In order to ensure stability of nomenclature among species of Gondolella, we select lectotypes from among the cotypes (syntypes in modern usage) proposed by Stauffer and Plummer (1932) for species that we conclude were parts of the apparatuses of two species of that genus. We recognize that many of their specimens actually represent growth stages of individual species, and we place many of the names used by Stauffer and Plummer in synonymy. Thus, Gondolella bella has synonyms G. curvata, G. magna, G. minuta, probably G. sp. A, Euprioniodina coronata, E. exserta, E. eximia,and E. intertexta. In a similar manner, the type species of the genus, Gondolella elegantula, has synonyms G. insolita, G. lanceolata, and Euprioniodina sp. B.
