The range maps are so general as to be mostly useless. They're incredibly small, to the point where it's hard to discern where the lines on it are; is that snake's western range limit NM or AZ? You can't tell! The written descriptions of ranges are too vauge as well; they list eastern, western, southern and northern limits, but it's not like an animals range will make a nice little square; there are places within those boundaries where it does not occur. Maybe a lizards westernmost point is in, say Alamogordo, NM: it'll list that as it's westernmost point. but say, as it's range extends northward, it is restricted to a more easterly distribution; that won't be mentioned.

Furthermore, the guide is 25 years old. There have been massive taxonomic revisions since this was written; new species have been discovered, some species have been combined, some subspecies complexes split, etc. Ranges have also shifted since '79, due to development and climatic changes.

Also, the guide only deals with species level info. This is unnacceptable for some animals; L. getula (kingsnake) has some 7-8 subspecies, ranging from the mexican black to the desert to the eastern; these animals have markedly different apperances, habitat, ranges, and behaviors. But the guide doesn't deal with that; it list info for "L. getula" in general, without dividing it into subspecies information. This makes the guide worthless for Pituophis melanoleucus, Lampropeltis getula, Lampropeltis traingulum, and several other species which contain a wide range of different subspecies.

So what to do? Buy a good local field guide; they exist for most states- Degenhardt's Amphibians and Reptiles of New Mexico is execellent. Texas Snakes (Dixon) is good. Failing all else, most states maintain a listing of most native fauna online, usually whatever department deals with hunting and state parks will have a link to it. There is probably a good field guide for reptiles and amphibians of your state. If you need one for a bigger area, try Peterson's. They offer regional guides; one western and one eastern and central. They're a little more difficult to learn to use, but they're far more current, far more detailed, and once figured out, far more useful.


A comprehensive, well organized field guide.   June 22, 1998

The photos which illustrate this book are organized in such a way that one does not have to be familiar with reptiles and amphibians to make resonably accurate field identifications. For instance, the photographs of striped snakes are grouped together so that you can easily check for that matches the animal you have found.

The text and range map section gives much valuable information as to habitat and behavior as well as breeding and the size of neonates as well as adults.


Excellent field guide! Mostly USA species, light on Canadian   November 10, 1999

An excellent field guide (particularly in plastic cover-softback). Covers many USA species, but very light on Canadian species. Better than many I've seen though. Excellent color plates for accurate identification of species.
