GENERAL* 
A. S. Woodward, in the Introduction to the second volume of his 
Catalogue of Fossil Fishes (m/rd, p. 7), discusses the principal schemes 
of classifications hitherto propounded, and adopts a division of the 
Fishes (exclusive of the Cyclostomata and Acrania) into 5 subclasses, 
viz., Elasmobranchii, Holocephali, Ostracodermi, Dipnoi, and 
Teleostomi. This arrangement is followed in the present report. 
E. Koken, Z. geol. Ges. xliii, p. 154, has considerations on the bearing 
of the study of Otoliths to the natural classification of Fishes. From au 
assumed original type of organ of hearing the author derives three inde- 
pendent lines of evolution: 1. Holocephali , of which the Dipnoi area 
further modification ; 2. Elasmobranchii ; 3. Ganoidei and Teleostei. The 
study of this organ does not support the view that the Clupeoids are 
derived from the group of which Amia is the living representative. The 
classification of the Teleostei into Physostomi , Acanthopterygii , &c., is 
criticized at some length, and found to be on the whole most artificial.
