caudal base, first spine about half length of second. Soft anal like 

 soft dorsal. Caudal moderately emarginate behind. Pectoral 

 long, about reaches anal. Ventral inserted close behind pectoral 

 base, first ray ends in filament reaching second anal spine base. 

 Vent close before anal. 



Color in alcohol largely uniform brownish above, much paler 

 below. Fins all largely pale, though marginal portions of spinous 

 dorsal and anal dusky. Caudal pale to whitish. Very small dusky 

 spot on uppermost scale of opercle. Another dusky spot, similar 

 and about half size of pupil, at uppermost pectoral ray basally and 

 above. Vent dusky. Iris slaty. 



Length 56 mm.

Philippine Islands. Presented by the Commercial Museums of 

 Philadelphia. 



Also Nos. 47,520 to 47,525, paratypes, same data. These show: 

 Head 3 to 3^; depth If to 2; D. XIII, 13, i occasionally XIII, 14, i 

 or XIII, 15, i; A. II, 14, i sometimes II, 12, i or II, 13, i; tubes in 

 upper arch of 1.1. 17, vary 14, 15 and 16; pores in straight section 

 of 1.1. 8; snout 3| to 3f in head; eye 2| to 2f ; maxillary 2f to 3; inter- 

 orbital 2f to 3|; length 43 to 54 mm. In these examples dusky 

 vent quite characteristic. 



Similar to Pomacentrus moluccensis Bleeker, but without a pale 

 lengthwise line across anals, as shown in Bleeker's figure.^* The 

 latter also does not inchcate a suborbital spine, which well developed 

 in all of my examples. 



(Named for Mr. Morgan Hebard of Philadelphia, an earnest 

 student of Orthoptera, to whom I am indebted for small collections 

 of fishes.)

 to caudal base; 3 scales above 1.1. to spinous dorsal origin, and 9
