Ne- 

 vada west of Owens Valley (at 2,450 meters, or 8,000 feet). It was com- 

 mon also among the sage and juniper on the Juniper Mountains along 

 the boundary between Nevada and Utah. 



Sceloporus graciosus is generally found in company with such Tran- 

 sition Zone species as the sage thrasher (Oroscoptes montanus), Brewer's 

 sparrow (Spizella breweri), the Nevada sage sparrow (AmpMspiza belli 

 nevadensis), the sage plains chipmunk (Tamias minimus pictus), the sage 

 brush pocket mouse (Perognathus olivaceus), and the sage plains sper- 

 mophile (Spermophilus mollis). — O. H. M.]

1891, with 



Sceloporus bi-seriatus Hallow. 



The great majority of Scelopori brought home by the expedition be- 

 long to this form, which in the region visited seems to occur every- 

 where above the desert belt at least up to 8,000 feet altitude. 



I can discover no difference between the examples from the moun- 

 tains inclosing the Valley of California and those from the isolated 

 desert ranges to the east, except that male specimens with the white 

 of the under surface replaced by black are more common from the lat- 

 ter localities. 



Among the localities from which specimens were brought are the 

 type localities of Hallowell's bi-seriatus, with its several color varieties, 

 of Baird's longipes, of Cope's smaragdinus, and of Boulenger's bocourtii;
