two uniting at gill-opening and running across opercle as one brassy line; anterior edge of operele 
bright indigo-blue. 
The above description based upon young individuals 2.5 to 4 inches long. The color of larger 
individuals, from Havana, has been described as follows: Light bluish-gray as ground color; a bronze- 
yellow spot on the upper part of each scale, these forming continuous undulating stripes on the whole 
body and head, wider than the interspaces of ground-color, and nearly straight on caudal peduncle, on 
anterior part of body below lateral line broader and very oblique; a horizontal golden- yellow stripe, 
crossing the others, runs alongside of back from occiput to last rays of soft dorsal; yellow around eye; 
yellow shades and streaks on cheek, not strongly marked as in II. sciurus and II. plumieri; yellow- 
stripes on top of head; angle of mouth black, inside brick-red; a large black blotch under angle of 
preopercle; fins bright golden-yellow, the pectoral and spinous dorsal paler. 
In spirits the ground-color becomes grayish and the stripes brotvnish or dusky. 
The range of II. flavolineatum is from the Bermudas, the Florida Keys, and Tortugas south to 
Brazil. It is generally common in the West Indies and abundant about Porto Bico, usually on sandy 
shores. No adults Avere obtained, but numerous young from the following localities: San Antonio 
Bridge, Mayaguez, Puerto Real, Ensenada del Boqueron, Ponce, Arroyo, Hucares, and Culebra. 
This Avell-marked species reaches a length of a foot and is a good food-fish.
