Davis 1942 W slope Mt. Tacaguate, 4600; dep't. Morazan, El Salvador. Jan. 14, 1942. at the upper edge of a cornfield. Jan. 15, 1942. Picked up traps. 2 Oryzomys (1048-9) both taken in traps set by the stream edge. 1 small Oryzomys (1051) taken in a similar set. This specimen, and no. 1042, are of a dif- ferent species, and belong to the subgenus oligorygomys. Stinton took the first specimen and says that it is a new mammal for Salvador. The leithre (1050) was taken in the brush at the top of the cornfield. Two two species of harvest mouse have been taken here. One is very red + rather large, and seems to inhabit the rocks. Stinton says that it is a new species for the country. The individual I caught today was very red, but ra- thier small, + it is difficult to assign it to species. The Baromys (1054) was taken below the cornfield, in a trap at the water's edge. Inasmuch as these animals stick pretty well to dry cornfields and rocks, I imagine that this crossed individual had come down to the stream bedrink. The black peromyscus (1052) was taken at the stream's edge. The red leromyscus was taken in the brush at the top of the cornfield. Stinton and Thildebrand have found that the two species are quite sharply separated, and may come together, but rarely overlap. Two other peromyscous caught by the stream were black, and two others taken in the bush were red. Skimed p.m. Set out no traps today.
