PLECTOGNATHI. 
The maxillary bone soldered or fixedly attached on the side of the intermax- 
illary, which alone forms the jaw, and to which the palatine arch is dovetailed 
by a suture within the cranium, and consequently has no power of motion. 
Opercula and the rays are concealed under a thick skin, which only permits 
a small branchial cleft to be visible externally. 
FAMILY XXIX. GYMNODONTIDE. 
Instead of apparent teeth, the jaws are furnished with an ivory substance,
