518 SFIALK. 



origin of the ninth spine of dorsal, origin of anal is mucli nearer origin of 

 ventrals than to base of caudal, in fact, the distance between origin of 

 ventrals and anal is considerably less than base of anal. Origin of ventral 

 is midway between anal pore and a vertical line with posterioT' margin of 

 iri,?, the ventral rays are more or less prolonged and filamentous, reaching 

 to the origin of anal. Origin of pectorals is slightly anterior to origin of 

 ventrals. Candal lather long and sharp-pointed, scarcely emarginate, the 

 \ipper lobe the longer, being longer than head. 



Color in alcohol similar tn life color, except less bright being orange 

 yellow with a slight brownish wash on top of head, fading on shoulders 

 into the yellow body color. A blue line below eye on preopercle, some 

 blue spots on opercle, a blue line on side of snout, a blue line from 

 each side of belly out onto the anal fin where it forms a submarginal blue 

 band, the tips of the anterior anal J'ays being black, a naiTow black tip 

 to spinous dorsal, otherwise fins all bright yellow. A Ijlack dot at origin 

 of lateral line, another in upper axil of pectoral fin, lips dusky. 



Type is ISTo. 4737 from Sitanki Island, Jolo Archipelago. Taken by 

 C. Canonizado and the writer 15 July, 1908. Length, 7.50 millimeters 

 Five cotypes ISTo. 4736 were taken at the same time and place. 



This species is related to Pomaccntrus popei Evermann and Scale Imt 

 the coloring is different and the relative location of the anal and ventral 

 fins is quite different. It is also related to P. moluccensis Bleeker, but 

 has larger scales and a sharp-pointed caudal, with the additional dif- 

 ferences in color markings. 



Pomacentrus elongatus Seale, sp. iiov. Plate XH, fig. 2. 



Head 3.50; depth 2.15; dorsal XIII, 14; anal II, 15; scales 28, 18 

 pores in lateral line, 14 scales in vertical series; eye 3.10 in head; 

 snout 3.40; interorbital spiace 3; maxillary 3.40; mandible 3; pectoral 

 equal to head; ventrals longer than head; depth of caudal peduncle 2. 



Body oblong, compressed, rather elongate for this family. Greatest 

 depth in middle of body. Depth of caxxdal peduncle a fourth greater 

 than its length. 



Anterior profile from dorsal fin to snout evenly curved and about equal 

 to curve of thorax and chin. Interorbital space convex. Snout rounded, 

 its median width being slightly less than its length. Orbital ring strongh' 

 toothed, unsealed, very narrow below pupil, becoming wider under anterior 

 of eye, its width at angle of mouth 3 in eye. A rather strong spine at 

 posterior margin of this wide portion. Preopercle denticulate. MoutK 

 small. Maxillary ending under anterior margin of orbit. Mandible 

 ending under anterior margin of pupil. Teeth in two series the second 

 being smaller and less securely fixed and alternating with those of the 

 anterior series. Gill openings large, being carried forward to below 

 anterior margin of orbit. Gill rakers slender, aboiit 14 on lower limb. 



Scales covering entire body and head, except orbital ring and chin.
