Family LUTIANID. 
123. Hoplopagrus guntheri Gill. PARrcGo Coconaco. 
This beautitul and most interesting species is very com- 
mon about Mazatlan in deep water among the islands. It 
reaches a considerable size, the largest specimen seen by 
us having a length of 26 inches. There is considerable 
difference between the young and the old in coloration, 
the bands so conspicuous disappearing with age. The 
species has been found in abundance at Cape San Lucas, 
Altata and Guaymas, but has not been noticed further 
south. 
Adult greenish above, belly coppery pink; head olive, 
sides with eight cross bands of warm brown, unequally 
placed; fins dusky olive shaded with pinkish and brown; 
ventrals black tipped. A dark crescent at base of pec- 
toral. 
124. Lutianus novemfasciatus Gill. Parco PRIETO. 
Parco MARENO. 
This species reaches a much larger size than any other 
members of the genus on the Pacific Coast, those speci- 
mens obtained by us with dynamite among the Venados 
Islands having a weight of about twenty-five pounds. It 
is a food fish of some importance. It undergoes very 
considerable changes with age, as the notes below will 
show. The young are dark in color, the bodies banded 
and the amount of red very slight. The adult becomes 
uniformly colored with much red, and with increased age 
there is a progressive lengthening of the snout and widen- 
ing of the preorbital.
