Review excerpt:
"In essence, the book is now a series of illustrated keys for identification. each key being preceded by supplementary information essential to its use. These keys, with a few exceptions. are easily followed by the nonspecialist and in most instances may lead the student to a generic identification, although frequently specific determinations can be made."
