margin ; the seventh ray shortest, 2-$- in second or longest ray. Anal sim- 

 ilar to soft dorsal but more concave. Pectoral reaching very nearly to 

 front of spinous dorsal. Caudal forked. Color dusky above, with bluish 

 reflections , silvery below ; no dusky streaks along sides ; spinous and 

 soft dorsal dusky, the latter finely punctulate with brown, its anterior 

 rays tipped with black; Caudal pale, broadly margined with black; 

 anal pale, its basal half appearing dusky from dark punctulations ; pec- 

 toral pale in front, rather dusky behind, where there is a dusky blotch at 

 base. Length 11 inches. Florida Keys to Cuba ; not abundant, but com- 

 mon at Key West. (Named for P. Gaimard, the associate of Quoy, in the 

 study of the animals obtained on Freycinet's voyage of the Uranie and 

 the Physicienne, and on Dumont d'Urville's voyage of the Astrolabe.)

1189. MUGIL SETOSUS, Gilbert. 



Head 3f to 3f in length ; depth 4 ; eye large, equaling or slightly excsed- 

 ing the length of the snout, 3* to 4 in head, If in interorbital width. D. 

 IV-I, 8; A. Ill, 9; scales 37. Closely resembling Mugil hospes, from 

 which it differs widely in its much larger multiserial setae, and the 

 longer, narrower mouth. Mandibular angle less than 90 degrees; length 

 of cleft of mouth but little less than its width. Premaxillary setae in 

 a narrow band, not arranged in definite cross lines as in Chasnomugil j those 

 of outer row very long and numerous, curved and closely crowded ; inner 

 sette much shorter, but arranged in several irregular series ; mandibular 

 setse shorter and slenderer but larger than the premaxillary setae of M. 

 curema ; in a single series ; a narrow strip only of the maxillary is visible 

 in the closed mouth. Upper lip thick. Preorbital denticulated. Adipose 

 eyelid partly covering pupil, but much thinner than in curema and related 

 species, the whole eye being visible through it in alcoholic specimens; 

 adipose mass lying behind eye less developed, encroaching but little on 

 the opercle. Suborbital very wide, as in Mugil trichodon. Scales moderate, 

 20 in front of dorsal, 11 in an oblique series from vent to base of dorsal. 

 Accessory scale on each side of spiuous dorsal usually longer than the 

 base of the fin. Axillary scale exceedingly thin and membranous. Soft 

 portions of all the vertical fins scaled to tip ; basal portions of the pec- 

 torals and ventrals also scaled. Pectoral long, pointed, slightly falcate, 

 as long as head behind front of pupil, reaching tenth or eleventh scale on 

 sides, failing to reach front of spinous dorsal by about & its own length. 

 Spinous dorsal lower than soft dorsal. Both soft dorsal and anal strongly 

 falcate, the last rays much higher than middle rays, the anterior rays when 

 depressed nearly reaching tips of last rays. Soft dorsal inserted over fourth 

 or fifth ray of anal. Caudal longer than head, the lobes long and pointed. 

 Plain grayish above, silvery on sides and below, without stripes or other 

 markings. Ventrals unmarked, the other fins slightly dusky, the caudal 

 with a distinct black margin. Very abundant at Clarion Island, of the 

 Revillagigedo group, also found at Mazatlan, where the color is much
