Masticophis flagellum Uneatulus Smith 



Since the description of M. f. Uneatulus (Smith, 1941), in which the 

 specimen from Lagmia, Valencia Comity, was indicated as a paratype, 

 only one additional individual, to my knowledge, has been collected 

 in the Zuni region. It comes from the Plains Life Belt at 6300 feet, 

 where narrow-leaved yucca and one-seed junipers are prevalent. This 

 coachwhip snake may reach the approximate northwestern limit of 

 its New Mexico range at the eastern end of the Zunis. It is presently 

 unknown in McKjnley and San Juan Counties, although Maslin 

 (1959, p. 57) saw what he presumed to be AI. flagellum in adjoining 

 Montezuma Count}", Colorado. 



The recent specimen, an adult male, 1070 mm. in total length, 

 has longitudinal dark lines on the dorsal scales but retains dark 

 anterior cross bands and lacks the diagnostic red subcaudal color. 

 Its subspecific allocation is, therefore, tentative. I must agree with 

 Wright and Wright (1957, pp. 437-438), who remarked on the difficult 

 southwestern members of the M. flagellum complex and considered 

 Smith's contribution (1941, pp. 394-397) as tentative.

Masticophis taeniatus taen ia tus Hallowell 



Smith and Taylor (1950b, p. 359) apparently overlooked historical 

 circumstances in restricting the type locality of this whipsnake to 

 Shiprock, San Juan County, New Mexico. The actual type locahty 

 cannot be determined exactly, but it can be clarified by the following 

 facts. S. W. Woodhouse, accompanying the 1851 Sitgreaves Expe- 

 dition, collected the form described by Hallowell (1852, p. 181) as 

 Leptophis taenita [sic] and later stated by him (Hallowell, 1854, p. 134) 

 to have come from "New Mexico, west of the Rio Grande." Wood- 

 house came no closer than 100 miles of Shiprock in his journey from 

 Albuquerque to the Zuni Pueblo, but he could have taken M. t. 

 taeniatus anywhere in the Rio Grande basin between El Paso and 

 Zuni (Hallowell, 1854, p. 147). Apparently he did not collect snakes 

 west of Zuni, for he was incapacitated partially by a bite from Crotalus 

 viridis in that locality.
