Material examined. VMNH. no. 70635, 70636; USNM no. 1283249. Description. Colony encrusting unilaminar ( Fig. 23 A). Large, slightly convex zooids with smoothly calcified frontal wall with evenly spaced, depressed pores; lateral walls distinct, no marginal pores. Proximal to orifice is slightly raised peristome in form of a flattened, centrally joined costal collar. Autozooidal orifices slightly more than semicircular distally, shallowly V-shaped proximally, with curving round-edged condyles ( Fig. 21 B, C, E). Ooecia endozooidal. Fertile zooids distinguished primarily by shallower, more transversely elliptical orifices, with longer condyles ( Fig. 23 B, C, F). Frontal avicularia have been reported, but were absent in colonies from Oculina habitat . Remarks. The species was recently placed in a new family, Vitrimurellidae , and genus (Winston et al. 2014). The name previously used for Recent species was based on a very different fossil genus, Tremoschizodina Duvergier, 1921 . Species of Vitrimurella have a gymnocystal frontal shield with depressed pores and a pair of joined costae closing the proximal edge of the orifice, suggesting that their ancestry is from a Trypostega -like form. The perforated ooecia of fertile zooids are probably homologous with those of Trypostega , but they are shorter an flatter (see Fig. 23 B). Distribution. Reported from Florida, the Gulf of Mexico and West Africa.
