Transcriber's Notes.

This file was derived from scanned images. With the exception of the list of typographical errors that were corrected below, the original text is presented.

In the original, the Plates were grouped together between pages 328 and 329. Here the Illustration: block which contains the text associated with the Plates were moved just above the text in their respective Systematic Account listing. The Plate text contain the notation "x 2" after the caption to let the reader know that the image was enlarged by a factor of two.

Typographical Errors Corrected:

Several minor typographical corrections were made (missing periods, commas, misspelling of 'and', etc.); but are not indicated here. More substantial changes are listed below:
