17. — Sceloporus graciosus Baird & Girard. 



We have 94 specimens from Utah. There are four (Nos. 

 38300 to 38303) from Thompson. Grand County, May 30 to 

 June 4, 1913; 29 (Nos. 38497 to 38525) from the Wasatch 

 Mountains, Wasatch County, May 19 to June 20. 1913; 44 

 (Nos. 14159 to 14162, 27159 to 27195, and 30927 to 30929) 

 from Fort Douglas, near Salt Lake City, Salt Lake County; 

 eight (Nos. 38085 to 38092) from Beaver, Beaver County, 

 May 13, 1913; and nine (Nos. 38076 to 38084) from Milford, 

 Beaver County, May 16, 1913. 



Femoral pores in 90 specimens vary from 9 to 16; being 9 

 once, 11 twelve times, 12 fifty-three times, 13 sixty-nine times, 

 14 twenty-five times, 15 seventeen times, and 16 three times. 



18. — Sceloporus elongatus Stejneger. 



We refer to this species 65 specimens (Nos. 38235 to 38299) 

 collected at Thompson, Grand County, May 30 to June 4, 1913. 

 Femoral pores in 64 of these vary from 16 to 22 ; being 16 eight 

 times, 17 eighteen times, 18 thirty-four times, 19 thirty times, 

 20 twenty-four times, 21 ten times, and 22 four times. The 

 dorsal scales in a row from the interparietal plate to a line 

 joining the backs of the thighs in 45 of these lizards vary from 

 44 to 50; being 44 four times, 45 five times, 46 nine times, 47 

 ten times, 48 eight times, 49 once, and 50 eight times. 



Dr. Stejneger, at our request, has very kindly compared 

 three of these specimens with the original specimens of 6^. 

 elongatus,. 2in(l writes that he finds them identical. It is inter- 

 esting to find in Utah this species which has been known only 

 from the original Arizonan specimens. This species differs 

 from 5". biseriotus in general coloration, in having two blue 

 spots on the throat (as in 5. occidcntalis and ^. consohriniis) 

 and in its smaller dorsal scales. We are not certain that Utah 

 records of 5". consohriniis may not be based, at least in part, on 

 this species, although the coloration is quite dift'erent. 5". 

 smaragdinus was originally described from specimens from 

 Utah and Nevada, but its 14 femoral pores, 41 scales from head 

 to base of tail, and entire middle portion of throat blackish 

 blue, indicate that it was based upon specimens of 5. biscriatiis.
