probably opacum, but the March larvae and the eggs 

 were probably not. Pike contrasts the egg-mass 

 with that of A. maculatum, but not with that of A. 

 tigrinum, and possibly he had eggs of that species 

 as it is known to breed on Long Island, and lays its 

 eggs in the water in spring. 



Brimley, in the American Naturalist for 1896, 

 p. 500, says that at Raleigh, N. C, A. opacum lays 

 eggs in October and November, on the edges of dry 

 pools, where the larvae hatch quickly when the pool 

 fills with water. 



McAtee, in the Proceedings of the Biological 

 Society of Washington, vol. 20, 1907, p. 13, describes 

 the breeding habits in Monroe Co., Indiana. He 

 speaks of "nests in the ground near the surface," 

 which "contain from 50 to more than 150 eggs." 

 The larvae may reach a length of an inch while in the 

 ^gg, but they must have water to live in while com- 

 pleting their development. They transform in Feb- 

 ruary and March. 



In Copeia 8, July, 1914, Engelhardt says he 

 found larvae in June at Lakewood, N. J., in a locality 

 in which adults had been caught; these larvae were 

 one to one and a half inches long. 



In Copeia 28, March, 1916, Deckert speaks of 

 getting eggs with the adult on September 25, near 

 White Plains, N. Y., in the bed of a dried-up pool; 

 the eggs were separate from each other and covered 

 with dirt. They were kept in the debris for a day, 

 and on September 27, some were put into water. 

 These hatched on September 28; the larvae were % 

 inch long and front limbs were apparent. Other eggs 

 were kept in the deep debris until October 18, put in 

 water and hatched on October 19. 



Larvae, 2 inches long, were collected in April, 

 which transformed in June. 



Brimley (Bull. Elisha Mitchell Sci. Soc, vol. 

 32, no. 2, July, 1916), says that at Raleigh, X. C, the 

 habits of A. opacum differ from those of A. macu- 

 latum in that the eggs are not in gelatinous masses,
