274 PISHES. 



toral and ventral fins : the vertical fins (that is the dorsal), the 

 anal and caudal must be considered as part of the trunk. 



The head, with a greater number of moveable parts than is found 

 in the Mammalia, requires to be subdivided into a great many 

 regions. We distinguish in it, the cranium, the jaws, the bones 

 situated beneath the cranium and behind the jaws, and which serve 

 to suspend them and give them power of motion, the bones of the 

 opercula, or the sort of lids which open and close the aperture of the 

 gills ; the bones which are nearly external that surround the nostril, 

 the eye, or the temple, or which cover a portion of the cheek. 



The respiratory apparatus contains the os hyoides and its appen- 

 dages, or in other words, the branchiostegal rays, and the ai'ches 

 which support the gills, with the ditferent pieces borne by these ar- 

 ches, or which are suspended in them ; the whole of these in combina- 

 tion perform the functions of both larynx and trachea ; lastly, it 



are expressly devoted to the head of Fishes. It will not be necessary for us to make 

 use of the figures of these authors in our descriptions, as we have all the skeletons 

 which they have communicated, and a great many others which now have accumu- 

 lated to nearly a thousand.
