428 The History of Ichthyology 



tionships of the Ostracophores as well as Palaospondylus and 

 the Arthrodires may be named Traquair, Huxley, New- 

 berry, Smith-Woodward, Rohon, Eastman, and Dean; most 

 recently William Patten. Upon the phylogeny of the sharks 

 Traquair, A. Fritsch, Hasse, Cope, Brongniart, Jaekel, Reis, 

 Eastman, and Dean. On Chima^roid morphology mention 

 may be made of the papers of A. S. Woodward, Reis, Jaekel, 

 Eastman, C. D. Walcott, and Dean. As to Dipnoan relation- 

 ships the paper of Louis DoUo is easily of the first value; of 

 especial interest, too, is the work of Eastman as to the early 

 derivation of the Dipnoan dentition. In this regard a paper 

 of Rohon is noteworthy, as is also that of Richard Semon on 

 the development of the dentition of recent Neoceratodus, since 

 it contains a number of references to extinct types. Interest 

 notes on Dipnoan fin characters have been given by Traquair. 

 In the morphology of Ganoids, the work of Traquair and A. S. 

 Woodward takes easily the foremost rank. Other important 

 works are those of Huxley, Cope, A. Fritsch, and Oliver P. 

 Hay. 



Anatomists. — Still more difficult of enumeration is the long 

 list of those who have studied the anatomy of fishes usually 

 in connection with the comparative anatomy or development 

 of other animals. Pre-eminent among these are Karl Ernst 

 von Baer, Cuvier, Geffroy, St. Hilaire, Louis Agassiz, Johannes 

 Mtiller, Carl Vogt, Carl Gegenbaur, William Kitchener Parker, 

 Francis M. Balfour, Thomas Henry Huxley, Meckel, H. Rathke, 

 Richard Owen, Kowalevsky, H. Stannius, Joseph Hyrtl, Gill, 

 Boulenger, and Bashford Dean. Other names of high authority 

 are those of Wilhelm His, Kolliker, Bakker, Rosenthal, Gottsche, 

 Miklucho-Macleay, Weber, Hasse, Retzius, Owsjannikow, H. 

 Miiller, Stieda, Marcusen, J. A. Ryder, E. A. Andrews, T. H. 

 Morgan, G. B. Grassi, R. Semon, Howard Ayers, R. R, AA'right, 

 J. P. McMurrich, C. O. Whitman, A. C. Eyclesheimer, E. Pahis, 

 Jacob Reighard, and J. B. Johnston. 



Besides all this, there has risen, especially in the United 

 States, Great Britain, Nonvay, and Canada and Australia, a 

 vast literature oi commercial fisheries, fish culture, and anglino-, 

 the chief workers in which fields we may not here enumerate 

 even bv name.
