N slope Mt. Tacaguate, 4600', Dept. Morgan, El Salvador Dec. 25, 1941. Bills from an open wire-walled shed right be- hind the ranch house (970). The ♂ has 2 large rose-colored blotches bordered internally with blue on the belly, which the ♀ lacks. [illegible] After lunch Stinton and I caught 1 Ameiva undulate in the garden in front of the ranch- house (967+968). One was a large adult, the other subadult. These lizards are very suggestive of Luvindophorus in their actions and methods of locomotion. Spent the afternoon on a ridge below the summit of the north slope looking for snakes, but saw nothing. In the evening took Joe Marshall to the spring where I had heard the owl the night before. We heard one owl which sounded like Otus asio, another which sounded like Otus dickopsis, and later, the same owl I had heard the night before. None of them, how- ever, could be called within shooting range. Dec. 26, 1941. Spent the morning on the peak of the north slope in the oak forest, and down the south slope a few hundred feet. There are supposed to be snakes of all kinds up here. I turned over logs and rocks, kicked apart brush piles, tore epiphytes from trees, and looked on the ground, up in the trees, in short covered the area thoroughly, both in the shade & the sunlight,
