San Juan Mine, 7 hrs min. E Metapan, Dep't. Santa Ana, El Salvador April 3, 1942 A O on the outside of the group would enter into an amplexus with a O in the heart of the group, but 2 O's never held this position for longer than 2 or 3 seconds. We watched this performance for some 25 minutes, And when we left the other 5 were still trying. Almost every foot had at least one individual, usually more. At least 10 to pairs were seen in amplexus. April 4, 1942 Reitz + I caught 2 Brownheads a piece. They are evidently the same species as that at Monte Triste, And are quite common in the grass & scrub here. Reitz has tried noosing lizards but with indifferent success. Ameiva is built with the head tapering smoothly from the body, so that when the lizard is lifted from the ground, the loop of thread slips over the head. One large yellow-spotted Ameiva was noosed and lifted from the ground 6 times without taking alarm. I finally hit it with a stick. Basiliscus vittatus is commoner here than anywhere I have been yet. They are in all the dry washes, and on the banks of same, in Agave hedges, & in flest & scrub. This was surprising since virtually all of the others seen before this were near water, but there is very little water here, and this lizard is abundant & very widely distributed. Saw two Ctenosaura compacta today -
