420 EEPORT OF COMMISSIONER OF FISH AND FISHERIES. [78] 



We find ourselves unable to follow Bleeker in using the name Sciwna 

 for the group usually called Umbrina, for reasons which may be again 

 briefly stated. Scicena was originally (Artedi, 1738; Linnaeus, 1758) 

 founded on the typical species of the two modern genera Umbrina and 

 Corvina. In 1817, Umbrina was set oft' from this group and Sciwna was 

 made to apply to the group later called Corvina, a third species 

 (aquila) being added to Scicena. Later (1829) Corvina was separated 

 by Cuvier. This gave Umbrina, Corvina, and Scicena, the latter name 

 then standing for aquila. In 1862, Bleeker proposed to use Scicena for 

 the type of Umbrina, because in enumerating his species of Scicena, Ar- 

 tedi had made the Umbrina li ?$o. 1" and the Corvina "No. 2." This 

 is, however, a matter of no significance. In our view but one arrange- 

 ment of these names is allowable. Umbrina must stand, Sciwna must 

 take the place of Corvina, and the third species (aquila) must take a 

 new name — Pseuclosciwna Bleeker. 



ANALYSIS OF SPECIES OP UMBRINA. 



a. Dorsal rays X-I, 22 to 24. 

 I. Snout moderate, 3J in head ; stripes on body yellowish, bordered with steel blue ; 

 preopercle with its bony margin distinctly serrate, the teeth at the angle 

 broad and flattish. Body rather deep, the back elevated, the dorsal out- 

 line regularly rounded, highest at first dorsal spines; profile steep ; snout 

 low, bluntish, 3J- in head ; eye small, If in snout, 1^ in interorbital area, 

 about 5$ in head ; mouth moderate, inferior ; maxillary reaching front of 

 eye, 3i in head ; preorbital one-third broader than eye ; teeth villiform, 

 in broad bands, the outer above little enlarged; lower pharyngeal teeth 

 stout, conical, the inner posterior series slender. Spinous dorsal high 

 the third spine 1^ in head; soft dorsal scaleless; second anal spine 

 small, If in soft rays, 2] in head; pectorals little shorter than ventrals, 

 which are If in head ; caudal slightly lunate, the upper lobe the longer. 

 Color olivaceous, silvery below ; upper parts with many wavy lines, yel- 

 lowish in color, and each bordered on each side by a distiuct streak of 

 steel blue ; the lines partly following the rows of scales, running nearly 

 straight upward and backwards at the shoulders, more nearly horizontal, 

 more irregular and more or less broken posteriorly ; free membrane of 

 opercle jet black within and without ; gill cavity pale. Head 3-^ in length ; 

 depth 3& to 'Si. D. X-I, 22 to 24 ; A. II, 7 ; scales 9-51 (pores)-12 ; about 



65 transverse series of scales Cikkosa, 87. 



J>1>. [Snout very short, 4A in head ; stripes on body dusky. Body somewhat elon- 

 gate; the ventral outline straightish, dorsal outline elevated and much 

 convex ; profile steep and convex, slightly depressed over the eyes ; snout 

 bluntish, 41 in head ; eye 6 in head, about equal to the broad preorbital ; 

 mouth subinferior, horizontal ; maxillary reaching past middle of eye, 

 3| in head ; barbel very short ; dorsal spines rather strong, the longest 

 2£ in head; anterior dorsal rays highest ; base of membrane scaly; cau- 

 dal slightly lunate ; anal spine very strong, 3 in head ; ventrals shorter 

 than pectorals, which are 1£ in head; scales very thin, covered with mi- 

 nute scales on their base ; scales below the lateral line in horizontal series ; 

 lateral line regularly arched to above posterior margin of anal. Coloration 

 much as in Micropogon undulatus : conspicuous undulating black lines fol- 

 low the aeries of scales on whole of boby above the pectoral ; pectoral, ven- 

 tral, and anal blackish, with broad whitish margin. Head 3^ in length ; 

 depth 3. D. IX-I, 24 ; A. 11,9; scales 6-60 (about)-lO.] (GUnther.) 



Reedi, 88.
