Eighteen examples of this species were taken by me, the majority being caught by means of a 
dip-net, on the reef in front of Honolulu. They range from 1.3 to 4.7 inches in length. In the 
smallest the white spot on the side of the body is 0.7 as broad as the head and extends from near 
the dorsal down the side more than 0.7 of its width, the remainder of the body being black. These 
specimens form a complete series, which show in the smallest the white spot relatively large and dis- 
tinct, being very conspicuous; in the largest it gradually becomes less distinct and relatively smaller 
In the largest the general color is gray, becoming almost white in some. A nuchal spot can not be 
distinguished in any of these specimens. The series also shows a gradation in length of second and 
last dorsal spines. One fresh specimen (field No. 259) showed each scale on the body pale blue with 
posterior margin black; head and fins all black; iris pale blue; white spot on side, 5 scales wide and (> 
scales deep, is under bases of sixth to tenth spines.
