Citharichthys, Bleeker. 
A genus of pleuronectoid fishes. Mouth rather wide, the length of 
the maxillary almost one-third that of the head. Eyes upon left side, 
the upper one very near to profile. Teeth quite minute, on a single series 
in each jaw, rather more prominent upon the blind side. Vomerine and 
palatine teeth none. Pectoral fin upon blind side much shorter and 
with fewer rays than upon colored side. Ventrals also asymmetrical, 
the sinistral one upon the median ventral line, the dextral one slightly 
in advance and crowded up upon the blind side. Dorsal fin commences 
in front of the eye upon the snout. Dorsal and anal rays simple. Cau- 
dal fin subsessile, its peduncle not much developed. Seales large, flexi- 
ble, cycloid, very deciduous. Lateral line strongly defined, straight or 
very slightly curved anteriorly. Gill-rakers short, rather stout, flexible. 
Vertebre 34 (in C. arctifrons). Gill membranes broadly united below 
the throat; gill rakers lanceolate. Branchiostegals 5.
