The species of ‘^Scicvna'^ Avhich have the preopercle without bony 
serratnres may be referred to Corvina. Genus 296 [b), Boncador should 
])robably be retained also.

(Blof*!! Ichthvologia, about 1790; type Eques americaints Bloch.) 
Body oblong’, compressed, the back much elevated anteriorly. Mouth 
rather small, the lower jaw included; teeth in villiform bands, the outer 
somewhat enlarged above; preopercle serrate, the teeth flexible; pseu- 
dobranchite present. Scales moderate, extending on the soft fins, 
hflrst dorsal of about 16 spines, the median spines much elevated ; 
second dorsal extremely long. Anal very small; second anal spine 
small. Pyloric coeca few. Air-bladder simple. Yertebrse 10-fl5. 
{hatiu, Bquus, a horse; the long dorsal spines being compared to a 
rider.)

Greyish-yellow, with three broad blackish-brown bands, edged with 
whitish ; the first vertical, from the crown, through the eye to the angle 
of the mouth ; the second slightly arched, from the nape over the oper- 
cle to the base of the ventral; the third curved, from the top of the 
first dorspl along the middle of the side of the body to the middle of 
the caudal fin. Head small; maxillary 3 in head, reaching pupil. 
Height of first dorsal usually much more than depth of body below 
it. Head 3f ; depth 3^. D. XYI-I, 53; A. II, 10; Lat. 1. 60. West

L. in part, the species having been confounded by L. with Seiwna umbra (=aquHa 
Lac.). The enlargement of the second anal spine, used by Cuvier to distinguish Cor- 
vina from Scicena, has no taxonomic value. {Corrina, the Italian and Spanish name for 
various Scimnoids, originally from Latin Corvus, crow, in allusion to the dusky color of 
C. nigra.)
