CHRYSIPTERA 105 



of orbit; snout equal to width of interorbital space. Teeth in 

 two rows with slightly rounded edges. Greatest width of or- 

 bital ring scarcely half diameter of eye; opercle with two flat 

 spines behind. 



No scales on the area between nostrils and tip of snout; 

 none on orbitals, edges of preopercle, and chin. Middle dorsal 

 spines as high as posterior ones. Soft anal slightly higher and 

 more pointed than rayed dorsal; caudal slightly emarginate; 

 ventral ending at vent. 



Fresh specimens, dusky olive, with three- crossbands ; the first 

 one over the opercle yellowish orange, and two others above vent 

 and across caudal peduncle lemon yellow. Ventrals and anal 

 dusky ; soft dorsal and caudal dusky at base and yellowish orange 

 outward; spinous dorsal with a very narrow blackish margin; 

 pectoral very slightly washed with yellow, with a dusky blotch 

 at base ; the opercular flap above the larger spine blackish. 



Here described from four specimens, 32.5 to 45 millimeters 

 long, collected at Paraoir, Balaoan, and Bauang Sur, La Union. 

 I have examined in the museum of Stanford University three 

 other examples of this species, collected by R. C. McGregor at 

 Calayan Island, as recorded by Jordan and Richardson. 



Giinther regards this species as Glyphisodon brownriggii var. 

 xanthozona, from which the species above described differs in 

 the relative position of the second vertical band on the body. 

 It differs also from xanthozona of Bleeker in having fewer 

 crossbands and in the absence of a distinct dark blotch at the 

 base of some of the dorsal rays. 



This species is known throughout the tropical Pacific Islands.
