A SALAMANDER NEW TO THE DISTRICT OF 

 COLUMBIA. 



BY LEONHARD STEJNEGER. 



I wish to place on record the capture of a species of Amby 

 stoma additional to those enumerated in Prof. W. P. Hay's 

 4 List of the Batrachia and Reptiles of the District of Colum 

 bia" (Proc. Biol. Soc., Washington, XV, 1902, pp. 121-145), 

 viz : Ambystoma maculatum (Shaw). A large specimen was 

 caught at Twining City, D. C. on Oct. 19, 1902, by Mr. A. E. 

 Thorn, and is now in the National Museum (No. 30,906). 



Ambystoma maculatum is usually known as A. punctatum 

 (Linnaeus), being the Lacerta punctata of the twelfth 

 edition of the Sy sterna Naturae. This name was preoccupied 

 by Linnaeus himself in the tenth edition for a true lizard, now 

 known as Riopa punctata. Its use is therefore precluded. The 

 next name in time is Bechstein's Salamandra palustris, but this 

 name was also preoccupied the year previously by Schneider 

 for the female yellow-spotted Salamander of Europe. Shaw's 

 Lacerta maculata is the next name in time, and is apparently not 

 preoccupied. These names are absolutely equivalent, being all 

 based on Catesby's "Car. 3, p. 10, t. 10, f. 10." The synonymy 

 of this species, consequently, will stand as follows :
