(D.S.) or I returned government car after work. Evening clear and mild. July 3 noted 3 toads tadpole and one Hyla scavenging on a single dead Hyla toad 11:00 A.M. Previous to this I have only noted carnivorous feeding by tree-frog toads. Algal supply placed in aquarium 3 days ago has been eaten, so that scavenging may be forced secondarily on the toads. The toad toad one average body length 11.5 mm., total length 22 mm. Feeding toads were near surface on top of a rock, water 1/2" deep. The dead toad may have been dragged up from the bottom to its position on the rock. July
