512 A COLLECTION OF FISHES FROM SUMATRA. 



is 3-| inches long. It has profile less convex, a shorter pectoral, adipose eyelid little 

 developed, and ridge of preopercle more oblique. When received fresh in arrack 

 they were pale leaden-gray above, sides and lower portions white, everj'where 

 silvery. . Sides with five deep lead-colored vertical bands fading out below. Spinous 

 dorsal blackish. Opercle with a diffuse dusk}' blotch on its margin.

Head 2f ; depth If; D. VIII— 1, 22; A. II— I, 18; scales about 56 in curved 

 portion of lateral line, and about 32 in remaining short straight portion ; width of 

 head 2|- in its length ; depth of head 1 ; mandible l.^^ ; third dorsal spine 2|- ; sec- 

 ond dorsal ray If ; first anal ray 1^ ; least depth of caudal peduncle 7 ; pectoral 

 1^ ; ventral 2|- ; snout 3 in head, measured from its tip ; eye 3 ; maxillary 2\ ; 

 interorbital space 3^. 



Body short, deep, ellipsoid, greatly compressed, greatest depth at origin of soft 

 dorsal, and caudal peduncle small and compressed. Upper and lower profiles about 

 evenly convex anteriorly. 



Head large, deep, compressed, and rhomboid. Snout a little prominent, short, 

 compressed, oblique, blunt, and upper jaw scarcely projecting. Eye rather large, 

 in middle of length of head. No adipose eyelid. Mouth small, oblique, and man- 

 dible projecting beyond upper jaw. Maxillary small, its upper edge slipping under 

 preorbital anteriorly, and its distal expanded extremity, which is equal to half of 

 eye reaches opposite front rim of same. Teeth minute, equal, and forming narrow 

 bands of two or more series in jaws. Vomerine and palatine teeth reduced to 

 minute asperities, none on tongue. Tongue small, elongate, rounded and free in 

 front. Lips rather thin. Nostrils rounded, close together, high, and close to front 

 of eye above. Intei'orbital space narrow, elevated, and giving place to rather high 

 median trenchant ridge running to spinous dorsal. Preorbital broad, nearly equal 

 to eye. Two supraocular ridges running up from eye posteriorly. 



Gill-opening large, carried forward a little in front of nostrils. Gill-rakers 

 8 + 23, a little longer than filaments, pointed, compressed, about two and one-third 

 in eye. Pseudobranchia3 rather small. Isthmus narrowl}' compressed, and with 

 a narrow median groove. 



Scales minute, and narrowly imbricated. Breast naked, including base of pec- 

 toral. Base of spinous dorsal with a narrow scaly sheath, and basal scaly sheaths 

 along anterior portions of soft dorsal and anal. Base of caudal scaly, without keels 

 at bases of lobes. Lateral line strongly arched till about opposite middle of base of 

 soft dorsal, remaining straight portion armed with small weak scutes, broadest not 

 more than half least depth of caudal peduncle. Upper side of head posteriorly 

 and cheek scaled, rest of head naked. 



Origin of spinous dorsal well behind origin of pectoral, third spine longest, and 

 all depressable in a groove. Origin of soft dorsal midway between front rim of 

 orbit and base of caudal, anterior rays elongate, first developed longest, and last not
