Type.—Imperfect fish; Paris Museum of Natural History. 
Of this rare and imperfectly known species a single small example is preserved 
in the British Museum, and one measuring 15 cm. in total length in the Carnegie 
Museum (Cat. No. 4013, 4013a). 
Division C. PERCIFORMES. 
The principal characters of this large division are thus summarized by Dr. 
Boulenger: “‘ Rays of the caudal fin not strongly forked at the base; hypural usually 
with a basal spine or knob-like process on each side, epipleural bones usually in- 
serted on the parapophyses or on the ribs; dorsal fin usually with strong spines; 
caudal peduncle rarely much constricted.” (loc. cit. p. 651.) 
Family Percipa. 
For figures of skulls and notes on the osteology of recent Percide see G. A. 
Boulenger, “Catalogue of the Perciform Fishes in the British Museum.” 
Genus Largs Cuvier and Valenciennes. 
The existing species of this genus are tropical fresh-water forms.
