A COLLECTION OF FISHES FPvOM SUMATRA. 509 



Length 8^ inches. 



Type No.^27,502, A. N. S. P. Padang. 



One example, which resembles Caranx macrurus (Bleeker). C. djedaba (For- 

 skal), and C. vialam (Bleeker). These are all grouped among the species oi Selar 

 apparently on account of the presence of palatine, vomerine, and lingual teeth. It 

 is not possible to determine the width of the maxillary from the descriptions given. 



{Glabra, smooth.) 



RASTRUM subgen. nov. 

 Type Alepes scUula sp. nov. 



Scales rather large. Vomerine teeth in a small patch. Maxillary about a 

 third of orbit, in this apparently' different from Alepes. 



[Rastruni, a rake or harrow, with reference to the vomerine teeth.) 



71. Alepes scitula sp. nov. Plate X, lower figure. 



Head 3f; depth 2|; D. VIII — 1, 24; A. II — I, 20; P. ii, 20; V. I, 5; 

 scales 32 in curved portion of lateral line, remaining straight portion with 45 

 scutes ; about 10 scales between origin of spinous dorsal and upper curve of lateral 

 line ; width of head 2-i- in its length ; depth of head I-i- ; mandible 2^ ; third dorsal 

 spine 2i ; second dorsal ray 2 ; second anal ray 1\ ; least depth of caudal peduncle 

 h\ ; snout 2| in head, from its tip ; e3^e o|- ; maxillary 2|- ; interorbital space 3-|-. 



Body moderately long, compressed, fusiform, and anterior profiles evenly con- 

 vex. Greatest depth at origin of soft dorsal. Caudal peduncle long, its depth nearly 

 two in its length, and its width one and one-half. 



Head rather small, compressed, rhomboid, and rather blunt anteriorly. Snout 

 short, convex, and with upper jaw projecting. Eye small, anterior, and with a 

 broad posterior adipose eyelid. Mouth oblique, mandible projecting beyond upper 

 jaw, and maxillary slipping below preorbital' for a good portion of its length. 

 Maxillary expanded distally till equal to two-fifths of orbit, and reaching posteriorly 

 nearly opposite front margin of pupil. Lips thin. Teeth minute, crowded, and 

 uniserial in jaws. Vomer with a small patch of teeth, but palatines smooth. 

 Tongue small, elongate, free and rounded in front, its upper surface with a few 

 small asperities. Nostrils small, high, close together, and much nearer front rim 

 of orbit than tip of snout. Preorbital broad, and with several radiating fiutings 

 from above. Interorbital space broad, and with a median keel which begins over 

 nostrils and extends up to spinous dorsal. Margin of preopercle strongly convex. 



Gill-opening deep, running forward below nostrils. Gill-rakers 12 + 30, long, 

 slender, compressed, and about equal to gill-filaments, or about two-thirds of eye- 

 diameter. Pseudobranchia3 small. Isthmus narrow, broadening posteriorly, and 

 not trenchant. 



Scales rather large, cycloid, and imbricated. Spinous dorsal with a low nar- 

 row basal sheath. Soft dorsal and anal with a rather broad basal sheath along 

 anterior basal half of fins at least. Base of ^caudal with small scales, but lobes 

 without basal keels. Upper side of head, opercle, and cheek, covered with small 

 scales, rest of head naked. Lateral line strongly arched at first, then running
