The plan of this work was quite elaborate, and systematic summaries of the an- 

 atomical characteristics of the various major groups have been given in the volume 

 published, in addition to an extended introduction on Ichthyology. 618 nominal 

 species are described or indicated, including those which the author did not especially 

 call doubtful, but which, from want of sufficient precision and details in the descrip- 

 tions or other cause, he could not contrast in his synoptical tables : these 616 species 

 were arranged under 101 genera, 35 families, and 7 orders, and represented 4 subclasses. 



In order to exhibit the contrast in the mode of treatment of the groups in question 

 by two contemporaneous ichthyologists, the following details respecting the numbers 

 of species are given without other comment than that the sequence and details of 

 classification in Giinther's work are also different. 



I e . Sous-classe, Elasmobranches 

 Plagiostomes 

 Squales 

 Raies 



Holocephales 

 H e . Sous-classe, Ganoides. 



Chondrostes 

 Holostes 



Lepidosteides 



Polypterides 



Amiades 



IIP. Sous-classe, Dipnes 

 IV e . Sous-classe, Lophobranches

 only assumed with the fourth volume : at the end of that volume, general titles for 

 the preceding ones were supplied, and that and all subsequent ones had double titles, 

 the general and the special here reproduced, viz :
