"The Key" is unique: it is a long dichotomous key that goes on and onfor 513 pages of small type. The area it covers is that of "Gray'sManual" (1950). Nomenclature is of that work, too, but supplemented, when needed, by "more modern" names. Two sections make up most of thebook. The first (pages 1-82) is a key to families. The second (pages83-513) has keys to genera of the families and to species of genera.Used throughout is alphbetical arrangement; the familial and genericnames appearing, intermixed, in dictionary-like order. Common namesequated to scientific names appear, too, alphabetically.
