TWO NEW SALAMANDERS OF THE GENUS 

 DESMOGNATHUS. 



BY E. R. DUNN. 



Haverford College. 



The following descriptions of one new species and one new 

 subspecies of Desmognathns are published in the course of a 

 revision of the genus now in progress. 



Desmognathus monticola 8p. nov. 



Type from Elk Lodge Lake, near Brevard, North Carolina, altitude 

 about 3000 feet; No. 38,313, adult male, U. S. National Museum; col- 

 lected July 13, 1908, by Ronald and Emeline Tipping. 



Diagnosis. — Vomerine teeth always present. Parasphenoid teeth usually 

 confluent anteriorly. Legs stout, 3 intercostal spaces between appressed 

 toes of adult. A distinct color pattern. Belly uniform, usually light. 

 Transformed specimens, total length, 30-135 mm.; length of head and 

 body, 17-64 mm. 



Description. — The vomerines form two short slightly arched series 

 which approximate each other in the median line. The parasphenoids 

 are usually confluent in front. They are long narrow series and are well 

 distant from each other save in front. Their distance from the vomerines 

 is about equal to the length of one of the vomerine series. The relative 

 shape of the tail is about as in fusca; the relative length is greater ; it is 

 not flattened as in guadramaculata. The legs are stout. In young speci- 

 mens the appressed toes are separated by 2 costal interspaces, in adults 

 by 3. The length of the head is from 4-4^ in the length of head and 

 body. The head width is from 5-6 in the length of head and body. This 

 is the second largest form of the genus with medium head and body, 

 long tail and medium legs. The skin of the head is sometimes rugose as 

 in guadramaculata. The costal grooves are 13-14. There is always a 

 tubercle in the anterior angle of the eye. 



The color of this form is much like that of fusca, but shows certain
