of lizard classification (the basic phylogenetic position of the genera con- 

 cerned is presented on p. 3), For each taxon I have presented a very brief 

 synonymy, beginning with a citation to the original description of that 

 taxon and its type locality, plus the holotype and its location in paren- 

 theses. Similar citations and information are included for all taxa 

 described from Ecuador that have been synonymized with other species. 

 I have attempted to include all erroneous records in the literature based 

 upon Ecuadorian specimens, listing them within the synonymy of the species 

 to which they properly belong under the name used by the author, and 

 separated from the citation by a period and dash. Obviously, this is im- 

 possible where the specimens have not yet been reexamined, either by 

 myself or by someone discussing them in print, and without question some 

 erroneous identifications have served as the basis for inclusion of some taxa 

 within this list. 



An asterisk following either a generic or specific name indicates that that 

 taxon has not yet been collected in Ecuador. In all cases there is reason 

 to anticipate the occurrence of these taxa in Ecuador, but it should never 

 be assumed that all likely members of the fauna have been anticipated. 

 The failings attendant upon all keys exist here as well. Keys must be 

 written on the basis of the known or expected variation, and it is im- 

 possible to include all of the individual divergencies from type of which the 

 genome is capable. Merely to reach a name does not put the final stamp 

 of adequate identification on the specimen, but only provides the basis for 

 a thorough check against the available descriptions and comparative 

 material. Two species may share all of the characters utilized in the 

 dichotomies and still be strikingly different from one another.
