FOOTNOTES:
[1] The Chilopoda and Diplopoda are sometimes regarded as forming a single class—Myriopoda.
[2] The account given here of the structure of the Lobster applies almost equally well to the River Crayfish or the Norway Lobster. The student is recommended to follow the description with a specimen of one of these animals before him.
[3] I am indebted to Mr. J. T. Cunningham for calling my attention to some of the facts here recorded.
[Transcriber's note:]
In general every effort has been made to replicate the original text as faithfully as possible, including some instances of non-standard spelling and punctuation. Certain animal names (notably, "Lobster", "Crab") have occasionally been changed from lowercase to capitalized when the pattern of capitalization used by the author has permitted the transcriber to judge that the omission of such capitalization was likely to be typographical in nature and not intentional. The hyphenation is occasionally variable; this has not been altered. A few obvious punctuation errors have been corrected, as well as the following apparently typographical errors:

p. xiv (List of Illus.) Plate II page reference, changed from 63 to [36]

Some illustrations have been moved from their original locations to paragraph breaks, so as to be nearer to their corresponding text, and for ease of document navigation. Missing page numbers correspond to pages not numbered in the original document. References to scale in illustration captions are those of the original publication, and therefore do not correspond to the scale of the images in the HTML version of this ebook.
