Height of the body equals the length of the head, and is slightly more 

 than one-fifth of the total length; eye not quite one-third of the length 

 of the head, and slightly longer than the snout; the jaws equal ante- 

 riorly, and the end of the superior extends beyond the vertical from the 

 anterior margin of the orbit. Teeth in a villiform band; an external 

 series of longer ones; a lateral canine tooth on each side of the lower 

 jaw, hooked backward. Prseoperculum armed at the angle with a group 

 of four small spines, coalescing by their bases. Scales ctenoid. Head 

 covered with large scales; snout, interorbital space and maxillaries 

 naked. The third dorsal spine produced into a filament; posterior rays 

 of soft dorsal and anal prolonged back to the base of the caudal fin. 

 The base of the anal ends before the termination of the dorsal, but its 

 last rays are longer, and extend as far back as those of the dorsal. 

 Ventrals commence under the base of the pectorals, and extend to the 

 commencement of the anal. Pectorals slightly longer than the ventrals. 

 Six blackish spots or bands along the sides of the body; each scale 

 with a blue spot (white in alcohol); fins minutely dotted. 



Lengths, 1.50, 1.15 inches. 



Locality : Coral reefs of Oahu. 



In 1862 Prof. T. Gill* made the interesting discovery that the young 

 of the Carangoids and Scombroids have the prseoperculum armed with 

 spines, which afterward become absorbed into the substance of the bone. 

 We have been mainly guided by this analogy in the identification of our
