projecled. The anterior rays of dorsal and anal elon<^ated. First 

 and second dorsal spines very short; the third greatl>- produced, 

 ending in a filament about as long as the fish. Pecflorals about 

 equal in length to the ventrals. Caudal peduncle unarmed. Fins: 

 Caudal lunate. Pe(5lorals about equal to length of snout. Ventrals 

 (including filament) about the same length as anal. Colors: Yel- 

 lowish white with three broad, dark, vertical bands, the anterior 

 one forming a somewhat oblique line with anterior of orbit to sec- 

 ond dorsal spine, and extending to midway between pecflorals and 

 anal: the second extends from the bases of 5-25 anal rays to about 

 8-23 dorsal rays; this dark band broadens out on the anal fin, while 

 on the dorsal it contracts to a point; there is also a narrow line of 

 white in the posterior part of this dark band; the third dark band 

 includes the base of caudal peduncle and abovit all of caudal fin. 

 The anterior one of these broad black bands is traversed b}- two 

 more or less distinct narrow blue lines; in larger specimens these 

 are almost obsolete, excepting the line which extends from anterior 

 ba.se of peclorals to the gill openings. A dusky stripe extends from 

 the Ashaped narrow blue line above and on a line with the middle 

 of orbit to the tip of the snout; half-way between orbit and tip of 

 snout a black line branches off on each side from this dusky frontal 

 band, and unites with two other dark lines given off near the pre- 

 maxillar}', to form a right-angle triangle on each side of the snout. 

 Lower jaw mostly black. Eight specimens, from 2.75-5.25 inches 

 in length, were secured inside the coral reef. Agaiia, Guam, July 

 15, 1900. Hab. This is a common and wide-ranging form extend- 

 ing from East Indies and Polynesian islands to Revillagigedo Archi- 

 pelago on the ea.st to western Pacific, Marianas.

Head, exclusive of flap, 4; depth 1.86; eye 3.50; the preopercle 

 spine smooth, slightly curved, reaching to base of pedtorals, 2 into 

 head ; interorbital equal to eye ; snout 2 into head; D. xiv 15; 

 A. Ill 16; V. I 5. Scales 48. Preopercle serrated, the strong .spine 

 at its lower angle directed back. Teeth setiform. Branchioste- 

 gals 6. Scales small, and mixed with these are many minute ones. 

 Body elevated and strongly compressed. Fins: Caudal rounded. 

 The spinous dorsal commences above the opercles. The pectorals 

 and ventrals each equal to length of head. Soft dorsal and anal 

 sub-angular posteriorly. Color in life: Yellow; a fine blue ring 

 around the ej^e and across interorbital; a blue line, as wide as 

 pupil, down the posterior edge of opercle. Fins vellow; dorsal, 

 caudal and anal with a fine marginal line of deep bluish black. 

 In spirits the color fades into a uniform 3'ellowish white with a blue 

 line around eye and down posterior margin of opercle; caudal, soft 

 dorsal and anal with a fine marginal line of black. Two specimens. 

 Length 5 inches. Guam, June 14 ,1900. Hab. Polynesia, Marianas.
