In regard to the analogy between Huro and Mullus, it 

 can only be rendered equally clear with the others by 

 looking to the other types, of which both are diversified 

 representatives : thus, if we compared the above se- 

 ries of genera with the orders of fishes, Huro would 

 come in precisely opposite the Plectognathes, wherein 

 we have the frog-fish, whose mouth is formed on the 

 same general plan. The whole of the other analogies 

 are so clear, and they follow each other so harmoni- 

 ously, that we need not enter into any further explana 

 tion of them. 



(17.) Such are the principles upon which we have 

 analysed and arranged nearly the whole of the immense 

 tribe of the Acanthopteryges, or spiny-finned fishes ; and 

 were we not straitened for space, we should be able to 

 lay before the reader similar results to those we have just 

 detailed, in almost every group, down to the succession 

 of the sub-genera. Every professed ichthyologist, in- 

 deed, will be able to do this himself; for as the differ- 

 ent groups and types are aU placed in our systematic 

 arrangement in conformity with these principles, so, 

 upon comparing their contents, and studying the prin- 

 ciple of variation, he will be at no loss to discover all 

 the analogical resemblances we have just seen, as ex- 

 hibited in the typical perches : they are, in fact, but a 

 repetition of the very same types differently modified : 

 our notices, therefore, of the remaining groups of this 

 tribe must be more than usually brief. 



(18.) The SerraninaB is the second, or sub-typical, 

 division of the Percidce; even more numerous in species, 

 and far more beautiful in their colours. They are all 

 marine, abounding in the seas of warm latitudes, but 

 very rarely straying so far north as Britain : only one
