6' Greenes new species of Salamandra, 
stripes on the back are imperceptible, and the Whole upper 
surface appears of a uniform brownish colour — sometimes 
these stripes cover the whole upper surface — sometimes a 
broad reddish stripe extends along the back from the snout 
to the extremity of the tail — in some specimens the umber, 
white, and yellowish spots are almost entirely wanting, and 
in others they are very numerous — -different localities almost 
always produce different appearances; yet, notwithstanding 
these differences, there is a strong family resemblance, and 
the species may be very readily identified. 
It may be worth while to notice in this place, that the 
length of the tail of the Salamander ought not to be relied 
upon as a distinct specific character — for the tail when it is 
re-produced after amputation, is perhaps never as long as it 
was before. I have an individual of the S. Intermixta, per- 
fect to all appearance, the tail of which is scarcely more 
than half the ordinary length. 
The skin of this animal, when properly prepared, forms 
a most splendid and interesting object for the microscope. 
This species of Salamander I first indicated in the Port Folio 
for August, 1825. 
Salamandra Glutinosa Var. 
In addition to the remarks on this animal in the Journ. 
of the Acad. Nat. Sciences, I have to state that there are 
some striking varieties of it I am informed by a friend 
that he detected one in which the white spots had a silvery 
lustre, very much as if minute pieces of silver leaf had been 
scattered over the skin. In Washington county. Pa. these 
animals are exceedingly abundant. Near the Chartier's 
creek, in shady situations, almost every old log and loose 
stone conceals numbers of them. The white spots on the 
sides and upper part of the body are variously arranged — 
in some they are pretty regularly scattered over the whole^
