FIGURE 4 in Bryozoans from Rio Grande do Sul Continental Shelf, Southern Brazil

FIGURE 4. Cellaria riograndensis sp. nov. (A, D: MNRJ-1192; B: MNRJ-1170; C: MNRJ-1191). A, distal part of an internode showing an incipient branch bifurcation; B, close-up of autozooids and a vicarious avicularium; C, part of internode showing ovicellate zooids with ooecial apertures; a vicarious avicularium is also shown; D, close-up of autozooids and a vicarious avicularium; note the difference in shape of the combined opesial-rostral foramen compared with that in B, perhaps the consequence of erosion. Scalebars: A, 500 µm; B–D, 100 µm.
