THE GRAY SPOTTED OR VISCID SALAMANDER. 125 
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 elass 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 fhe 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 branchie, but lose them early, that is, in 
about three or four days aiter hatching. The little ones usually have 
the same markings as the adult, but are often bright red, spotted with 
black. The younger larvee 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.
