 teepsie, N. Y., my friend, Dr. W. G. Stevenson, called my attention to

 such as Proteus, Salamandra, Triton, and Neoturus, Dr. Harlan first clearly elucidated its 

 characters, and as his name has become well-known its retention is deemed proper and 

 it is accordingly inserted here.

Cope, Joutn. Acad. Nat. Soi. Phila., 1866, vol. vi, expresses the opinion that this is a
