All these salamanders have been found by the 

 writer to be fairly abundant, except the three species 

 given below: 



Amblystoma jeffersonianmri Green, is my latest 

 find. One specimen, only, was taken at Silver Lake 

 Park, near White Plains, N. Y., about 1,000 feet 

 from the lake, on a hill in the woods, at an altitude 

 of about 100 feet from the level of the lake. The 

 salamander was under a large flat rock, exposed to 

 full sunshine, in soft, perfectly dry, almost dusty soil. 

 It was covered with dust, but upon being handled,

 typical coloring. The color is dark brown above, 

 with small, light blue spots on the sides, limbs, and 

 sides of the tail; undersides bluish-black to gray. 

 Length 4 3 /i inches from tip of snout to tip of tail.

 jaws is inconspicuous, as is the lateral parotoid fur-

 little shorter than the body and head. It is oval in 

 cross-section in the middle .... without any ridge 

 or crest .... it becomes more and more compressed 

 towards the tip. The limbs are largely developed and 

 the toes very long. The digits are cylindrical and
