25. Cnemidopborus sexlineatus g-ularis i BAIRD d- GI- 

 RARD). A single individual [8722] was collected in the Magdalena 

 Mountains, Kelly, New Mexico. 



25. Cnemidophorus tigris BAIRD it (tIRARD. Several spec- 

 imens are in the collection from [2756 2757, 2762] Snake River plains 

 by Upper Salmon Falls; [2800] on Sage brush plains, near Blue l>akes, 

 Logan county, and [2826-282H] Blue Lake*. Canon, Logan county, 

 Idaho. t 



27. Cnemidophorns tigris nndnlatns (HALLOWELL). Mr. 

 Van Denburgh characterizes his C. stejnegeri from C (. undulatus as 

 follows : 



"Spots on throat few and small; central gular and collar scale<> 

 larger , C. t. unduldtus." 



"Spots on throat numerous and large, often forming irregular 

 transverse bands; gular and collar scales larger C. stejnegeri " 



Seven Cnemidophori from Carmel Valley, Monterey countj', Cal., 



are all distinctly of the C. stejnegeri type, except one [3397], which is 



' a j'oung specimen and in which the spots are fejp and small. This 



great extension of the lanire led me to examine the others in the 



collection. 



A jar of specimen, from Ontario, Cal., taken by Mr. R. E. Snod- 

 grass, contains four [3409, 3407, 3408, 3405] typical C. t. undulaliis, 

 one [34U] typical C. «te>e(;,eri;, while four [3406, 3410, 3412, 3414] are 

 intermediate, though they are nearer undulatus than the other form. 



Mr. Heller obtained typical stejnegeri at Warren's Wells and 

 Lytle Creek, San Bernandino Mountains, San Bernandino county, 

 and Cuyamaca Mountains, San Diego county, Cal., while he took 

 typical undulatus at Lytle Creek, J^an Bernandino county, and a small 

 intermediate specimen from ^iiverside, Cal. Mr. Coolidge took typi- 

 cal uudulalus at t [125] Grapeland, altitude about 2,000 feet, [134] 

 three miles west of San Bernardino, near Cajon Wash [or Pass], San 

 Bernardino count}', [13U] from same locality, with but a very few 

 spots, and a third one in Southern California, from whinh unfortu- 

 nately the t3g has been lost. 



The occurrence of the white-throated form in the South and the 

 spotted-throat form in the North indicate that C. stejnegeri is but a 

 synonym ot C (. undulatus. Although we have not as many speci- 

 mens to prove this as in the case of the identity of Sceloperus occident- 

 alis and Seeloporus biserialus, yet from what is at hand we feel certain 

 that future specimens will add to our proof and to confirm this be- 

 yond a doubt.
