21. Coluber taeniatus taeniatus (Hallowell) 



Two specimens from Boise, Ada County, August 29. 1916, 

 have scale counts as follows : 



22. Pituophis catenifer stejnegeri Van Denburgh? 



Two gopher-snakes (Nos. 45129, 45130) taken at Boise, 

 Ada County, June 25 and 29, 1918, have already been recorded. 

 (Proc. Cal. Acad. Sci., Ser. 4, Vol. X, 1920, p. 23). 



23. Rhinocheilus lecontei Baird & Girard 



So far as we know this snake has never been recorded as 

 occurring in Idaho. We have secured no specimens there. 

 The species is added to the list because of a specimen in the 

 Julius Hurter collection, now in the National Museum. This 

 specimen was sent to us, for examination, by Mr. Hurter, who 

 stated that it had been caught in Elmore County, Idaho, Octo- 

 ber 15, 1910. It is a female with scales in 25 rows; gastro- 

 steges 201 ; urosteges 43, the second to the twenty-fourth not 

 divided; anal single; supralabials 8-8, the seventh largest, the 

 fourth and fifth reaching eye ; infralabials 8-8, the fifth largest ; 

 preoculars 1-1 ; postoculars 2-2; loreal 1-1 ; temporals 1+3+4- 

 2+3+4; anterior and posterior genials nearly equal; red 

 blotches 29 on body and seven on tail. 



This species is as yet unknown from Nevada, Oregon, and 

 Utah. 



25. Thamnophis sirtalis concinnus (Hallowell) 



Our collections include ten specimens of this garter-snake. 

 These are one (No. 45428) taken at Boise, Ada County, July 

 17, 1918, and nine (Nos. 45770-45778) from McCall," Boise 

 County, August 6-11, 1918. They have the following scale-
