Deducting tlie Arkansas species found in eastern 

 Texas (71) leaves 106 species. After carefully reviewing 

 the work of recent collectors in eastern and northeastern 

 Texas, we feel safe in saying that the greater per cent 

 of future additions to the Arkansas list may be expected 

 to come from the Austroriparian fauna of Louisiana and 

 the Ozarkian fauna of southwestern Missouri rather 

 than from the central of western Oklahoma and the 

 Sonoran of Texas. Such forms as Cnemidophonis 

 gularis, Sceloporns consohrinus and Thamnopliis eques 

 are merely outrunners from the Sonoran, whose rela- 

 tionships are not yet fully understood. Probably few 

 true Sonoran species range east of the 98th meridian of 

 loncritude in Texas.

Southern Missouri, eastern Oklahoma, northern Lou- 

 isiana, and northeastern Texas. No definite localities 

 for Arkansas, but it probably inhabits the entire State. 



Family Desmognathidae. 



2. Desmognathus brimleyorum Stejn. Brimley's Sala- 



mander. 



This species is abundant in the type locality, Hot 

 Springs (Combs and Hurter) and at Little Rock (Ilur- 

 ter). At Little Rock liurter placed examples of this 

 species and Spelerpes mnltiphcatus Cope in the same 

 bucket just as he captured them. On returning to his 

 room, he discovered that the Spelerpes had all been de- 

 voured by the hungry Desmognathiis.
