males with vocal pouch on either side; these being perfectly round 

 vesicles when inflated, and the throat not inflating. 



Voice: The call is like the blow of a hammer, usually repeated 

 3-6 times in rapid succession, or like wood choppers. 



Breeding: They breed from late April to mid-August. The egg- 

 mass is a plinth 3-4 inches (75-100 mm.) x 1 1/2 inches (38 mm.), 

 or it may be globular. The complement is small, 200-600 eggs. The 

 black and creamy white eggs are large and far apart. The egg is 1/16 

 inch (1.5-1.8 mm.), the envelope 1/ 8-1/4 inch (3.8-6.9 mm.). The 

 tadpole is large, 3 5/8 inches (92 mm.), dark in color with a few black 

 spots, its tail grayish with a row of large spots in the upper crest. 

 The tooth ridges are 2/3 or 1/3. After a tadpole period of 1 year, they 

 transform in early spring at 1 5/1 6-1 1/4 inches (23-31 mm.). 



Notes: On May 22-23, J 9 2 4? we heard a few males croaking on the 

 south side of the west point into the lake at Lakehurst, N. J. It was 

 noon and the sun was shining. Here in the sphagnum-heath edge, we 

 caught 4 adults, two females and two males. As we waded along we 

 would see them sometimes wholly out of water or at the lake's edge. 

 Usually they leaped into the water and hid under the vegetation mat 

 or quickly came up under a water-lily leaf or swam some distance and 

 then poked out their heads. Most of the males were out in the deeper 

 water. 



June 8, 1929. Raining . . . The frogs were in mid-lake in the 

 matted vegetation. The boys, Everett and Whittemore Shinn and 

 R. D.Anderson, went out in the canoe, and caught some for us with a 

 long handled dip net. 



In coloration R. virgatipes looks most like R. grylio. In adult size 

 it is more like R. septentrionalis but smaller or is possibly like a small 

 R. catesbeiana. At Lakehurst Lake it reminds one of the water prairie 

 form, R. grylio; in the sphagnum strands and thickets of the Okefino- 

 kee it reminds me of the peat lake species of Canada or beaver-lake 

 thicket form of the Adirondacks, namely, R. septentrionalis. In egg 

 mass it is most like R. septentrionalis, but in individual eggs unlike 

 R. septentrionalis, R. clamitans and R. grylio because it has no inner 

 jelly envelope. The individual eggs, are more like the eggs of the film 

 species R. catesbeiana, but the jelly is firmer. The tadpole reminds one 

 most of R. grylio in coloration, but it is more of the R. clamitans type. 

 Like all of the R. clamitans and R. catesbeiana type it winters over as 

 a tadpole. It transforms at a size near that of R. clamitans and may 

 have a larger tadpole than that species. Therein it approaches R. 

 catesbeiana, R. grylio and R. septentrionalis.
