Kerdelison 1950 Hyla crepitans Oct. 19 5 km N. Villavieja, 1400 ft., Hula, Colombia, S. A. I found one individual sitting in shallow water amid rank grass in the berona patch 5 of camp. Dr. [illegible] found one up in a plant (see his notes). The call is a harsh, intermittent, rasping one. The animals seemed to respond to my attempted vocal imitation of the sound - a combined throat-clearing and low vocal sound production. Oct. 21 One individual found about 3 ft. up in a bush beside a pool in the quebrada 5 of camp. Another found about 1 ft. up in a similar bush about 15-20 ft. away. Both individuals were heard calling. Oct. 22 One of Museum specials set near pool in quebrada 5 of camp (same pool mentioned in account of this species for Oct. 22) contains a pair in amplexus. The female was had extruded some eggs (under the pressure of the trap bar) Oct. 24 A tadpole (hind legs external), probably of this species, was brought in by Porico and Paulino with a collection of small fish from the quebrada 5 of camp.
