The two specimens here noted, which are 9 in. long, differ slightly 

 from a small one from Bahia. The second anal spine is If in head 

 and does not quite reach the tips of the first two soft rays. The 

 anal basis is more nearly horizontal, the anterior profile is slightly 

 concave, the eye is shorter than snout, the teeth are smaller. The 

 depth is a little less than head. Soft dorsal and anal scarcely dotted 

 with darker ; brownish dots on sides as in B. armata.

A specimen 10s in. long has the following measurements: Head 



SI ; depth 3| ; D. X-I, 28 ; A. II, 8. The color is less silvery than 



that of specimens from Havana, but otherwise it is essentially the 



same. 



129. TJmbrina coroides Cuvier & Valenciennes.

Head 3£; depth 3* in length; eye 4f in head; scales 6-50-9;

Highest point of dorsal outline at anterior third of spinous dorsal, 

 the anterior outline more strongly curved. Mouth inferior, hori- 

 zontal or nearly so, teeth equal, in bands; barbel short, blunt; 

 width of preorbital equal to length of eye ; nostrils close together, 

 the posterior oblong, more than twice as large as anterior, situated 

 immediately in front of eye ; preopercle finely and evenly serrate 

 above angle ; opercle with two dull points, not extending to edge of 

 marginal membrane, the lower somewhat more acute, both evenly 

 projecting. The lobes and pores in front of the mouth well-de- 

 veloped. Pectorals as long as ventrals, If in head, inserted under 

 opercular membrane ; ventrals inserted behind pectorals, the outer 

 ray with a very fine filament. Third dorsal spine longest, 1\ in 

 head. Caudal slightly emarginate, the lower angle slightly rounded, 

 upper and longest rays If in head, or equal to head in front of oper-
