(U.S.N. M. No. 72737; Captain Dallas collector; Dondominguillo, Oaxaca). 



Type.— Brit. Mus. Nat. Hist. No. XXII, 20-a (^(/e Bailey) ; collector 

 unknown. 



Type locality. — Not given by Shaw. Boulenger (Catalogue of the 

 lizards in the British Museum, vol. 2, 1885, p. 196) gives "California," 

 which probably means Baja California. Since the species does not 

 occur there we accept Bailey's restriction to Tampico, Tamaulipas. 



Range. — Atlantic slopes from central Tamaulipas south to the 

 Isthmus of Tehuantepec. Reliably reported only from the states of 

 Tamaulipas, San Luis Potosi (Pujal), Veracruz, and Oaxaca.^^ 



" Burt and Myers (Stanford Univ. Publ., biol. ser., vol. 8, 1942, p. 299) record the species, in error, from 

 Acapulco, Guerrero. 



»» Fitzinger {loc. cit.) attributes this name to Wiegmann, as do also Lichtenstein and Martens (Nomen- 

 clator . . . Berolinensis, 1856, p. 8) ; we are, however, unable to locate Wiegmann's use of the name and 

 attribute it to Fitzinger, as did Bailey, Proc. U. S. Nat. Mus., vol. 73, 1928, p. 10). 



" Reexamination of specimens in the U. S. Nat. Mus. referred by Bailey (loc. cit.) to C. acanthura reveals 

 that two other species were confused with C. acanthura. One specimen from Mirador, Veracruz, is a C. 

 similis; and all from Uruapan, Michoacdn; Tehuantepec, Oaxaca (except Nos. 26341, 58498); Isabel Island; 

 Tres Marias Islands; Cuicatlfin, Oaxaca; Tlapa and Balsas, Guerrero, are C. pectinata. That all other west- 

 coast specimens in his list, from other museums, are also C. pectinata we believe is virtually a certainty.
