Description:Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia The writer tenders his acknowledgements to the officers having immediate charge of these collections, for numerous favors shown him, in a variety of ways, during the prosecution of his researches. Nearly all the known species of the family are represented in the several collections above named; and the libraries of these Institutions contain all needed works of reference. Being based upon such ample data, this monograph ought to embody all that is known of the Alcidae in a technical point of view, and constitute a fair exponent of the same. The writer ventures to indulge the hope that it may not be found to fall far short of this standard. Before proceeding to the proper matter of the subject, it may be well to glance at what has already been done in this family of birds. Following is a list, in chronological order, of the principal works in which Alcidae are made more or less of a specialty, with remarks upon each. It is obviously by no means a bibliography of the family; only those works being noticed in which some special point is presented. It may pass, however, for a reviewing sketch of the literature of the subject, and as such may be valuable and helpful to the student. Consultation of most of the works mentioned below is absolutely necessary to a correct understanding of the subject, except in so far as it may be obviated by perusal of the text of the present paper. I. Review of the Literature of the Family. Certain species of Alcidae made their appearance in the very earliest ornithological writings of which we have any knowledge, long before the establishment of the science upon any fixed and recognized basis. However desirable it may be - as well in justice to early authors, as tending to bring the whole subject in the strongest light - to collate and identify, as far as possible, the older names of these species, the attempt to cite as authoritative names and descriptions which antedate the foundation of the binomial system of nomenclature would be at once embarrassing and profitless. There must be a fixed initial point for the commencement of authority in the matter of names in the existing system of zoological nomenclature; otherwise a writer might adopt names at pure caprice; in which event the species he treats of would be recognizable only by synonymy adduced, or descriptions appended, and names would fail of their proper purpose by becoming simply indices of the extent of his philological research. The date of the tenth edition of the Systema Naturae furnishes an unobjectionable starting-point, beyond which investigation need only extend from motives of curiosity; and is on several accounts more eligible than the date of the twelfth edition. M hring, a mononomial author whose work appeared in 1752, has very frequently been quoted as authoritative, notably, among European authors, by Gray, and among American by Cassin, Baird, Bryant and others, including the present writer. Five genera of Alcidse iXQ instituted in this work of Moehring s: (UChenalopex, based on Alca impennis; (2) Spkeniscus, upon Fraterculaarctica; (3)Arctica, upon Meryulus alle; (4) Vria (sc. Vria), upon U.grylle; and(5) Cataractes upon Lomvia troile. Of these five, Arctica and Cataracies have never come into use, except in an isolated instance or two; Uria is in universal employ, accredited, however, as it should be, to a later writer; AS?Acn cMs is used, in an entirely different acceptation, for a genus of Penguins; and Chenalopex for an Anserine genus. These names, though all positively identified, will not be countenanced in their Mcehringian acceptation, for reasons just mentioned. (1758.) Linnaeus, Syst. Nat., ed. x. - The Linnaean genus Alca at this date comprehended six species, to wit: impennis, torda, "pica," arctica, lomvia, alle. Two Guillemots - qrylle and troile - are presented under the genus Colymbus. ."We have made it easy for you to find a PDF Ebooks without any digging.
