This checklist of colubrid generic names, based on the above morphologic indicators, is divided into five tables. Dentition, being more completely documented than the pres-ence of Duvernoy’s gland, forms the basis for Tables 1-4 as follows: Tables 1 and 2, opis-thoglyphous genera, New and Old World; Tables 3 and 4, aglyphous genera showing marked enlargement of the rear maxillary teeth, New and Old World. References for accepted generic names and dentition as well as notations of Duvernoy’s gland presence and geographic distribution are included.  Table 5 lists the aglyphous genera of the world, with unmodified rear maxillary teeth, examined by Taub (1967) for Duvernoy’s and supralabial glands. References for dentition and geographic distribution are included.  Listing of a given genus indicates that one or more species of the genus has the character-istic in question. Dual listing indicates that the dentition type varies among the species of the genus or that authorities differ as to their description of the dentition type. In some cases a generic name was traced from an earlier synonym.
