The systematic arrangement of Cuvier wasextended and modified by Louis Agassiz to in-clude the multitude of fossil forms made knownin his Poissons Fossiles. Still more impor-tant corrections and changes in the generalscheme of classification were suggested by Jo-hannes Midler, the greatest comparative anat-omist of the 19th century. Other valuablecontributions to taxonomy have been made byDr. Giinther, Dr. Edward Drinker Cope, andespecially by Dr. Theodore Gill, a critical writerwho ranks with the first of taxonomists of theage, and whose views have been accepted insubstance if not in name as representing ourbest present knowledge of the origin and rela-tionship of forms among the vertebrate Black-banded Rock-fish (Sebastodts nigricinctus). recorded by Artedi — a small portion of the12,000 species now actually known (1903). But the work of Artedi is masterly in itsmethod and shows a stronger touch than that ofany of his successors in ichthyology until thetime of Cuvier. In the Systema Naturae Lin-na;us did little more for fishes than to substitutebinomial names for the descriptive phrases ofArtedi. With the Regne Animal (1817-28) ofCuvier, a new era in zoology began. In thisepoch-making work the Animal kingdom, asthe title indicates, was arranged according toits organization. Comparative structure foundsits reflection in the schemes of application of the principles of morphologywas carried out in detail with the fishes in thegreat Histoire Naturelle des Poissons (1828-49) of Georges Dagobert Cuvier
