The "Catalogue of Neotropical Squamata" has proved a most useful 
contribution to zoologists working in Central and South America. 
As with all taxonomic lists and keys, new studies of the fauna soon 
make the contents outdated. The reprinting of this catalogue 
offers an opportunity to add the new species and taxonomic 
arrangements described since the original publication, to correct 
errors, and to comment on the accuracy of the keys. 
The following corrections, additions, and comments concerning the 
South American fauna derive principally from P.E. Vanzolini; 
however, other corrections and additions have been taken from the 
notes of John E. Cadle and Ronald I. Crombie. The following lists 
include only those genera in which we are aware of recent (1969-84) 
taxonomic changes. For the sake of brevity, literature citations to 
the older (<1970) name are generally not included unless a 
correction is presented; readers are advised to use the Catalogue 
indices to locate the name and the citation (G. Zug, ed.)
