In my recent revision of the Sarothrogammarus-group (Bijdr. Dierk., 41: 94—129, 1971), I consistently used the spelling Sarathrogammarus. Professor S. Ruffo, of Verona, kindly pointed out to me that the original spelling of the name is Sarothrogammarus (see Martynov, 1935, Trav. Inst. zool. Acad. Sei. URSS. 2: 484—506). Though the etymology of the word is not very clear (perhaps from σαρω = to brush, to clean), it is evident that there are no good grounds for the spelling Sarathrogammarus, as used by me.
