pupil; teeth in lower jaw in a villiform band, those on premaxillaries 

 similar, but with an outer row of enlarged, curved caninelike teeth, 

 these decreasing in size toward angles of mouth; vertical limb of 

 preopercle with 5 moderate spines, the lowermost strong, directed 

 downward; several spines on the horizontal limb of the preopercle, 

 these projecting but little below the integument; nostrils rather 

 small, the posterior close to orbit; gillrakers very long and slender, 

 6+24, the longest at angle of arch, 1.23 in eye. 



First dorsal spine very small, the fourth longest, 2.1 in head; 

 fourth to tenth growing shorter, eleventh to fourteenth again in- 

 creasing in length; all the spines rather weak; caudal subtruncate; 

 second anal spine considerably longer than first but shorter than 

 soft rays, 3 in head; ventrals not reaching vent, 1.4; pectoral long, 

 reaching to below origin of soft dorsal. Scales on body ctenoid, 

 those on head weakly ctenoid; soft parts of vertical fins scaled to 

 their tips. In life, this specimen was much darker and the stripes 

 more distinct than in individuals from Chimbote. Ground color 

 light, with dark stripes along rows of scales; 11 stripes dis- 

 tinguishable below the lateral line, seven above the pectoral; white 

 of belly extending up on lower part of sides for only one-fourth 

 inch; all fins rather dusky with only faint traces of yellowish orange; 

 faint reddish orange on ventrals. 



Color in spirits: Back very dark, sides lighter, becoming white on 

 ventral surface; centers of scales dark, these forming lines along 

 rows of scales; center of opercle with a dusky black area; vertical 

 fins dusky; paired fins lighter; base of pectoral dusky. Description 

 based on a specimen 15.9 cm. long from Pacasmayo. 



An individual from Chimbote has head 3.02 in length; depth 

 2.75; eye 5 in head; snout 3.8; maxillary 2.47; interorbital 3; pec- 

 toral 1.35; D. XIII, 20; A. II, 11. Color in life: There is some 

 variation in the coloration of this species, but a fish of ordinary 

 markings has the following coloration: Ground color light, espe- 

 cially below; belly and lower part of sides for three-fourths of an 

 inch or more, white; inconspicuous stripes (6-f-) below the lateral 

 line, five of these being above the pectoral; other stripes above the 

 lateral line, but they are seen very indistinctly in the darker color- 

 ing of the upper part of body. Fins (anal, pectoral, and caudal) 

 yellowish orange, somewhat dusky, pectoral with some reddish 

 orange; ventrals reddish orange with hardly any duskiness. 



We are unable to find sufficient differences between Corvina 

 agmsisii of Steindachner and Corvina minor of Tschudi to separate 

 the two and believe that they are one. 



This species is found along the coast of Peru, and is most nearly 

 related to Stellifer illecebrosus Gilbert, from Panama Bay.
