Hurler and Strecker — Amphibians and Reptiles of Arkansas. 15 



from Arkansas and Oklahoma. Cnemidophonis gularis 

 B. & G., Sceloporus consohrinus B. & G., Thamnophis 

 eques Eeuss, and Hyla versicolor chrysoscelis Cope are 

 southwestern forms, whose range is extended to central 

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

 ella Daudin, and Anolis carolinensis Cuvier are typical 

 Austroriparian 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 : 



Desmognathus brimleyorum Stejn. Ambystoma jeffersonianum Green 

 Spelerpes multiplicatus Cope Amphiuma means Linn. 



Hemidactylium scutatum Schlegel Neeturus maculatus Linn. 

 Ambystoma annulatum Cope Rana palustris LeConte 



Hyla pickeringi Holbrook 



Chrysemys dorsalis Agass. Tropidonotus sipedon sipedon Linn. 



Chrysemys troosti Holbrook Tropidonotus cyclopiura D. & B. 



Graptemys pseudo-geographica Coluber obsoletus confinis B. & G. 



LeSeur Diadophis punctatus Linn. 



Amyda mutica LeSeur Carphophis vermis Cope 



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* 



Turtles 22t 



Lizards 45t 



Snakes TOf 177 



* Based on Strecker's List (Proc. Biol. Soc. Wash. 21 : 53-62)>ith addi- 

 tion of Rana clamitans which has since been found to occur^in northeastern 

 Texas.
