9 Plethodon "cinereus Green 

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



pi. 16, flg. 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 witli a broad, reddish stripe. 18 costal grooves. Hesem- 

 bles Spelerpes bilin.ea.tus, 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 stonBs 

 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.

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

 rounded. Much like A m b 1 y s t o m a j e f f e r s o n i a n u m , but
