Excerpt from Contributions to the Natural History of the Fresh Water Fishes of North America, Vol. 3 I have selected the Artedian genus Cottus as the subject of my first monograph, on account of the interest which attaches to the questions involved in its investigation. The first of these questions is to ascertain whether there really exists but one single species of the genus in Europe, and another in America. The second, whether indeed the same species is common to both countries, as was at one time supposed. My investigations embrace, and, I hope, solve both of these questions. The materials made use of are numerous and of special value, some of them absolutely essential to the proper determination of the above-mentioned points. As far as it has been in my power, I have consulted the original documents, and their authors themselves. Thus I owe to Professor S. S. Haldeman an authentic individual of his C. viscosus. Through the kindness of Professor James Hall, of Albany, I have studied the specimen drawn and described by Hr. De Kay under the name of Uranidea quiescens, which proved to be a true Cottus. Mr. W. 0. Ayres has placed in my hands specimens of his C. gobio from the State of Connecticut. From information communicated by Dr. J. P. Kirtland, of Cleveland (Ohio), I have identified his C.gobio. Rev. Z. Thompson, of Burlington (Vt.), has sent me a species Hitherto undescribed. Specimens caught near the White Mountains were communicated by Dr. D. Humphreys Storer. I have made a complete study of the species brought by Prof. Agassiz from Lake Superior. In examining the collection of fishes in the Academy of Natural Sciences of Philadelphia, with the assistance of Dr. J. Leidy, I found one specimen by which I became fully satisfied of the existence of two species in the tributaries of the Ohio River. Rut the most important contributions have been from the collection of Professor .S. F. Baird, now at the Smithsonian Institution. Numerous specimens of C. viscosus and others have enabled me to give the anatomical details contained in Chapter II. I beg all these gentlemen to accept the assurance of my deepest gratitude, and to receive my labor with the same indulgence which they have shown towards me during its elaboration. Most of my descriptions rest upon the examination of numerous specimens: a few of them are drawn from one individual, but the species will appear distinct enough to be justified.
