Green's new species of Salamandra, 
SalAMANDRA JeFFERSONIANA CAUDA MEDIOCRI COR- 
PORE SUPRA FUSCO7 MACULIS CGSRULIIS SUBTUS FUSCO. 
Blue spotted Salamander — Length about 7 inches — ■ 
tail as long as the body, tapering, slightly compressed and 
pointed — head remarkably large — eyes entirely black, re- 
mote and very prominent — nostrils large — skin a light 
brown colour, rather darker above than beneath, with beau- 
tiful azure blue points scattered irregularly over the whole 
surface — on the upper part of the tail and legs, these points 
are grouped so as to form small blue spots; but on the under 
part of the body and along the spine, they are scarcely per- 
ceptible — anterior feet four toed — posterior, five toed — all 
the toes remarkably long, and terminated with a callosity. 
Cabinet of the Maclurian Lyceum — my collection. 
This animal was found in the marshy ground near Char- 
tier's creek, in the vicinity of Jefferson College at Cannons- 
burg, Pa. It is remarkably well proportioned, and creeps 
with much facility on land, being greatly assisted in its mo- 
tions by the peculiar construction of its feet, the toes of 
which are much longer than those of any other species of 
Salamander with which I am acquainted. Bath the pupil 
and the iris of the eye are entirely black; and I observed 
on exposing the head of the animal to the sun, that a thin 
film or nictating membrane, originating from beneath the 
lower lid, quickly rose and covered about one half of the 
cornea, thus protecting the eye from intense light. Though 
this remarkable and delicate structure in the anatomy of 
these animals has never to my knowledge been noticed be- 
fore, I have little doubt that it is common to the whole 
genus. The large size of the animal enabled me on this 
occasion to detect it. In the above singular oi^anization 
of the eyes, the Salamander is allied to the Owl and some 
other animals.
