Described from a specimen from Jitsugetsutan, collected by T. 

 Aoki in August, 1916. 



Habitat: Restricted to Jitsugetsutan (Lake Candidius). 



Remarks: This species is most nearly allied to Culler sieboldi Dy- 

 bowski* from Amur Province. The differences are as follows: a lesser 

 number of scales in the lateral line, a lesser number of scales between 

 lateral line and the middle of belly, as well as small size of the body. 

 The above described species is one of the largest forms which is found 

 in Lake Candidius.
