A single /specimen 119 millimeters long, type No. 6520 Leland 
Stanford Junior University Museum, taken in Matsushima Bay. It is 
very close to Urocampufi nanu,'<^ described from a single female speci- 
men from Manchuria; but that species has the rings 11 4- 50, appar- 
ently no barbels, a smooth operculum, and no anal fin, characters 
which, if authentic, may be of generic value.
