6 Green's 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; 1S25. 



Salamaxdea 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,,
