This form resembles the C. s. sexlineatns more than any other, but 

 always possesses the postantebrachial plates and more numerous femo- 

 ral pores, which range from eighteen to twenty-two. Occasional speci- 

 mens are, however, intermediate between the two. Its range is the 

 Sonoran region. 



Under this subspecies must be placed four of the series of forms 

 which I described in my paper on the reptilia of Chihuahua as sub- 

 species of the C. sexlineatns ' in the following language, two of the 

 forms (IS'os. 5, 6) being the C. g. scalaris Cope: 



1. Six longitudinal narrow stripes with unspotted interspaces.. C. g. gularis (young). 



2. Six stripes as above, tbe dark interspaces with small white spots. . C. g. gularis vcrus. 



3. Six stripes as above, wider and very obscure ; small obscure spots, 



C. g. gularis ohsoJetiis. 



4. Six stripes as above, but wider, and the spots enlarged so as to be continent occa- 



sionally with the light stripes 



"Of the above forms all are numerously represented in the collec- 

 tion. The modiflcation of the color pattern described is not entirely 

 due to age, as some of the largest specimens belong to Nos. 2 and 3. 

 Nevertheless small specimens predominate in the No. 1, and No. 4 pre- 

 sents a good many small specimens." The specimens enumerated are 

 as follows : ^ 



Subspecies No. 1; Cat. Nos. 14,236-41-49-69; 14,305. 

 Subspecies No. 2; Cat. Nos. 14,231-41,305-308. 

 Subspecies No. 3; Cat. Nos. 14,231-50-308. 

 Subspecies No. 4; Cat. Nos. 14,241-50-302-5. 



These forms are not sexual, as several of them include both sexes. 



Not having been fully persuaded of the distinction between the 

 C. fessellatus and C. sexUneaius series, I used the name G. s. tigris for a 

 ''Sixth subspecies" of the above table. The name was, however, mis- 

 applied, although the color pattern is identical with that of the C. tes- 

 sellatus tigris Baird and Girard, with the exception that there are 

 traces of six stripes instead of only four. The smaller specimens

-The numbers are attached to lots, by the recorder, and not to individuals, and 

 are hence sometimes duplicated.
