ment is now present on the dorsal and 

 caudal fins. The upper jaw is noticeably 

 longer than the mandible. The teeth are 

 well developed. The spines on the snout, 

 head, and body have become larger and 

 are more numerous. All the fins have 

 well-developed rays. The eyeball is still 

 invaginated. 

 32.5 mm — The dorsal barring has become much 

 more pronounced and appears to consist 

 of four or five "double bars". Pigment is 

 much darker in the dorsal and caudal fins 



and has extended into the anal fin. 

 Spines have developed on the ventral 

 surface of the snout and have become 

 much more pronounced on the body. 

 The two long preopercular spines have 

 become greatly reduced. The eyeball is 

 no longer invaginated. 

 62.5 mm — The pigment is more definite in both the 

 "double bars" and in all the fins except 

 the pectorals, which still lack pigment. 

 Both jaws, the head, and the body are 

 covered with regular rows of fine spines.
