into long filaments; 1.3 times length of body; anal similar to soft 

 dorsal with the anterior rays somewhat produced, about one-third 

 length of body; caudal peduncle unarmed; caudal fin lunate; pec- 

 torals short; ventrals pointed; posterior dorsal rays short, vertical 

 or even inclined forward; pedtorals longer than the snout; ventrals 

 filamentous, half length of body; a short recurved spine on the side 

 of the snout above the angle of the mouth. 



Color in formalin X alcohol. General color, silvery gray; an 

 obscure, dark, subcutaneous band the width of the eye extends 

 over the interorbital region; upper and lower lip blackish; distal 

 end of caudal peduncle blackish when held to the light; caudal 

 terminating in a pale crescent-shaped band. 



Color (based on plaster cast colored from life). Body, silvery, 

 with a greenish sheen; a green splash above the eye; lips blackish; 

 caudal peduncle greenish and olive; elongated dorsal rays black, 

 remaining rays smoky, with the edge of the fin yellow; anal smoky 

 brown, with a narrow yellow edge on its posterior margin; ven- 

 trals smoky brown, varied with an olive wash; pectorals colorless; 

 caudal smoky brown, like the anal, and terminating in a lunate 

 band of yellow. 



The fish from which the cast was colored was secured in the 

 Honolulu market, October 4, 1903, and measures 2.75 inches in 

 length. Type B. P. Bishop Museum No. 3359. (Fig- 2.) 



This species seems to be a Zancliis, and does not differ much

 ordinary "Moorish Idol".
