be shy, quickly sinking out of sight among the aquatic vege- 
tation, after the manner of the sphagnum frog. They would 
usually sit more or less submerged near shore. ‘They uttered 
their cries at this season, according to reports, though we did 
not hear them. A large cluster of eggs was found submerged 
among the vegetation. Each capsule was rather elongated or | 
lozenge-shaped. During April of 1906 many frogs were croaking 
in the marshes of Mantua Creek tide-water. Masses of eggs were 
found on the 8th. They were probably this species, and were 
laid only submerged in large clusters over and attached to a few 
dead grasses. The frogs were shy and only approached with 
difficulty. They immediately stopped their noise if a bird flew 
over, or one approached, to sink quickly out of sight. Mr. David 
McCadden found this species on the point at Ocean City, August 
roth, 1906. His was a bright green example. Mr. Wm. J. Fox 
has observed them in warm weather at Sea Isle City. About 
Cape May they are the most abundant species on the edge of 
the salt-marsh in rain-soaked places, or fresh swamps. Mr. H. 
Walker Hand and myself first observed them in April of 1904, 
in company with Acris gryllus crepitans, Natrix sipedon, and 
— Chelopus guttatus. Most of those we saw then were dark like 
the Palermo examples. During October of 1906, about the 
same localities, Mr. T. D. Keim and myself saw a number of 
interesting variations. I have examined a number of examples 
from White Pond in Warren County taken in October of 1895 
(S. N. Rhoads), Cedar Swamp Creek (EF. D. Cope), Staffords 
Forge on June 2nd 1905 (P. Lorrilliere), May’s Landing in the 
fall of 1892 (S. N. Rhoads), Medford to the plains in Burling- 
ton County in June of r9g01 (Witmer Stone, H. L. Coggins and 
J. A. G. Rehn), and Bear Swamp in Burlington County on June 
r7th 1901 (W. Stone and J. A. G. Rehn). Dr. Abbott says its 
notes are metallic and that he has found it and R. catesbeiana 
in springs, near Trenton, in winter, where they were semi-torpid. 
They can leap further than any of our other species. Color from 
the dark olive or dusky examples already noted to brilliant grass-

muskin, and other places in the southern part of the state, are
