Eemichromis auritus Gill, Proc. Acad. Nat. Sci. Phila., 1862, p. 135. 



Head, 2f to 2f ; depth, 2| to 2|: D. XIV, sometimes XV, rarely 

 XIII, 11, sometimes 12; A. Ill, 9; upper branch of lateral line, 16 to 

 20 scales; lower section, 9 to 12 to caudal base and 1 to 3 more on 

 latter; 4 scales above lateral line to spinous dorsal origin, 9 scales 

 helow to spinous anal origin, rarely 10; predorsal scales, 9 to 11; 

 snout, 2| to 3^ in head, measured from upper jaw tip; eye, 3f to 4f ; 

 maxillary, 2| to 3; interorbital, 3 to 3§. Elongately ellipsoid, 

 deepest at sixth dorsal spine base. Caudal peduncle well com- 

 pressed; length about three-fourths its least depth and latter 2^ in 

 total head length. Head width, 2^ its length. Snout conic, slightly 

 longer than broad, or broad as long in young. Eye little elevated, 

 hind pupil edge midway in head length, slightly advanced in young. 

 Maxillary about to eye, expansion about two-thirds of pupil. Teeth 

 conic, uniserial below and above, upper outer series well separated 

 from much smaller inner row; latter absent in young. Interorbital 

 broadly convex. Rakers, 1 or 2+8 to 10, anvil-shaped, about 

 two-thirds of filaments and latter 1^ in eye. Scales large, cycloid, 

 extend out over two-thirds of caudal; circuli fine and incomplete 

 apically; basal radiating striae, 10 or 11. Cheek with 4 or 5 rows 

 of scales. Small scales on breast like those on caudal base. Spinous 

 dorsal begins before pectoral; last spine, 2^ to 2§ in head; sixth dorsal 

 ray, 1§ to 2|. Anal begins about midway between pectoral origin 

 and caudal base; third spine about 3 in head; fourth anal ray, 1^ to 

 2|. Caudal convex behind, truncate in some examples, 1^ to 1^ 

 in head; pectoral. If to If; ventral. If, Color in alcohol generally 

 dull brow^nish above, paler to whitish below, sides with five large 

 vertical blotches of black, continued up over back narrower and 

 paler, and between them on side medially each scale with brownish 

 blotch at hind edge. Black blotch on opercle little smaller than eye, 

 with brownish area forward to latter. Iris gray-brown; soft vertical 

 fins often with few pale spots or blotches basally, upper caudal corner 

 and edge of soft dorsal sometimes whitish. Iris brownish. Length, 

 60 to 162 mm. One from Liberia (C.) also type of Hemicltromis auritus 

 Gill (S.), and 15 from Angola, as listed further on, 



HEMICHROMIS BIMACULATUS Gill. 



Head, 2-| to 2f ; depth, 2f to 2|; D, XJV, rarely XIII or XV, 11, 

 rarely 10; A. Ill, 8, rarely 7; scales 17 to 19 in upper section of 

 lateral line, 8 to 11 in lower section to caudal base, and 2 more on 

 latter; 3 or 4 scales above lateral line to spinous dorsal origin, 9 or 10
