CHECKLIST OF REPTILES OF MEXICO 215 



STATE LISTS 



The accompanying lists have been constructed in the same way as 

 those for the snakes (U. S. Nat. Mus. Bull. 187, 1945, pp. 202-203) 

 and amphibians (U. S. Nat. Mus. Bull. 194, 1948, pp. 100-101). 

 Table 2 shows for each state and each of the indicated groups, first, 

 the number of forms recorded; second, the number of genera repre- 

 sented (these two numbers separated by a diagonal line) ; and third, 

 the relative position of the state (so far as number of forms is con- 

 cerned) as compared with other states (this number in parentheses). 

 The lists of snakes and amphibians have been brought more or less 

 up to date by inclusion of the additional forms defined and recorded 

 by various authors such as Blair, Bogert, Burger, Conant, Klauber, 

 Smith, Tanner, and Taylor (see Univ. Kansas Sci. Bull., vol. 33, 1950, 

 pp. 313-380, for references).
