Lake Omega Zoo; N of St. San Miguel, El Salvador Feb. 7, 1942 After dark. Gealy, who was with me, caught a gecko (1188) in some dead leaves. It is not Clocypx mitratus, but smaller, darker, lacking the con-trasting white and dark brown pattern, and has prominent pads at the ends of the digits, whereas C. mitratus has tapering digits. Collected a Bufo valliffs (1187) in some leaves by the side of the trail. Stirton went night hunting, and caught a ring-necked snake (1186) for me. Although it was caught in the grassland of camp, it was in some dead leaves under a couple of trees. Although the habitat does not correspond exactly to the rock and leaf-littered forest floor in which the others have been taken, the presence of dead leaves seems to indicate a preference for this type of cover on the part of this snake. Feb. 8, 1942 Hunted west of camp in a.m. Shot a Richardson's ledeater (1190) in the grassland near camp. In the Imiiose thickets about 1 1/2 min. W of camp collected a Yellow Warbler (1191) and a Myiarchus tyrannulus (1189). In the open woodland of the Imiiose scrub took a Blue Tanager (1193) as it fed on green berries on a low shrub. Took a Mexican Ground Dove (1192) from a dense thicket near a slough leading to the Rio San
