-66 REPORT OF NEW JERSEY STATE MUSEUM. 
of D. fusca, From the ochrophea stage of the latter it may be 
distinguished, as already pointed out by Cope, and as I have 
further suggested in comparison with Plethodon erythronotus, 
by the absence of a broad light dark-edged oblique streak pass- 
ing down from the eye posteriorly behind gape. From both of 
these salamanders bislineatus is seen to be more slender, with a 
longer slender tail, and the belly yellow. ‘This species is perhaps 
most always found in the upland country of the state. It is 
largely aquatic in its habits and is frequently to be found about 
springs, brooks or other clear cold waters, usually under wet 
stones. It is only to be found, however, in the shallow waters, 
and not in deep pools. Frequently one will find all stages of Des- 
mognathus fusca, some with backs as red as some of Plethodon 
erythronotus, and Spelerpes ruber, all in the same locality, though 
S. bislineatus in my experience is usually the least abundant. Mr. 
Witmer Stone states that it is rather common. In my experience 
it is fairly frequent in some localities. It is very active, 
scampering or wriggling away with great energy. Its meta- 
morphosis is prolonged, sometimes remaining in the larval 
state till nearly grown. Dr. Abbott found it about Trenton.
