ALLEN: REPTILES AND AMPHIBIANS OF INTERVALE, N. H. 75 
17. Spelerpes bilineatus (Green). Two-lined Salamander. 
This slender little salamander is rather common under pieces of 
wood by the wet banks of little forest brooks, in much the same 
localities that Desmognathus fuscci inhabits. It is agile, and when 
once aroused, scrambles about with great rapidity. I found one in 
the crannies of a big log, lying across a small brook. On trying to 
capture it, it scrambled off the log, and, plunging into the water, 
swam quickly to the bottom and hid beneath a leaf. Like other 
salamanders, it will w r alk off the edge of a high box or table with the 
utmost unconcern, and strike the floor without suffering any appar¬ 
ent inconvenience. 
18. Plethodox erythronotus (Green). Red-backed Sala¬ 
mander. 
This is a common species under old logs in the damp beech 
woods, where there are one or two under almost every old log. 
These logs are, in most cases, sunken slightly into the ground, so 
that there would seem to be no means of egress at the sides, but 
there is usually a small hole or two leading from underneath the 
log down into the ground, and into these holes I have seen the sala¬ 
manders go when pursued. Whether they make these holes or not, 
I do not know, but they evidently use them to get in and out under 
the logs. 
The series taken at Intervale shows a considerable range in color 
variation. Some specimens are coal black on the sides, with a 
bright red stripe, and others are only lightly mottled on the sides 
with white and dusky, the dorsal being rather dull. In this species 
and the two preceding, it will generally be found that the part of 
the dorsal stripe just at the base of the tail is the brightest and 
most free from darker spots, and remains distinct longest when the 
animals darken with age, as in the case of Desmognathvs fnsca. 
19. Amblystoma puxctatum (Linn.). Yellow-spotted Sala¬ 
mander. 
After a rain, I obtained a single specimen of this species from 
under an old decaying: log: in the beech w r oods. Further search 
o o 
failed to reveal others. 
J\ T ote. Since writing the above a fine specimen of Thamnophis 
saurita has been taken on the intervales.
