The first edition of this authoritative compilation, published in 1978, listed 454 species of
amphibians, turtles, reptiles, and crocodilians, and was quickly adopted nationwide as a
source for common names for these North American (north of Mexico) animals, names
that could be consistently used worldwide to avoid confusion, both in spelling and during
conversation.

This sixth edition, published in printed form on 5 April 2009, lists 621 species of
amphibians, turtles, reptiles, and crocodilians in the United States and Canada, an increase
of 167 species (27%) since 1978 and an increase of 232 species (37%) since 1956, which
demonstrates clearly how much the diversity of these animals in North America was
previously underestimated.

The standard common names in the fourth edition (1997) of this list were used exclusively
in the well-known "Peterson Field Guide to Reptiles and Amphibians of Eastern and
Central North America" (third edition expanded, 1998, Houghton Mifflin Co., Boston),
were adopted exclusively in the "The Frogs and Toads of North America" (recently
published by Houghton Mifflin; Elliott et al. 2009) and will be adopted for the forthcoming
fourth edition of the Peterson Field Guide, which has the widest distribution of any book
ever written about these creatures.

The pdf version of this sixth edition has been updated since the print version was issued
on 5 April 2009 (thus far, over 1,525 copies of this latest edition have been requested
and/or mailed worldwide); a few errors of author attribution and date (ordinal and familial
only), as well as a single typo (fortunately, not of a scientific or common name), have been
corrected. Should anyone note any other errors, we would much appreciate being notified.
We will promptly correct the pdf version and re-install it in the CNAH PDF Library as often
as corrections warrant. We anticipate that the next (seventh) edition of this list will be
published in 2014.

The CNAH web site, which is the largest academic herpetological web site in the world,
has adopted the common and scientific names of this sixth edition. The CNAH web site
has had over 840,000 visitors since it was launched on 1 January 1998, and recorded over
1,000,000 hits in calendar 2009 alone.
