Photomicrographs of National Mu- seum of Natural History (NMNH) type specimens of Membrendoecium strictorostris and Dacryonella typica of Canu and Bassler (Fig. 8) clearly indicate their similarity in morphology and size. As Canu and Bassler pointed out in the original description of M. strictorostris, "The micrometric measure- ments are quite variable, ranging from one to twice the size and have only an approxi- mate value. The gymnocyst is frequent but in no wise There are cases of total regeneration" (Canu and Bassler, 1928a, p. 23). In that case, the species name strictor- ostris, by appearing earliest in the publica- tion, has priority. The second reference to the species, as D. typica, appears in their Brazil paper, also published in 1928, but much later in the year. Canu and Bassler (1928a) made D. typica the Recent type species of Dacryonella. The species above is now considered, to fall in the genus Antro- pora, of which the accepted genotype is Antropora granulifera Hincks, described from the Las Perlas
