BULLETIN OF THE BUREAU OF FISHERIES 
Pigmentation has progressed rapidly, though it is not complete. Individual 
chromatophores are present everywhere and are concentrated in definite areas to 
form bars which are not developed equally early in all specimens. Usually, however, 
they are more or less definite in specimens 10 mm long, quite distinct in 12-mm fish, 
and generally 7 in number, as in the adult (fig. 20). 
Specimens 15 to 18 mm long .-—' The body has become somewhat deeper, the depth 
now being contained about 2.9 in the length to base of caudal. The head remains 
short and deep, about 3.0 in length. The snout is a little less blunt and slightly 
longer, about 4.1 in head; eye longer than snout, about 3.0 in head. The mouth 
remains small, slightly oblique, the gape anteriorly being nearly on the level with the 
lower margin of the eye; maxillary reaching slightly past anterior margin of eye. 
Preopercular spines, present in smaller fish, no longer are evident. The lateral line 
generally is rather fully developed in specimens 18 mm long, and the body is covered 
with scales. The dorsal spines have increased in proportionate length, but remain 
notably shorter than the soft rays. The anal spines are well developed, the second 
one already being the strongest as in the adult. The outer unbranched ray of the 
ventral is not yet fully developed as a spine; the second ray with a free filament 
distally, frequently reaching origin of anal. 
Specimens 18 mm long, in the fresh state, have the general color of the adult, 
including the characteristic black cross bars (fig. 21).
