flay JBatrachians and ^Reptiles of D. C. 125 



short, almost rudimentary. Brown, chestnut, or purplish, bluish white 

 below; above there are numerous pale spots and specks; below there are 

 specks and spots of black. Length 3.5 to 4 inches. 



In the collection of the United States National Museum there is a 

 specimen labelled, "D. C.", but with data so insufficient as to throw the 

 locality in some doubt. During the collecting seasons of 1892 and '93 I 

 found the species occasionally under logs in the heavy woods between 

 Little Hunting Creek and the Mt. Vernon estate. 



4. Plethodon cinereus (Green). Ashy or Red-backed Salamander. 



Body elongate, slender, cylindrical; head small and short, snout 

 rounded; eyes large and prominent; limbs short and weak; toes short, 

 the inner ones rudimentary. Brownish black above; whitish or yellow 

 ish below, finely marbled with black; back often with a broad, brownish 

 red longitudinal stripe. Length 3.5 to 4 inches. 



Both the red-backed and brown varieties of this species are found in 

 abundance throughout the region covered by this list. They are to be 

 looked for under bark, leaves, logs, or flat stones in damp situations in 

 the woods. 



5. Plethodon glutinosus (Green). Slimy Salamander. 



Body cylindrical or somewhat depressed; skin smooth, shining and 

 very slimy; legs moderately developed, the toes short and depressed, the 

 inner on fore and hind legs small, but distinct. Black or blue-black 

 above, paler below; sides with numerous whitish spots about as large as 

 the eye. Length 3 to 7 inches. 



Rather common within our limits. I have found it most abundant 

 about Takoma Park and Mt. Vernon. 



6. Spelerpes bislineatus (Green). Two-lined Triton. 



Body elongate and slightly depressed; tail forming about one half the 

 total length; head rather narrow, snout short and rounded. Color yel 

 lowish brown or clear yellow above, pale yellow below; along each side 

 of the back there is a brown line extending from the eye to the tail. 

 Length about 3 inches. 



A very common species throughout the region. It may be sought un 

 der the stones or leaves near springs or small streams. 



7. Sperlepes guttolineatus (Holbrook). Holbrook Triton. 



Body somewhat flattened, elongate and slender, but stouter than in 8. 

 longicaudus; head flat, snout rounded; tail low and flattened, forming 

 more than one half the total length, tapering to a sharp point. Brown 

 ish yellow above, with three stripes of dark brown, one along the me 

 dian line and one on each side; tail dark brown with vertical, yellow 

 lines; the under surface is yellow mottled with brown. Length about 5 

 inches.
