" Under logs and rails in open woods at some distance from

9 Plethodon cinereus Green 



De Kay. Salamandra erythronota, the red-backed salamander, p. 75, 



pi. 16, fig. 38 



Three subspecies of this form are distinguished by Cope. 



a Plethodon cinereus cinereus, color, liver-brown, below 

 dirty white mottled with black, giving a "pepper and salt" appear- 

 ance, sometimes yellowish toward the head. 18 costal grooves. 



h P. c. e r y t h r o n o t u s . Form and structure similar to above 

 but back with a broad, reddish stripe. IS costal grooves. Resem- 

 bles Spelerpes bilineatus, but in that form the belly is 

 unspotted and there are fewer costal furrows. 



c P. c. dor sal is. Quite similar to c. erythronotus but 

 with only 16 costal furrows. Much rarer than the others. 



All these subspecies are entirely terrestrial and found under stones 

 and logs in woods. Eggs laid in a little package under stones 

 in damp places. The young possess gills when hatched, but very 

 soon lose them. The most abundant salamander, found every- 

 where, specially in the mountains. 



10 Plethodon glutinosus Green 

 De Kay. Salamandra glutinosa, the blue-spotted salamander, p. 81, 



pi. 17, fig. 42 

 Skin covered with a milky secretion. Black, usually with bluish 

 white blotches and specks ; head, body and tail continuous and 

 rounded. Much like A m b 1 y stoma jeffersonianum, but 

 has lighter spots and shorter digits. 14 costal furrows. Length 

 5-7 inches.
