Tantilla gracilis Baird and Girard 

 r<7«//7/a ^ac/77\s Baird and Girard, 1853: 132. 



Holotype. — Stated to be University of Michigan Museum of Zoology (UMMZ) 3781 by 

 Kluge (1984), but the previous number given this specimen is USNM 4500, a number for a lot 

 of 1 1 specimens, two of which are still in the USNM collection, which specimens were not 

 likely to have been available to Baird and Girard (1853), inasmuch as this lot was collected by 

 Captain Pope on the Pacific Railroad Survey at about the same time as Baird and Girard 

 published their work (dated 5 January 1853). It is likely that the real holotype is either USNM 

 2040 or 2041, both of which are indicated in the USNM catalogue to be from Indianola, 

 Texas, and to have been collected by J. D. Graham. Neither of these specimens, however, 

 currently can be located (Steve W. Gotte, in litt). 



Type-locality. — Indianola, Calhoun Co., Texas, USA (but see above). 



Distribution. — Low to moderate elevations (0-610 m) from eastern Kansas, southern 

 Missouri, and extreme southwestern Illinois south to northwestern Louisiana, eastern and 

 southern Texas, USA, and northeastern Coahuila, Mexico. Isolated populations occur in 

 eastern Texas and the Texas Panhandle in the United States. 



Systematic references. — Hardy and Cole (1968).
