AMPHIBIANS AND REPTILES. 103 
squeaky sound was heard occasionally, though only during the 
breeding-season. They were much more abundant than Hyla 
pickeringti, After the eggs were laid Dr. Abbott found them to be 
quiet, not making any noise till spring, when they would seem to 
disappear till about the middle of July or the first of August. How- 
ever they would not then resume their noise. I have heard them in 
various places, more or less regularly, from spring all through 
the summer, and on several occasions in Dr. Abbott’s own 
meadows. It may be stated that in my experience their call ap- 
pears to be variable. ‘The usual note is not heard at a great dis- 
tance, and is described by one writer as exactly imitated by strik- 
ing two marbles together, first slowly, then faster and faster, for a 
succession of about 20 to 30 beats. Perhaps the rattling of cast- 
anets would be a better suggestion. The animals live in the 
grass and take enormous leaps, seldom if ever frequenting trees 
or bushes. When disturbed they usually swim or leap, but rarely 
sink below the surface of the water, and if scen.are easily secured. 
The species varies much in color without regard to locality. 
Some are very bright and others pale. Mr. H. Walker Hand 
and myself found them abundant in the fresh waters, adjacent to 
the salt-marshes at Cape May, in April of 1903. I have examined 
many examples from the various localities already mentioned, 
besides others procured by Mr. Samuel N. Rhoads from White 
Pond, Swartzwood Lake, and Cedar Lake in Warren county 
taken in October, 1895, Culver’s Pond in Somerset County taken 
in October 1894, and Sussex County. Examples from New Jer- 
sey procured by Dr. Pickering have also been examined. Octo- 
ber roth, 1906, I found a number of examples near Trenton 
Junction.
