Journal Hafner, U.S. 1977 En Route: Pachuca, Hidalgo to Llera, Tam., México. 15 August Awoke early and continued north on Hwy 85. A very long winding road finally brought us to Tamazunchale on the east side of the Sierra Madre Oriental. We bought 2 bowls near this town for about 20 pesos each. The road leveled-off at this point and we continued north on Hwy 85 through Ciudad Valles to the area of Llera about 40 miles S of Ciudad Victoria. We took a dirt road toward the west that brought us to the locality: 13 km S, 1 km W Llera, 450 m. Tamaulipas, México. At this locality we noted gopher signs in the cane and bananas (mostly in the cane). We set-out several sets apiece and monitored them until well after dark. JCB finally captured one Heterogeomys alive at about 2030. We packed-up and headed north where we found a nice motel in Ciudad Valles. Ciudad Valles, Tamaulipas, México. 16 August We arose and taxostyped the Heterogeomys. After preparing the skin, we packed-up and drove NE on 180 (101) toward Brownsville, Texas
