Nine species of Yabeina have been reported from British Columbia. On the basis of statistical study of specimens collected from Marble Canyon and Upper Hat Creek, it is concluded that our specimens as well as specimens of the nine species of "Yabeina" (Y. columbiana, Y. minuta, Y. obesa, Y. dawsoni, Y. gracilis, Y. dunbari, Y. cylindrica, Y. ampla and Y. parvula) belong to one species which should be referred to the genus Lepidolina. They are described under the species L. columbiana (Dawson).
