Described from a specimen from Shori, Toyen. 



Habitat: The present species is not a native of Formosa. Propagated 

 artificially throughout the island. 



Remarks: Aristichtyhs nobilis is a native of Southern China. Its 

 young which are collected in the rivers near Swatow, Amoy, or Foo- 

 chow are imported to Formosa and are bred in ponds, mingling with 

 Hypophthalmichthys molitrix. Sometimes it reaches an enormous 

 size, though it never spawns in Formosa.
