250 ORDER ACANTHOPTERYGII. 



Others are covered with scales, and have no ap- 

 pendage over the eye \ 



We might distinguish those in which the scales and 

 cirri are wanting, but which have lines of pores pierced 

 in the skin, and hooked teeth in the lower jaw 2 . 



The fourteenth family of the Acanthopterygii, or 

 that of 



Labroides, 



Is easily recognized by its aspect. The body is ob- 

 long and scaly ; a single dorsal is supported in front 

 by spines, each of which is generally furnished with a 

 membranous appendage ; the jaws are covered with 

 fleshy lips ; there are three pharyngeals, two upper 

 ones attached to the cranium, and a large lower one, 

 all three armed with teeth, now en pave, then in 

 points or laminae, but generally stronger than 

 usual ; an intestinal canal either without cceca, or 

 with two very small ones, and a strong natatory 

 bladder.
