THE AMPHIBIANS AND EEPTILES OF new yo. 



ARKANSAS.* »otamc.-

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 sjDecies 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 Eed 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 Biifo cognatus Say, TJiamnophis mar- 

 ciana B. & G., Heterodon nascius B. & G., and Crotaliis 

 confluentiis Say are members of an entirely different 

 faunal region and are not likely to range east of central 

 Oklahoma. Ruthvent has called attention to the fact that 

 Oklahoma examples of Thatnnophis radix B. & G. are 

 hard to distinguish from T. 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. 



We have made liberal use of the Fort Smith records in 

 i>- a paper by Robert Baird McLain, entitled, "Notes on a 



uakden.
