tify to its occurrence at Fort Huachuca. Dr. Fisher also collected it 

 at Fort Bowie (No. 22207). 



HOLBROOKIA MACULATA APPROXIMANS Baird. 



Collected at Fort Huachuca l)y Dr. Wilcox (Nos. 177ST; 19708- 

 19722; 21118-21119), Dr. Mearns (No. 21012), and Dr. Fisher (Nos. 

 22209-22211). 



UTA SYMMETRICA Baird. 



Exceedingly numerous. Lieutenant Benson sent in two specimens 

 (Nos. 11750-11751); Dr. Wilcox fifteen (Nos. 1778G; 19690-19703); Dr. 

 Fisher twenty-five (Nos. 22236-22260); and I, myself, obtained two as 

 late as the beginning of November (Nos. 15760-15761). They are 

 found from the Fort itself at least up to 6,700 feet altitude in the 

 mountains. 



SCELOPORUS SCALARIS Wiegmann. 



This species has been collected in the Huachuca Mountains only b}'- 

 Mr. Price. Mr. van Denburgh writes: 



Mr. Price's notes indicate that this is a rock-dwelling species, and that it occurs 

 at great altitudes. The specimens collected furnish, I believe, the most northern 

 record of its range. They are quite typical, and were collected near the summit of 

 the Huachuca Mountains, May 22, 1894, in Morses Canyon, April 7, 1894, and at an 

 altitude of 9,500 feet in the Huachuca INIountains, July 22, 1893.' 



SCELOPORUS CLARKII Baird and Girard. 



Apparently common, ])oth at the Fort and in the mountains. Dr. 

 Wilcox has sent six specimens (Nos. 17782; 19681-196S6; 21113-21111), 

 one of which was taken in a room in his house, while Dr. Fisher col- 

 lected ten (Nos. 22218-22227), some as high up as 6,000 feet altitude. 



The more specimens one sees of this species the more one wonders 

 that it was ever confounded with S. magister. The latter does not 

 occur in the Huachucas. 



SCELOPORUS JARROVII Cope. 



This lizard is one of the most common species in the Huachuca 

 Mountains, as testified by numerous specimens collected by Dr. Fisher 

 (Nos. 22228-22231), Dr." Wilcox (Nos. 19687-19689 and 21115-21117), 

 and myself (Nos. 15756-15759). It was also collected there by Mr. 

 Price. ^ 



I found Yarrow's lizard among- exposed rocks at various places 

 between 5,700 feet and 6,700 feet altitude during the first days of 

 November, 1889. The nights were very cool and the lizards did not 

 come out from the cracks and crevices in the rocks until toward noon, 

 when they could be found sunning themselves on the whitish rock^,
