closed. The air-bladder may be lost. An eye-muscle canal is present, 

 and the parietals may meet above the supraoccipital (p. 347). The dorsal 



spines are often provided with 

 poison-glands.

Family Triglidae. The head 

 is completely covered by a cuirass, 

 formed partly by the suborbitals 

 (Fig. 470). The anal fin is spine- 

 less, the dorsal fin becomes sub- 

 divided, and the pelvic fins are 

 widely separated. Two or three 

 of the ventral (anterior) dermal 

 pectoral rays become specialised 

 as independent feelers capable of 

 separate movement (Hamburger 

 [195]). The pectoral fin is 

 generally large and brilliantly 

 coloured. The post-temporal is 

 fused to the skull, and the myodome is present. The body is covered 

 with rough scales, or sometimes with an armour of bony plates (Peristedion) 

 (Fig. 472).
