NOTE.S ON SOME SALAMANDERS AND LIZARDS OF 

 NORTH GEOROIA 



The following salamanders and lizards were 

 observed at Thompson's Mills, Gwinnett 

 bounty, north Georgia, during the summer 

 of 1908. 



Among the batrachians of the order Uro- 

 dela, the following salamanders were found. 



I'lolhodon gluMnosun (Green). This is a 

 thick, stout-bodied, nearly cylindrical species, 

 and is capable of secreting a viscid, milky 

 juice, which has given it the name of the 

 sti(;ky salamander. Specimens found at 

 Thompson's Mills, Ga., in life, were dark 

 blui.sh slate above, lighter or paler on the 

 belly. The back and head were thinly 

 sprinkled with tiny, grnyiah-white dots, with 

 a few whitish or grayish dots beneath, mainly 

 on the throat. The sides wore mottled with 

 grayish, forming an almost continuous band 

 to the end of the tail. Length 5^- inches. 

 Several specimens of this salamander were 

 found at the above locality, all beneath logs 

 and the bark of decayed, fallen trees, in 

 .shady, damp woods. This salamander is ter- 

 restrial in its habits, and occurs in the ex- 

 treme north as well as throughout the south. 

 It is not uncommon at Thompson's Mills, Ga. 

 Tho red salamander (Spr.lerpp.n ruher 

 Daudin). At maturity this is a thick, plump, 

 short-bodied species, with small, weak legs. 

 Its skin is clear, smooth, without glands, but 

 besprinkled with shallow pits.

The specimens found at Thompson's Mills 

 wore 4,| to 5 inches long. In living specimens 

 tho coloration above was brick-red, very much 

 paler (or pinkish) on the belly. The back 

 and head were thickly and uniformly 

 sprinkled with black dots about tho size of 

 pinheads. Along the sides these dots became 

 much smaller and more scattered, and were 

 completely wanting along a line drawn along 

 the sides connecting the outer attachment of 

 the legs. The legs were of the same color as 

 the back, and finely dotted with black. 



This pretty salamander also ranges over 

 the eastern portion of the country. At 

 Thompson's Mills, I found only two individ- 

 uals, both beneath rotten logs in hilly woods. 

 This species is of more aquatic habits, which 

 probably accounts for the fact that an exami- 

 nation of hundreds of rotten stumps and logs 

 in tho upland woods yielded only two speci- 

 mens. 



Spelerpes guito-lineatus (Ilolbrook). This 

 is a very pretty, slender and elongated ani- 

 mal, with a slender, compressed tail, longer 

 than the body. Living individuals which I 

 have found at Thompson's Mills showed the 

 coloration described as follows. Beginning 

 just back of a line joining tho eyes, a narrow, 

 black stripe extended along the back bone, to 

 a point just behind the legs where it terminated 

 abruptly. Bordering this stripe on either 

 side, is a light grayish-brown stripe beginning 

 at the tip of the nose and extending just 

 above the eyes. These light, dorsal stripes 

 unite on the tail where the black, spinal stripe 

 terminates. On each side beginning from 

 the eye, another narrow, black stripe extended 

 to the tip of the tail, narrowing in proportion 

 as the tail becomes more attenuated. This 

 lateral black stripe was spotted with whitish 

 marks, and its lower edge outlined with white. 

 The belly was evenly and thickly mottled with 

 yellowish and light gray. I found only two 

 specimens of this salamander at Thompson's 

 Mills, both under a log in wet ground near a 

 brook. Their lengths were 7 inches and 6J 

 inches, respectively. This salamander is 

 mostly southern in its range.
