02 SALAMANDRA LONGICAUDA. 



finders, distinct, and all nearly of the same length. The posterior extremities are 

 nearly twice the size of the anterior, with five distinct small toes. 



Colour. The head is lemon-colour above, and the chin and throat nearly the 

 same. The body above is of similar colour, with numerous small irregular black 

 spots; the thorax and abdomen are yellowish-white. The tail is coloured like 

 the back, but the black spots on it are lengthened into transverse bars. The 

 anterior as well as the posterior extremities are similar in colour above to the 

 back; below they are straw-colour. 



Dimensions. Length of head, 5 lines; of body to vent, 1 inch 10 lines; of tail 

 beyond the vent, 3^ inches: total, 5 inches 10 lines. 



Habits. Dr. Harlan places this among the aquatic Salamanders; and Professor 

 Green informs me that he has also observed this animal, which is one of the most 

 beautiful of our Salamanders, in water, and that its motions are exceedingly 

 graceful. There can be but little doubt, however, that it lives in general on land, 

 as its whole organization, teeth, tongue, &c, all place it among the true Sala- 

 manders; besides, Haldeman assures me that he has found it on land and at a 

 distance from water. Professor Green probably saw it in water during its breed- 

 ing season, for he further remarked that it is found on land in marshy places. 



Geographical Distribution. The Salamandra longicauda is found in most of 

 the northern parts of the United States. Dr. Smith has seen it in Massachusetts; 

 Professor Green has observed it near Albany, and at Princeton, New Jersey; 

 and Dr. Pickering informs me that they are found in the neighbourhood of Pitts- 

 burgh, west of the Alleghany Mountains. 



General Remarks. This is another of our Salamanders observed and first 

 described by Professor Green, of Philadelphia.
