THE AMPHIBIANS AND REPTILES OF 
ARKANSAS.* + 
JuLIUS HurRTER AND JOHN K. STRECKER, JR. 
The present list of Arkansas amphibians and reptiles 
has been compiled with a twofold purpose in view: (1) 
to place on record a number of species collected by the 
senior author, which have not been reported from the 
state previously; (2) to form as complete a list of these 
animals as our present imperfect knowledge of the her- 
petology of the state will permit. 
In the United States National Museum Collection are 
a number of specimens obtained by Marcy, Shumard and 
other members of the Red River Expedition. Some of 
these are labeled ‘‘ Red River, Ark.,’’ and ‘‘ Fort Towson, 
Red River, Ark.,’’ but were not collected within the limits 
of the present State of Arkansas. 
Such species as Bufo cognatus Say, Thamnophis mar- 
ciana B. & G., Heterodon nascius B. & G., and Crotalus 
confluentus Say are members of an entirely different 
faunal region and are not likely to range east of central 
Oklahoma. Ruthvenj has called attention to the fact that 
Oklahoma examples of Thamnophis radix B. & G. are 
hard to distinguish from 7. marciana. Examples of 
marciana from north-central Texas are not typical, and 
it is extremely doubtful whether this snake occurs north 
of Texas. . 
Fort Towson is situated in southeastern Oklahoma. 
Probably all of the species collected at this station will 
ultimately be found in southwestern Arkansas. __
