74 CLASSIFICATION OF FISHES.

We have merely inserted the column of the orders 

 of fish to illustrate the analogy of Myxodes, the only 

 genus in the whole tribe which imitates the sharks in 

 having the head elongated in front, the muzzle pro- 

 jecting, and the mouth placed beneath. Having de- 

 tailed all the characteristics of these genera in our 

 systematic arrangement, we shall only at present take 

 a rapid glance at their analogies, leaving the reader to 

 extend them, if he so pleases, to other groups, 



(79-) Let us now turn to the sub-famUy, Clininje. 

 These blennies, as already noted, are distinguished, in 

 the first instance, by the spiny rays of their dorsal fin 

 being always more numerous than those which are soft; 

 whereas, in the last group, this proportion was exactly 

 reversed. In the next place, their teeth are generally 

 of two sorts, so as to unite, as it were, the strong teeth 

 of Blennius with the more slender ones of Salarias, here- 

 after mentioned. This character, however, does not 

 pervade the whole group ; and jet, by attending to its 

 modification, we shall find that the difference wUl lead
