1927 P.G. San Jose del Sacare, Dept., Chalatenango, Salvador cought the closely related form No. 12695. Both specimens were taken in the same association. After running the trapline before breakfast, I went with Mr. von Rossem far over the pine ridges to the west of camp. Nearly all the trees in that region are bent to the south. This condition is obviously due to the strong trade winds that sweep across Honduras and Guatemala from the north. It was along one of the pine ridges that we saw two of the large gray squirrels, but was shaking the other down a tall pine when we saw them. We shot one, No. 12717, Sciurus, but the other escaped. About 5: P.M. I struck out north of camp with fourteen large snap traps to set in a stream for Rheomys. This stream was very rocky with many fairly large pools. The stream bed was wide and devoid of brush. On the way back to camp I saw bats flying at 6:10 P.M.
