Hurter and Strecker—Amphibians and Reptiles of Arkansas. 15 
from Arkansas and Oklahoma. Cnemidophorus gularis 
B. & G., Sceloporus consobrinus B. & G., Thamnophis 
eques 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 
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: 
AMPHIBIA. 
Desmognathus brimleyorum Stejn. Ambystoma jeffersonianum Green 
Spelerpes multiplicatus Cope Amphiuma means Linn. 
Hemidactylium scutatum Schlegel §Necturus maculatus Linn. 
Ambystoma annulatum Cope Rana palustris LeConte 
Hyla pickeringi Holbrook 
REPTILIA. 
Chrysemys dorsalis Agass. Tropidonotus sipedon sipedon Linn.

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 227 
Lizards 457 
Snakes 70} 177 
* Based on Strecker’s List (Proc. Biol. Soc. Wash. 21 : 53-62) with addi- 
tion of Rana clamitans which has since been found to occur_in northeastern 
Texas. 
+ From Strecker’s Check-List, which is now in press.
