 & Scale but differs from this in having scaly nape and in the shorter 

 maxillary which does not extend to the anterior rim of orbit. 



Four specimens were collected from fresh-water in Kanazawa, 

 Kaga, by Mr. K. Katö, instructor of natural history in the Middle 

 School of that district, for whoirTthe species is named. The type, 

 6.1 cm. long without caudal, is contained in the Zoological Museum, 

 Science College, the register number being 2002. The species is 

 locally known by the name of "Kin-kan," the meaning of which is 

 uncertain.
