1. Ambystoma macrodactylum Baird 



Cope's A. epixanthum was described from specimens col- 

 lected near the head of South Boise River, on the south side of 

 the Sawtooth Mountain range, Idaho. Sixty-four salamanders 

 from Boise County seem to us to be indistinguishable from 

 numerous specimens of A. macrodactylum collected in Wash- 

 ington, Oregon and California. Cope, himself, recorded sal- 

 amanders from Montana under the latter name. Of our speci- 

 mens, twenty-one were secured at Payette Lake, Boise County. 



*Species which the Academy has not yet received from Idaho.
