THE CENTRISCIN^ AND ECHENEID^.

shows that it has nothing more in common with Fistu~ 

 laria than it has with Gomphosis, Mormyrus, and other 

 long-snouted types ; all of which are only represent- 

 ations, in fact_, of the SyngnathidcB : the hard scales of 

 one type (C. scolopax, fig. Q. a) show its analogy to the 



gurnards and to Capros, while the plates on the other, 

 Amphisile scutatus Kl. (^Jig. 6. b), are exactly analogous 

 to those of the loricated Siluridce. 



(44.) The EcHENEiD^, or remora-fish, we place at 

 the end of this tribe, as representatives of the Cyclop- 

 teridce, or suckers, without any fear of violating the 

 order of nature. In all but their singular apparatus for 

 adhesion, they exhibit the unequivocal characters of this 

 tribe, particularly in their hard and almost cartilaginous 

 pectoral and caudal fins : in the structure of the mouth, 

 and some other curious particulars, they evince a rela- 

 tionship to Sphrycena; but, like the last group, they 

 stand more isolated, in this and in all other systems, 

 than any of the existing forms in the entire class. 



(45.) We shall now assemble, and exhibit in one view, 

 the chief groups in each of the five great divisions of the 

 tribe to which this chapter has been devoted ; and then, 

 — having already said sufficient to enable the philosophic 

 ichthyologist to apply our remarks to each and all, — we 

 must leave their further exposition to those who may 

 derive pleasure in following out our theory.
