CHECKLIST OF REPTILES OF MEXICO 5 



host of local residents, far too numerous to mention, who materially 

 augmented our collections and made our visits pleasant and successful. 



Inasmuch as we traveled chiefly by car, our routes are best followed 

 on a road map of Mexico. We entered Mexico on October 5, 1938, at 

 Ciudad Juarez, Chihuahua, and followed the Chihuahua-El Paso 

 highway southward to Vado (October 9). We then turned back to 

 Ahumada and followed a poor trail through Carrizal and Rancho 

 Nuevo to Progreso (October 10). We camped beside the Rio Santa 

 Maria about a mile southwest of Progreso for 5 days, interrupted only 

 by one hurried round trip to Casas Grandes for the benefit of a snake- 

 bitten cowboy. At this camp we were aided greatly by 10 or 15 

 cowboys who brought in material as fast as it could be preserved. 

 Our specimen containers full, we determined to go to the border to 

 ship specimens and hkewise to obtain higher wheels for the car (a 

 half-ton panel truck), with which we had encountered numerous diffi- 

 culties because of deep ruts and high centers. We left the Progreso 

 camp on October 15, passing through Casas Grandes and Ascencidn, 

 and reached Las Palomas the same day. After two days in Columbus 

 and Deming, N. Mex., we retraced our steps (October 20) from Las 

 Palomas to Casas Grandes. As the weather had become cool, we 

 continued southward along the road through San Buenaventura and 

 Carmen to the main El Paso-Chihuahua highway, thence southward 

 to Ciudad Chihuahua. We left there on October 27 for Torredn, 

 arriving October 29. We collected in the vicinity of Torre6n October 

 30 and 31, and on November 1 started for Ciudad Durango. We 

 could get no farther than Pedricena, however, and, after exploring 

 with little success a side road to Nazas, returned to Torre6n on Novem- 

 ber 4, We continued to San Pedro the next day and collected in the 

 vicinity of that town until November 10. After a side trip to Parras 

 off the Torredn-Saltillo highway, we made an attempt to find Jaral, 

 Coahuila, a locality made famous zoologically by Heller and Barber. 

 This turned out to be an abandoned ranch near Hip61ito, and, as no 

 likely habitat for the montane species recorded from Jaral appeared 

 to be nearer than 20 miles or so, we continued to Saltillo (November 

 14). We collected in the vicinity of Saltillo, Arteaga, and Mount 

 Zapaliname until November 17, when we left for Monterrey. 



On November 18 we arrived at Hacienda La Clementina (near 

 Forl6n), and we remained there until November 28, when we drove 

 to Laredo to ship another lot of specimens. We returned to La 

 Clementina on December 3 and left December 5 for Mexico City. 

 We stayed at Huichihuayan for several days, leaving December 9. 

 Our route, with brief stops at or near various towns, then led through 

 Mexico City to Tehuacan, Puebla, thence through Orizaba to Potrero 

 Viejo, Veracruz, where we arrived on December 11.
