This work is a continuation of the author's report on the Cirripedia contained in the United States National Museum, of which the portion relating to pedunculate forms was published in 1907. It was at first intended to record the species of sessile Cirripedia in the Museum, with their localities, and to describe and figure new forms. As the collection was worked over, its wealth in American barnacles became apparent and contains nealy every known species of the Western Hemisphere, many of which show variations special to American waters, altering the scope of this work which may now be described as a monograph of American sessile barnacles.

Excerpt from The Sessile Barnacles (Cirripedia) Contained in the Collections of the U. S. National Museum: Including a Monograph of the American Species By the copious illustration of American forms, by large-scale draw ings and photographs, their identification should be easier. Until one has studied barnacles deeply enough to have standards of com parison, even the inimitable descriptions of Darwin are difficult to follow, especially if one is dealing with forms differing somewhat from those described. The appeal to the eye will often relieve the student from uncertainty. Identifying by the pictures may be a primi tive and superficial method, yet such short cuts are permissible in case one merely needs the name of an animal which has been taken as the subject of embryological, ecological, or other non-systematic studies. The student must be warned, however, that many species have parallel mutations, vary in the same way under similar condi tions, so that external form by itself is rarely a reliable criterion. The opercular valves, the details of structure of the plates of the wall, and the structure of the feet are the important characters.
