Micropogon Cuvier &, Valenciennes, Hist. Nat. Poiss., v, 213, 1830 (Uneatus= 

 fur ii ieri.) 



Type: Micropogon lineatus (Juy. & Val.= Umbrina furnieri Desmarest. 

 The species of this well-marked genus are very closely related and 

 are all American. 



ANALYSIS OF SPECIES OF MICROPOGON. 



a. Dorsal rays X-1, 28 to 30. 



b. Scales comparatively small, about 9 in a vertical series between front of dorsal 

 and lateral line, 12 in an oblique series ; outer teeth of upper jaw evidently 

 enlarged ; dark spots on scales above lateral line not forming continuous 

 stripes ; 16 scales iu an oblique series from vent upward aud forward to lateral 

 line. Body rather robust, the back elevated ; profile regularly rounded, 

 scarcely depressed above eyes ; snout 3 in head ; eye 5 in head ; preorbital 

 broader than eye ; preopercle strongly serrate along its whole posterior mar- 

 gin ; maxillary reaching front of pupil, 3 in head ; gill-rakers slender, very 

 short, numerous, about 7 4- 16 ; third dorsal spine 2 in head ; pectoral If in
