Paul DeBenedictis 1960 Rana pipiens Dec 28 31.1 m N. (by Mex 15) Ixtlan del Rio, Nayarit, Mexico --(tadpoles and eggmass) In a stream about 3 feet across and 6 inches deep flowing rapidly through an oak and grassy canyon Elvey found one eggmass, and I found another. The one I found was under the shelter of a large flat rock, kidney- shaped, about 243x1/2 feet in size, in about 6 inches of water. The eggmass was in a clump at calage in the crook of the "kidney," exposed to the sun. Many tadpoles swam around the eggmass, though none were hatching s. Teddy some some Electrodactylids here, and Gene got a Hyla axina.
