Memoirs of the Museum of Comparative Zo Logy, at Harvard College, Vol. 43
Excerpt from Memoirs of the Museum of Comparative Zo logy, at Harvard College, Vol. 43 The revision of the American Characidae, based on the collections of the Nathaniel Thayer Brazilian Expedition in the Museum of Comparative Zoology was commenced by Mrs. Rosa Smith Eigenmann and myself in 1888. A little more than a year later the work was temporarily suspended. The published results, so far as obtained, are enumerated on p. 8-10. Work was resumed in 1903 with the collections of Indiana University and of the United States National Museum, and a monograph completed in 1906. Types in several museums in London, Paris, and Vienna were examined in 1906 and 1907. In 1907 the study of the collections made by the Thayer Expedition was renewed. This material made it necessary to rewrite the entire monograph, for, forty years after it was gathered, it was still the most important collection of South American fresh-water fishes, and contained a large number of undescribed species and genera. The revised monograph, through the Tetragonopterinae, was finished in the spring of 1908. During the preparation of this revision it became apparent that the material at my command, from several regions of South America, was deficient. To obtain material from one of these regions, I spent the autumn of 1908 in British Guiana. Volume 5 of the Memoirs of the Carnegie Museum contains a detailed account of this Guiana Expedition. In May, 1909, my position of Curator of Ichthyology in the Carnegie Museum placed me in charge of another large series of South American fresh-water fishes. This collection was made under my general direction, between November 6, 1907 and January 10, 1910, by Mr. John D. Haseman, one of my former students. For the most part it came from areas not covered by the Thayer Expedition. The Director of the Carnegie Museum, Dr. W. J. Holland, has kindly allowed me to incorporate in the present monograph the results obtained from a study of the Carnegie collections.
