Structure: "Femur and tibia and hind foot about equal, and half 

 the length of the body." (S. F. Baird, 1854, p. 60). 



Voice: A penetrating and grating it-it I 'it-it /is given many times 

 without a stop. "Its note resembles that of Acris in being crepitant, 

 and differs from the toned cry or whistle of the Hylae. It is not so 

 loud as the former and is deeper pitched; it may be imitated by draw- 

 ing a point strongly across a coarse comb, commencing at the bottom 

 of a jar and bringing it rapidly to the mouth; or, better, by restraining 

 the voice to the separate vibrations of the vocal cords, and uttering a 

 bar of a dozen or twenty vibrations, beginning with the mouth closed 

 and ending with it well opened." (Cope, 1889, p. 345). 



Breeding: They breed from February to May 10. The black and 

 cream eggs are in irregular loose jelly masses attached to the stems of 

 matted vegetation. The egg is 1/25 inch (0.9-1. 1 mm.), the single 

 envelope 1/8-1/6 inch (3.2-4 mm.). The envelope in the mass be- 

 comes larger and irregular. The small tadpole, 1-1 5/16 inches (25-33 

 mm.), has the tail medium, with tip acute or acuminate, and is black- 

 ish or olive in color with bronzy belly. The tooth ridges are 2/3. After 

 a tadpole period of 50 to 60 days they transform until mid-June, at 

 5/16-1/2 inch (8-12 mm.). 



Notes: April 4, 1929, Carlisle, Pa. We found a surface pond at the 

 edge of town, and heard and caught 3 Pseudacris here. 



April 6. We started up North Mountain, Carlisle. . . . Just before 

 Indian Springs, we heard a great chorus. . . . On the hillside, beside 

 the road in an open field was a springy area. . . . We saw two little 

 fellows with their amber throats so distended that they showed from 

 the rear. They were sitting in the mat of vegetation, a little ways from 

 a tussock, with their heads held up vertically, above the water. The 

 stream area was fairly deep but filled with a mat of grassy vegetation. 

 We rolled this back a bit at a time and caught an occasional frog in 

 the tangle. The irregular egg masses were common in this mat. 



Detailed color description of a female from North Mountain, 

 Carlisle, Pa., follows: Upper part of head, back, fore and hind legs, 

 russet, hazel, verona brown or warm sepia. Under side of hind legs 

 benzo brown, drab gray or brownish drab. Under parts of body cream 

 color becoming slightly massicot^ yellow or napthalene yellow on 

 throat. Stripe down middle of back, stripe either side of median stripe 

 and faint spots on sides are black or chestnut brown, mummy brown 

 or sepia. Stripe through nostril and eye to shoulder and beyond warm 

 sepia or vandyke brown. Band around upper jaw extending backward 

 beyond shoulder; below the dark stripe is warm buff, cream buff, or 

 chamois. Iris, same color as vitta through eye, but dotted with mars 

 orange or burnt sienna. These predominate in the upper half giving 

 iris a "reddish" or "coppery red" appearance.
