14. Sceloporus boulengeri Stejn. 



A very large number of Seelopori collected at Mazatlan and 

 Tepic, are certainly identical with Dr. Stejneger's S. boulengeri. I 

 believe that this is the same form as Cope's S. oligoporus. It may 

 even be true that these are not distinguishable from S. horridus, 

 but, without an opportunity to examine the types or specimens from 

 the type localities, it seems best to use a name of unquestionable 

 applicability. 



15. Cnemidophorus deppii lineatissimus Cope. 



Two specimens (C. A. S., 3,344, 3,343) taken at San Bias, Jalisco, 

 in October, 1894, seem typical of this lizard. 



16. Cnemidophorus gularis B. & G. 



A lizard caught at Guaymas, Sonora, May 12, 1892, is identical 

 with Arizonan specimens of this species. 



17. Cnemidophorus mariarum Giinther. 



A large number of lizards from Mazatlan, San Bias and Tepic 

 seem to be identical with Gunther's specimens from the Tres Marias- 

 Islands. Whether they are also identical with Cope's C. communis 

 and Peter's C. mexicanus I have not been able to decide. 



The upper lateral light lines are much farther apart than in C. 

 gularis, causing the specimens to bear some resemblance to C. sez- 

 lineatus. 



18. Sympholis lippiens Cope. 



One typical specimen (C. A. S., 3,127) of this rare snake was 

 taken at Tepic in October. 



19. Bascanion flagellum frenatum Stejn. 



The cross-bars on the neck are rather faint in a snake of this sub- 

 species (C. A. S., 3,412) which Mr. Bryant procured at Hermosillo, 

 Sonora, in May, 1892. This snake was brought back alive and died 

 in San Francisco in October, 1892. 



20. Basoanion semilineatum Cope. 



This racer was taken by the Academy's collectors at both Tepic 

 (Nos. 3,131, 3,132) and Mazatlan (No. 3,391) in October. 



21. Bascanion lineatum Bocourt. 



A single example (C. A. S., No. 3,130) with one hundred and 

 eighty-four gastrosteges, one hundred and twenty-one urosteges, and 

 scales in seventeen rows, was shot at Tepic in October.
