dd. Mouth not quite terminal, the preniaxillary anteriorly scarcely on level of 

 lower margin of orbit; preorbital narrow, but broader than in the pre- 

 ceding species. 



e. Dorsal rays X-I, 28 ; dorsal spines very slender, the highest 1£ in head ; 

 dorsal outline convex, especially anteriorly ; ventral outline straightish ; 

 profile straightish anteriorly ; eye moderate, as long as snout, 4£ in 

 head ; maxillary 2£ in head, reaching much beyond middle of eye ; 

 teeth in the upper jaw in a narrow band, the outer series enlarged ; 

 gill-rakers 8 + 19 J basal half of soft dorsal scaly ; anal spine very strong, 

 its tip reaching past tip of last anal ray; pectorals about equal the 

 ventrals, 1£ in head ; color grayish silvery above, silvery on sides and 

 below ; dorsal region with faint streaks produced by the darker centers 

 of the scales; sides without dots; spinous dorsal blackish; ventrals 

 and pectorals pale; a dark axillary spot; lining of gill cavity with 

 dusky blotches. Head 3£ in length; depth 3£. D. X-I, 28; A. II, 8. 

 Scales 8-51-10 Icistia, 43. 



ee. Dorsal rays X-I, 23; dorsal spines rather stiff, the highest 2 in head; 

 second anal spine rather strong, curved, If in head, as long as first soft 

 ray, and reaching beyond tips of other rays ; body oblong, compressed, 

 scarcely angular in outline ; profile straight, rather steep, the snout 

 short and raiher acute ; eye as long as snout, 4J in head; mouth mod- 

 erate, nearly horizontal ; preniaxillary on level of lower part of orbit ; 

 maxillary reaching beyond middle of eye, 2f in head ; teeth as in B. 

 icistia; preopercle strongly serrate; gill-rakers 9 + 18. Ventrals 

 slightly longer than pectorals, which are If in head; caudal truncate; 

 color soiled grayish above, silvery below ; faint, dark streaks along 

 the rows of scales ; spinous dorsal and anterior part of anal densely 

 covered with dark dots; head 3| in length; depth 3|. D. X-I, 23; A. 



II, 8. Scales 7-50-8 Ronchus, 44. 



aaa. Teeth of the lower jaw subequal in a rather narrow villiform band ; mouth in- 

 ferior or subiuferior, little oblique; preorbital broader, gill-rakers 

 shorter, and pores and slits on snout more conspicuous than in other 

 species. (Species approaching OpMoscion.) 

 f. Snout sharp, the head slender, narrow above, the interorbital space not 

 broader than eye ; anal spine very long and strong, If in head ; pec- 

 toral fin short, 1£ in head ; form of body irregularly rhomboidal, the 

 base of the anal fiu being oblique ; profile almost straight anteriorly ; 

 eye moderate, slightly shorter than snout, 4 J in head ; snout 4£ in head ; 

 mouth large, inferior, almost horizontal, maxillary reaching beyond 

 pupil, 2f in head ; upper jaw with a band of villiform teeth and an 

 outer series of enlarged teeth; lower teeth in a moderate band, the in- 

 ner series slightly enlarged, especially in young examples; gill-rakers 

 comparatively short, 8 + 15 ; dorsal spines short and stout, slightly 

 more than 2 in head ; caudal rounded ; anal spine If in head ; basal 

 half of the soft dorsal and anal covered with scales ; color, bluish above, 

 silvery below, a rather broad area from snout to caudal covered with 

 brownish dots ; upper fins and anterior half of anal with many dots. 

 Head 3 in length ; depth 3 ; D. XI-I, 21 ; A. II, 8. Scales 7-51-8. 



Armata, 45. 



ff. Snout bluntish; the head rather stout and broad above; the interorbital 



space more or less broader than eye; second anal spine stout, shortish, 



about half length of head. 



g. Dorsal rays X-I, 18 ; scales large, about 44 in the lateral line ; pectoral 



not longer than caudal, which is 1| in head ; body rather elongate . 



back a little elevated and compressed ; profile somewhat depressed
