POMACENTRUS ELONGATUS Scale 



Pomacentrus elongatus SEALE, Philip. Journ. S<-i. A 4 (1909) 518, 

 pi. 12, fig. 2. 



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

 series 26; with tubules 18; between lateral line end origin of 

 dorsal 4 ; between lateral line and vent 10. 



Body elongate, dorsal outline evenly curved from tip of snout 

 to caudal peduncle, ventral outline similar to dorsal ; depth 2.2 

 to 2.3 in length; head 3.3 to 3.5; depth of caudal peduncle 6.7 

 to 7. Interorbital space convex, its width 3.1 to 3.3 in length 

 of head ; snout rounded, 3 to 3.1 in head or a little longer than 

 maxillary, which is contained 3.3 in head; eye rather small, 

 its diameter 3.8 in head. Mouth slightly oblique, jaws equal, 

 posterior end of maxillary below anterior edge of orbit; two 

 series of teeth in each jaw. Suborbital strongly denticulate, 

 first tooth enlarged and followed by a wide shallow notch; 

 opercle with two flat spines behind. 



Scales on top of head extending to nostrils, leaving a naked 

 space near tip of snout; orbital ring also naked; vertical fins 

 with a rather high sheath of scales at base. Dorsal spines 

 slender, becoming higher to the last; second anal spine higher 

 than last dorsal. Soft vertical fins about equal in height, with 

 their tips angular; caudal emarginate, with the lobes pointed; 

 pectoral almost as long as head, its tip above vent; ventrals 

 extending to origin of anal, its first ray filamentous. 



Deep brown in alcohol, with a black spot above opercle, a 

 bluish line above orbit, another one superiorly behind eye, a 

 short one across preorbital, and several rather indistinct bluish 

 spots on cheeks. Ventrals blackish, the other fins brownish.
