crepitant, and differs from the toned cry or whistle of the Hyle. 
It is not so loud as the former and is deeper pitched. It may be 
imitated by drawing'‘a point strongly across a coarse comb, com- 
mencing at the bottom of a jar and bringing it rapidly to the 
mouth, or better, by restraining the voice to the separate vibra- 
tions of the vocal cords, and uttering a bar of a dozen or 20 
vibrations, beginning with the mouth closed and ending it well 
opened. (Cope.) 
This species I have not yet determined from within the

easily overlooked. The generic name Pseudacris will replace 
Chorophilus, of older usage, on account of priority,
