San Juan Mine, 1/2 mi. SE Metapan, 1600', def't. Santa Ana, El Salvador April 3, 1942 between them and smaller individuals is that they are less nervous, & do not run very far when pursued, but remain in the same general area where first seen, whereas the typical Ameiva will often run 30 or 40 yards when pursued. These larger individuals too flew and root in the dirt in the same manner as Ameivas. They seem to feed on insects. Smaller Ameivas are everywhere, Bufois are uncommon. After Suffer worked along the stream bed about 150 yds. from the main house. There are a few pools of standing water; elsewhere the stream is completely dry, & the bed covered with small rocks washed down from above. Secured a toad, and 3 other Amphibia, of all different. Also a Bufo with prominent crests on the head; this toad is a sea green color dorsally. The same Bufo is here that we noted at Omego, which I tentatively identified as Bufo marinus (e.g. #1103). They utter the same powerful hill. In one large pool there were at least 30 of these toads, some in amplexus. One female swam out into the pool and was "approached" by about 6 m's, one of which went into amplexus with her. The other m's scrambled wildly to dislodge #1 and climb aboard. The seven toads were eventually clasped together in a clump, kicking, fighting, slashing. #1 never relinquished his hold. At times
