324 CLASSIFICATION OF FISHES. 



united to the second dorsal and to the anal, both of 

 which are very long. In all other respects, however, 

 the species of this genus differ so very much from the 

 general structure of the Gadidte, that we cannot think 

 they are naturally located with them. They may, 

 indeed, constitute the most aberrant type, or that which 

 we have assigned to Brosmius ; but our impression is, 

 that Macrourus represents the anguilliform or apodal 

 division of the Triglidce, in which group we have there- 

 fore placed it. 



(272.) Without going into an extended exposition of 

 the analogies of this family, it will be sufficient to call 

 the naturalist's attention to those general points of re- 

 semblance to the higher types or divisions, which are 

 presented by what appear to be the leading genera of the 

 Gadidte. Thus we have the prevalent character of 

 the cartilaginous order indicated in the very broad and 

 depressed muzzle of Phycis and Raniceps; while that of 

 the apodal is clearly symbolised in the eel-like form of 

 Brotula and Pteridium, where the caudal fin is con- 

 founded, as it were, with the dorsal and the anal. Fur- 

 ther, if we confine our attention to the five sub-genera, 

 here indicated, of the genus Gadus, it is not difficult to 

 trace a resemblance to the higher divisions of the whole. 

 This will be best seen in the following table, with which 

 we may conclude our sketch of this family.
