Remarks

Although in his revision of the family, Broch (1958) synonymized Umbellula dura Thomson & Henderson, 1906 with Umbellula durissima Kölliker, 1880 and Umbellula rosea Thomson & Henderson, 1906 with Umbellula thomsoni Kölliker, 1880, we consider that, based on the original descriptions and images of U. dura and U. rosea, those species have important morphological characters to compare with our specimens.
