THE GRAY SPOTTED OE VISCID SALAMANDER. 725 



curs in moist, woody places, hiding under stones and old logs, and when 

 these are upturned it, if alone, quickly disappears in the decaying wood, 

 moss, leaves, or earth ; but, if accompanied by its young, neither it nor 

 the little ones attempt to escape until touched. It climbs glass by ad- 

 hering with its abdomen, is frequently curled up on herbs, and, if dis- 

 turbed, springs away by a sudden uncoiling. They are very agile in 

 their motions, walk rapidly, run by sudden and irregular jerks, and have 

 been kept alive an entire year by allowing them dead leaves constantly 

 moistened. Their food appears to be small snails. When the young 

 are found, as a rule, they are accompanied, and often apparently being 

 fed, by their parents, but are occasionally alone. Their little ones, as 

 well as their eggs, occur under the moss and bark of decayed trees. The 

 latter are found in bunches of from six to eleven each, and individually 

 are about three-twentieths of an inch in diameter, and have been found 

 in June at Ann Arbor, Michigan, Fitchburg, Massachusetts, and in 

 August in the White Mountains. 



The young are supplied with branchiffi, but lose them early, that is, in 

 about three or four days after hatching. The little ones usually have 

 the same markings as the adult, but are often bright red, spotted with 

 black. The younger larvae are nearly white ; the older olive, with dark 

 spots. As age advances, the color deepens, becoming a brown, and very 

 old specimens often have a purplish tint.
