ANALOGIES OF THE SALMONIDiE.

the reader subsequently compares the circle of the ScU- 

 monidcB with that of the tribe Macroleptes, he will find 

 that Sudis stands opposite to Anabas and the other laby- 

 rinthiform fishes^ as their representative among the soft- 

 rayed families, or the Malacopteryges. This analogy 

 may, nevertheless, truly exist, and yet the precise situation 

 of Sudis may be in some other circle ; although, for the 

 present, we believe it is really where we have placed it. 

 (230.) Such are what we consider as the three great 

 aberrant divisions of the whole sub-family of the Salmo- 

 nincej and we are now to see if they tally with those two 

 whose types we have more particularly investigated, 

 namely, the Salmonincs and the Charao'mce,

(231.) Lastly, as it will tend much to strengthen our 

 disposition of the SalmonidcE, we shall compare the five 

 groups in which we have arranged them with the five 

 principal divisions of the whole family ; because, if the 

 series in these are natural, they must possess some points 

 of mutual resemblance.
