FIG. 6. — Collarina denticulata Harmelin, n. sp.: A, non-ovicelled autozooids with paired avicularia, three spines and large costate shield with prominent medial crest running into the apertural bar; B, ovicelled zooids, note the shape of the orifices and the poorly prominent ooecia built by the autozooid distal to the maternal zooid; C, distal part of a non-ovicelled zooid showing the particular shape of the orifice, the spines with conical base and the paired avicularia with narrow rostrum; D, oblique view of the distal part of a non-ovicelled zooid showing the apertural bar, the sub-pedunculate avicularia and the spine bases; E, oblique view of the proximal part of an autozooid showing the pedunculate marginal pelmatidia and the poorly developed gymnocyst; F, lateral portion of the costate shield with oblong intercostal lacunae; G, autozooid with adventitious avicularia with nested cystids.
