 eqnes Reuss, and Hyla versicolor chrysoscelis Cope are 

 southwestern forms, whose range is extended to central 

 Arkansas. Chorophilus occidentalis B. & G., Hyla squir- 

 ella Daudin, and Anolis carolinensis Cuvier are typical 

 Aiistroriparian species that are not likely to occur as 

 far north as Missouri. 



The following nineteen of the ninety species and sub- 

 species of Arkansas amphibians and reptiles enumerated 

 in this paper do not occur in eastern Texas :

The majority of these are eastern and southeastern 

 forms which find their western limit in Arkansas and 

 the eastern half of Louisiana. Sixty-three of the seventy- 

 one species and sub-species that occur in both Arkansas 

 and the eastern half of Texas are also found in the State 

 of Missouri. 



The number of species known to occur in Texas at the 

 present time is as follows: 



Tailed amphibians 10* 



Frogs and toads 40*
