Description

Abstract. -- The original description of Heterodon nasicus Baird & Girard was based on one specimen (USNM 1272), which has since been lost. The holotype was credited to General Sylvester Churchill, who traveled from San Antonio to Presidio del Rio Grande (Mexican outpost downstream from Eagle Pass) and crossed the Rio Grande into Mexico. The type locality is here restricted to the Rio Grande, approximately 19 air miles (30.6 km) downstream from Eagle Pass, Maverick County, Texas. USNM 1249 from Eagle Pass is designated neotype of Heterodon nasicus. Other USNM reptilian species obtained under the same circumstances of collection are also listed. **********
