Transcriber's Notes For consistancy, a number of word which had alternate spellings were altered to match the most prevalent version used. For example, where the word Mexico was used in the body of the article, the more frequent spelling (México) was substituted. However, in the reference sections, the spelling was not altered as that may have been the spelling used by the article's author. All occurrances of Érpétologie Genérale were correcteded to Erpétologie Générale (Pp. 255, 262, 267, 277, and 278). On page 279 under _Variation_ there appears to be a miscalculation: 668 mm. + 182 mm. = 850 mm. not 840 as in original text.
