Greenish above, sides and below golden; caudal peduncle dusky- 
above; dark opercular and axillary spots; inside of mouth black. Head 
rather deeper than long; opercles very short; snout short. Mouth very 
oblique; maxillary reaching anterior margin of eye; eye very large, 
longer than snout, about 3 in head. Caudal peduncle longer than 
deep, its diameter less than that of the eye; ventrals very small, fitting 
into a groove in which the vent is situated; pectorals long, falcate, one- 
third the length. Head 3f in length; depth 2^. D. VIII — I, 26; A.

Body compressed, moderately elevated, the general outline ovate. 
Caudal iieduucle short and rather slender. Abdomen not trenchant, 
shorter than the anal fin. Head moderately- comiiressed, very blunt, the 
snout abruptly truncate. Mouth nearly- horizontal, the maxillary reach- 
ing the middle of the eye; iiremaxillaries jirotractile ; maxillary with- 
out distinct supplemental bone. Jaws, vomer, and palatines with bands 
of villiform teeth, which are deciduous with age. Preopercle entire in 
the adult. Gill-rakers short. Gill-membranes considerably^ united. 
Spinous dorsal rei>resented by six rather low spines, which are con- 
nected by membrane in the young and are free in the adult. In old 
specimens the spines appear small on account of encroachments of the 
flesh, and ultimately often disappear. Second dorsal long, elevated in 
front; anal opposite to it and similar in form and size; two stout, uearly- 
free spines in front of anal, and one connected with the fin, these often dis- 
appearing with age. Scales small, smooth. Lateral line unarmed, little 
arched; no caudal keel. ‘‘When extremely- young the preoperculum is 
armed at the angle with three large spines, and smaller ones above and 
below. The spinous dorsal is developed as a perfect fin, and teeth are pres- 
ent on the jaws and palatine arch. In this stage the species bas never 
been described by- previous naturalists, and consequently has received no 
name, as the corresponding stage of Naucrates {Nauclerus) has. At an
