on larger scales. Caudal base scaly. Pectoral and ventral without axillary scales. 
Dorsal origin midway between front eye edge and caudal base ; third simple

ventral and caudal base ; first branched ray 2f. Caudal well forked, if in head. 
Pectoral very nearl^^ reaches ventral origin or about half way in ventral fins ; 
length i| in head. Ventral inserted well before dorsal, not quite reaching vent, 
length 2 in head. Vent close before anal. 
Olivaceous-brown above, with dusky cloudings, side and lower surface paler.

Hypophthalmichthys nobilis (Richardson). 
Head 3f ; depth 3; D. iii, 7, i; A. iii, 12, i; P. 11, 18; V. i, 7; 125 tubular 
scales in lateral Ime to caudal base; 33 scales above lateral line, 17 below to anal 
origin ; 58 predorsal scales; snout 3^ in head measured from upper jaw tip; eye 7?, ; 
maxillary 4^ ; interorbital 2 j. 
Body strongl}^ compressed, deep; abdominal keel extending from isthmus to 
vent, scales not passing over ; greatest depth at ventral origin. Caudal peduncle well 
compressed, long as deep or least depth 2| in head. 
Head moderate, robust, well compressed, width i its length; upper profile with 
upper jaw slightly protruding upward. Snout broadly convex, obtuse, length half 
width. Eye subinferior, faces downward, hind edge at fir.st third in head; 2| in 
snout or 3f in interorbital. Mouth with short gape, wide, closed jaws apparently 
about even. Maxillary little inclined from vertical, not reaching front nostril, largely 
covered by preorbital, its lower edge about level with eye centre. Edge of upper 
jaw firmly trenchant and mandible edge broadly obtuse. Tongue free, rounded, 
broad. Nostrils together, superior close before upper front eye edge well above e3'e ; 
hind one slit-like and larger. Interorbital convex. Preorbital nearly long as e^^e ; 
other suborbitals all narrow. Opercle with many fine radiating striae. 
Gill-opening extends forward midway in head (yill-rakers annectant, as fijie 
reticulations, about 704-280, equal gill-filaments on f of eye. No pseudobranchiae. 
Isthmus narrow, slender, lower surface level. 
Scales small, little smaller about edges of body, largest along lower side of trunk ; 
I to 3 weak apical radiating striae ; circuli fine. Caudal base scaly. Pectoral and 
ventral without axillary scales. 
Dorsal origin midway between front eye edge and caudal base ; third simple 
ray i| in head; first branched ray if. Anal inserted well behind dorsal base, or 
midway between ventral and caudal bases ; first branched ray 2 in head. Caudal 
well forked, if in head. Pectoral not quite reaching ventral, if in head. Ventral 
inserted well before dorsal, reaches f to anal, i-f^^ in head. Vent close before anal. 
Olivaceous-brown above, sides and below pale to whitish, with silvery tints. 
Back shows traces of greenish tints. Fins all brownish. One example, 324 mm.
