Dorsal XII, 16; anal II, 12; scales in lateral series 28; with 

 tubules 20 ; between lateral line and origin of dorsal 3 ; between 

 laferal line and vent 9. 



Body ovate, upper profile from origin of dorsal to snout 

 an even curve, depth 2.1 in length; head 3; depth of caudal 

 peduncle 6.3. Interorbital space slightly convex, its width 

 equal to length of snout, which is 3.1 in head or slightly longer 

 than diameter of round eye; snout rounded, with its tip on a 

 level with inferior margin of eye; mouth oblique; maxillary 

 ending posteriorly below front margin of orbit; teeth in two 

 rows, with slightly emarginate edges. Orbital ring at end 

 of maxillary nearly half as wide as the length of eye diameter; 

 preopercle finely serrated ; opercle with a flat blunt spine behind. 



There are no scales on the outer edges of preopercle ; a rather 

 high sheath of scales at base of vertical fins. Posterior half of 

 dorsal spines of nearly the same height. Soft dorsal and 

 anal highest along the middle, the former rounded and the latter 

 angular ; caudal forked ; pectoral not quite reaching vent ; ventral 

 extending to base of anal spines, its outer ray produced. 



In alcohol the color is olive brown, with a light brown streak 

 at the edge of each scale. The broad light vertical band across 

 middle of body between the posterior dorsal spines and the 

 anterior anal fin is rather distinct; the blue lines on sides of 

 head absent; a large, oblong, black spot occupying base of last 

 dorsal rays, and another one present superiorly at base of pecto- 

 ral. Ventrals and vertical fins blackish; outer portion of 

 caudal pale. 



The above account is that of two specimens, in the Stanford 

 University museum, collected by R. C. McGregor at Calayan 

 Island, Cagayan Province, as recorded by Jordan and Richard- 

 son. 



This species is rather rare in the Philippines and is found 

 from the Andamans throughout the Indo-Australasian Archi- 

 pelago to Palau Islands and Samoa.
