The Brachyura of the Challenger were described by Mr. E. J. Miers, the Anomura by Dr. J. R. Henderson, the Macrura by the late Mr. C. Spence Bate, the Cumacea by Professor G. O. Sars, the Isopoda by Mr. F. E. Beddard. The other pictorial authorities are Gesner's Historia Animalium,' Herbst's 'Naturgeschichte der Krabben und Krebse,' Desmarest's 'Considérations générales sur la classe des Crustacés,' de Haan's • Crustacea' in von Siebold's' Fauna Japonica,' and various papers of modern date by G. O. Sars, S. I. Smith, C. W. S. Aurivillius, H. J. Hansen, C. Bovallius, C. Chilton, MM. Giard and Bonnier, R. Kossmann, W. A. Haswell, and Victor von Ebner. For the text, as distinct from the illustrations, many other authorities would have to be named, but the text will speak for itself. As to the reproduction, on a scale suitable to these pages, of figures so numerous and so diversified from originals neither equal in merit nor uniform in style, I am indebted to Mr. James D. Cooper for the care and skill exhibited in carrying out a task of no mean difficulty. |
