 (1877) 79; Atlas Ichth. 9 (1878) pi. 404, fig. 5. 



Dorsal XIII, 13 or 14 ; anal II, 13 or 14 ; scales in lateral series 

 26; with tubules 15 to 18; between lateral line and origin of 

 dorsal 4 ; between lateral line and vent 10. 



Body oblong, a little elongate, profiles similar; depth 2.1 to 

 2.3 in length; head 3.1 to 3.4; depth of caudal peduncle 5.5 to 

 6.1. Interorbital space strongly convex and moderately wide, 

 being 3.2 to 3.8 in length of head or a little wider than the 

 diameter of the small, round eye, which is contained 3.8 to 4.1 

 in head; snout long and slightly pointed, decidedly longer 

 than either maxillary or diameter of orbit, being 2.5 to 2.9 

 in head, its tip below the horizontal line passing through 

 inferior margin of eye. Mouth small, almost horizontal; max- 

 illary 3.2 to 3.5 in head, ending posteriorly a trifle behind nos- 

 trils, teeth in a double series, compressed, with slightly rounded 

 tips. Width of preorbital above posterior end of maxillary 

 nearly equal to diameter of eye; suborbital and posterior 

 edge of preopercle strongly and evenly serrated; opercle with a 

 flat spine behind. 



Snout in front of nostrils, orbital ring and vertical limb of 

 preopercle bone naked. Dorsal spines evenly graduated to the 

 last, which is as high as second anal spine. Rayed dorsal and 

 anal slightly angular and of nearly the same height; ventral 

 longer than pectoral, ending opposite vent. 



Color in spirits yellowish, with three large blackish spots 

 along back; one at origin of dorsal fin; the second below the 

 seventh, eighth, ninth, and tenth spines; the third at the base 

 of the last dorsal rays; the last two spots disappearing below 

 lateral line. A light band on nape ; two bluish lines across inter- 

 orbital; another along suborbital, extending into more or less 

 connected dots on preorbital; some scattered bluish spots on 

 sides of head and on scales of vertical fins, and a narrow trans- 

 verse streak of the same color on each scale of body. Anal witn 

 a longitudinal stripe along the middle, dorsal with two. A dark 

 blotch surrounding vent and none on axil of pectoral. 



The fourteen Bureau of Science specimens above described 

 measure 41 to 120 millimeters in length, and were collected at 

 Puerto Galera, Mindoro; Busuanga Island; Halsey Harbor, Cu-
