Davis 1946 Lipilo fransu 42. Guadalajara Jalisco, Mex. to Sierra de Tapalpa, 15 mi. W of Sayula, 7450 ft Jalisco, Mex. Aug. 3, 1946 is almost completely dry at present. The country on the way to Sayula is arid tropical. Groove- billed Anis were noted on the way. There is a great deal of Ima cactus, some scattered candelabra cactus, maguey, and many corn-fields. Leaving Sayula on the road to San Gabriel we went up a fairly steep grade. The country on the way up is mostly low scrub, with scattered deciduous trees. The first oaks were noted at 5850 ft. At 6500 ft. the plant association included oaks, pines, mimosa, and maguey. The first Brown Towhee noted after leaving Sayula was 13 miles from town. After this they appeared commonly, and one was collected a short distance from where we made camp. Although towhees were not seen for some distance up grade from Sayula, there is nothing to prevent their occurrence from Sayula up to the crest of the rise. The low scrub is broken by cultivated fields in many places, and this high country is not of barrier nature. Towhees are common higher up. Certainly the population from Lake Cha- pala is said to Sayula is continuous, and it is hard to conceive of an endemic race being found between C. Gymen and Jacoalco.
