AMPHIPRION 13 



arid maxillary equal in length, each 2.8 to 2.9 in head. Mouth 

 oblique, lower jaw slightly projecting, posterior end of maxillary 

 not quite touching vertical through anterior edge of orbit. A 

 single row of small, conical teeth present. Preorbital above hind 

 end of maxillary wider than half diameter of eye. Orbital ring 

 and vertical edge of preopercle strongly serrated, the anterior 

 spine of the former larger but not much longer than the rest 

 of the serrations. Opercle, subopercle, and interopercle with 

 radiated ridges ending in spines. 



Small scales covering head and body; interorbital, snout, or- 

 bital ring, and outer portion of opercle naked. Dorsal fin nearly 

 even, the posterior spines having almost the same height; soft 

 dorsal and anal pointed posteriorly and about equal in height; 

 caudal slightly emarginate in the adult and rounded in the 

 young. 



Brownish black in alcohol, lighter on chin and breast ; a pearl 

 white band edged with black descending over the opercles 

 immediately behind eye; caudal, pectoral, ventral, and vertical 

 fins yellowish. 



The above account is based upon five specimens, ranging 

 from 59 to 95 millimeters in length, two of which were collected 

 at San Fernando, La Union, and the others at Calapan, Min- 

 doro. 



Two living specimens in the Bureau of Science aquarium, 

 taken at Calapan, Mindoro, have the sides black which passes 

 into bright orange red toward anterior portion of head, and 

 toward breast, belly, vertical fins, and caudal; base and outer 

 portion of ventral black, the rest of the fin orange red; anal 

 spines black; pectoral bright orange red; the transverse band 

 behind eye bright pearl white, edged in front and behind with 

 black. A fresh specimen obtained at Tablas Island had the 

 sides black, fading into deep carmine red on anterior portion of 

 head and on breast, and toward the outward portions of dorsal, 

 anal, and caudal fins; base of pectoral black, the remaining 

 portion carmine red; ventral spine and rays black, the mem- 

 branes reddish; a bright, pearl white, black-edged transverse 

 band just behind eye. 



All the examples I have examined are fairly large and have 

 the pearl white transverse band on each side of head. Because 

 of the presence of this band I have placed this species as dis- 

 tinct from Amphiprion ephippium. Although the specimens 

 differ somewhat in the width of the vertical band and in the
