1) Goldfishes and carps were arranged in three groups, namely of normal ones, of blind ones, and of blind ones of which lateral lines had been removed and the receptors of facial nerves had been incinerated. Their localization against the stream direction was studied. 2) As for goldfishes and the carps the blindness seemed to have caused some difficulties in localizing them against stream. 3) When blind goldfishes or carps shifted to the region where the direction and the velocity were somewhat different from the main stream, it seemed easier for them to localize themselves against it. 4) When the lateral lines of blind carps had been removed, a great difficulty was observed for them in localizing themselves against stream. But when their bodies contacted some fixed objects, the counter-stream localization was observed. 5) Blind carps whose lateral lines had been removed, and whose tactile organs in their faces had been incinerated could never localize themselves against stream. 6) No significant difference was observed between the ability of counter-stream localization of a goldfish and that of a carp.
