Hendrickson 1950 June 20 (cont.) Journal Derrhontes Buzz. Note on Dera & Craxidophorus "voices" Dana were heard calling at two diff. localities. The second time, when the calls were heard for an extended period, one was traced to an area of about 2 ft. diam. without sighting the exact source of the calls. Intensive search (visual) followed by rock-turning revealed one small Dana and no other amphib. The local boys who were with me identified the calls when first heard as those of this frog. They apparently knew it well. The sound is a subtle, but penetrating tol... tol... tol... tol... which reminded me very much of the sound of spiced drope falling from a leaky faucet into a container I estimated the frequency of the calls at roughly 21/2/sec. / Three times during the day Derrhontes were seized in the hand unhurt or only slightly
