The height of the body is 3| in the total length, the length of the 

 head 4| ; the diameter of the eye is 3 1 or 3| in the latter. The 

 fourth dorsal spine longest, rather longer than one-third of the height 

 of the body ; the second anal spine longer than the third. Yellow, 

 with nine bluish-white longitudinal bands edged with brown ; the 

 three upper ones running from the croAvn to the base of the dorsal 

 fin ; the fourth, fifth and sixth from the side of the head to the 

 caudal fin ; the seventh and eighth from the head to the anal ; the 

 ninth from the head to the belly. The caudal brownish violet, with 

 nine or ten oblique bluish-white streaks ; the other fins yellow ; 

 the pectorals with three brownish cross-bars ; the anal with two or

 specimen as a variety of D. j^oli/hvuioides;. It has six white 

 longitudinal bands only, but the same numbers of the fins, thf- 

 same spinous dorsal fin of nearly uniform j-ellow, and two cross- 

 bars on the pectorals.

 longer and stronger than the third. Above bluish ; on each side 

 eight orange-coloured longitudinal bands : the fii'st from the neck 

 along the base of the spinous dorsal, continuing on the soft portion

 the middle of the caudal ; the sixth from below the eye to the lower 

 half of the root of the caudal ; the seventh from the mouth to the
