The Red-backed Salamander. Storer, Mass. Report, p. 245. 



Characteristics. Small. A distinct vertebral stripe, varying with age from scarlet to reddish 

 brown. Length 2-3 inches. 



Description. Body slender, cylindrical. Tail cylindrical, tapering towards the extremity, 

 where it becomes compressed, more particularly in the younger individuals, and pointed. 

 Snout obtusely rounded. Eyes small, moderately prominent. Nostrils lateral, near the snout. 

 Cervical fold indistinct. Legs feeble ; the fourth toe on the fore foot rudimentary. 



Color. Head above brownish ; chin and throat whitish, (according to Green, with a few 

 dots of crimson.) Sides dull white, thickly punctate with brown, and lustrous. Eyes black. 

 A broad vertebral stripe extending from the snout (occasionally from the occiput) towards the 

 end of the tail ; this stripe is of a deep or lighter red color, varying with age. In very young 

 individuals • 8 long, this stripe is of a brilliant scarlet or crimson. 



Total length, 3-0-3-5. 



Prof. Green, after a careful revision and comparison of his cinerea and erythronota, came 

 to the conclusion that the former was an aged individual of the latter, in which the dorsal 

 stripe had become obsolete. 



The Red-backed Salamander is a very numerous and widely distributed species. It is 

 among the first which appears in the spring, and I have seen it as early as the middle of April. 

 It runs with great rapidity among the leaves, in moist wooded districts, and conceals itself 

 under stones and decayed trees. It has been noticed by Dr. Blanding at Camden, South 

 Carolina, and by Mr. Say at Louisville, Kentucky. The most northerly limit of this species 

 observed by me, was on the islands of the Saranac lake.
