32 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 



Distribution. — Northwestern Utah, also Idaho. 



Remarks. — The seven specimens at hand from Utah all have 

 41 rows of scales. The same number of rows is found in two 

 specimens from Blue Lake and Hood's Valley, Kootenai 

 County, Idaho, which may be regarded as belonging to this 

 subspecies. The only other specimens with 41 rows of scales 

 of which I have record are one from Red Point, Placer County, 

 California, and one from Fyffe, El Dorado County, California. 

 These are to be regarded as instances of individual, or possibly 

 geographical, variation in Charina hotter bottcu, for other speci- 

 mens from the same localities have 43 rows. It is these two 

 Califomian specimens which cause me to regard the two forms 

 as subspecies rather than species. All other specimens from 

 California, Nevada, Oregon, and Washington, of which I have 

 records, have more than 41 rows of scales. Thus, of forty- 

 seven specimens from these states, fifteen have 43 rows, twenty 

 have 45, six have 47, and six have 49 rows. A specimen in the 

 Paris Museum is said to have 43 to 45 rows and to be labeled 

 "Utah Terr". In the light of the present evidence it seems 

 probable that this locality is erroneous.
