Lupilo fuscus 44. Sierra de Tapalpa, 15 mi. W of Sayula, 7460 ft., Jalisco, Mex. Aug. 5, 1946 Collected 2 adult males, both solitary, silent birds. One was taken from a stone wall sur- rounding a large area of pasture and corn fields. The other was taken a short distance out in the field, as it sat on a hawthorn bush. Sierra de Tapalpa, 15 mi. W of Sayula, 7460 ft., Jalisco, Mex. To Guadalajara, 5200 ft., Jalisco, Mex. Aug. 6, 1946 Drove from our camp back to Sayula at about 10 a.m. The grade down to Sayula looks good for Brown Towhees. The oak-pine association drops out about half-way down, and a xero- phytic association comes in. There are numerous fields and small settlements all the way down, and this grade would certainly be no barrier between the Sierra de Tapalpa population and that of the Zacualco-Sayula Valley. From Sayula we drove to Ciudad Guzman, formerly called Zapot- lan, and the type locality of P. F. Jenebrosee Van Rossem. The road out of Sayula leads east about 3 1/2 miles, and then turns south. A Brown Towhee was seen at this point. 4 mi. from the turn-off south we reached the crest of a ridge at 5200 ft, 500 ft above Sayula. This ridge does not consti- tute a barrier to P. fuscus. 5 1/2 mi. past the crest of the ridge Brown Towhees were noted. 11 mi.
