Wiegmann (1833) described Bufo valliceps based on a series of specimens received from Ferdinand Deppe and Wilhelm Schiede. Wiegmann did not indicate upon how many specimens of B. valliceps this description was based, nor did he give any locality data for the series other than stating in the introduction that Deppe's and Schiede's material was from Mexico. Kellogg (1932) examined the type series of B. valliceps and noted that there were five syntypes catalogued as ZMB 3525-27, 3532 (ZMB 3525 was given to two of the syntypes). Kellogg (1932:69-70) stated that the locality data for four of the five syntypes is "Mexico" and that the fifth syntype (ZMB 3532) bears the locality data "Vera Cruz, Mexico." Apparently based on this information, Smith and Taylor (1950) restricted the type locality of B. valliceps to "Veracruz, Veracruz, Mexico." Schmidt (1953) also restricted the type locality of B. valliceps to "Vera Cruz, Vera Cruz." Only the latter type locality restriction is mentioned in the account of B. valliceps in Frost (1985). As Dunn and Stuart (1951:678) pointed out, these kinds of type locality restrictions are "... without legal status ...." Mendelson (1994:14) compounded the problem by stating "The type locality of B. valliceps is near the city of Veracruz, Veracruz, Mexico (Frost, 1985)." Mendelson (1998) studied the geographic variation in the wide ranging B. valliceps (southern M ssissippi, United States of Americ , to extreme northeastern Costa Rica) and oted (p. 11) that "... northern B. valliceps are la ger and have a distinctive pattern and skin texture compared to B. valliceps from Central America; these differences perhaps warrant recognition of B. nebulifer [for the northern population]." Mendelson, however, chose not to "... propose recognition of B. nebulifer at this time." Specimens from low elevations of e southern portion of the Mexican state of Veracruz were included in Mendelson's Cen-
