AHT. 19. NEW SPECIES OF FISHES FOWLER AND BEAN. 15 



Gill-opening forward opposite hind nostril. Gill-rakers 15-^20, 

 slender, lanceolate. If in filaments, which are long as eye. Pseudo- 

 branchiae half of gill-filaments. 



Scales in oblique rows above lateral lines, becoming horizontal 

 behind, and rows below all horizontal. Scales become smaller along 

 body edges, head above and below, and on breast. Caudal base 

 scaly, fin covered with fine scales. Soft dorsal and anal, each with 

 narrow basal strip of fine scales. Cheek with 16 rows of scales. 

 Snout, j)reorbital, maxillary, and lips naked. Scales with 11 basal 

 radiating striae, apical denticles 39 to 46 and circuli moderately fine. 

 Lateral line largely concurrent with dorsal profile, inclined little at 

 first along caudal peduncle side until midway at caudal base; tubes 

 small, simple. 



Spinous dorsal inserted close behind pectoral base; fourth spine 

 longest and last spine twice first ; fin edge entire. Soft dorsal origin 

 slightly nearer that of spinous dorsal than caudal base; front rays 

 elevated, but without distinct lobe. Spinous anal inserted nearly 

 midway between fifth dorsal spine base and caudal base; spines 

 graduated to last, though second but very slightly less than third. 

 Soft anal like soft dorsal, only much shorter. Caudal emargi- 

 nate, pointed lobes about equal. Pectoral falcate, reaches two-thirds 

 to anal. Ventral inserted close behind pectoral base, halfway to 

 vent. 



Color in alcohol dull olive-brown, sides and below paler. Follow- 

 ing courses of scales above lateral line a dark median line on each 

 row, at least wide as pale interspaces; these lines oblique on anterior 

 half of back, more or less horizontal on posterior portion. Below 

 horizontal dark lines, equally wide, though fewer; some cross lat- 

 eral line posteriorly and more or less traverse junctures of scales. 

 Fins all deep brownish. Pectoral axil slaty. Iris brown. 



Length 250 mm. 



Type.— Cat. No. 83484, U.S.N.M., Peru ? Wilkes Exploring Ex- 

 pedition. 



Only the type known. It differs from the known species of the 

 genus in the increased gill-rakers. 



(PajSScoTos, streaked.) 



Ctenosciaena, new subgenus. 



Type. — Sciaena duhia, new species. 



Differs from the subgenus Sciaena in the" slender, elongate, lanceo- 

 late gill-rakers, which are at least as long as longest filaments. Other 

 chai*acters in combination, are the apparently ctenoid scales (of which 

 but few remain); minute teeth, in narrow bands; long maxillary, 

 reaching nearly to hind eye edge ; presence of a well-developed single 

 barbel at chin; reduced soft dorsal rays; presence of 2 anal spines,
