. m a v. Fig. 8. A. Menipea zelandica St. 935, New Zealand. The three marginal series of zooecia, separated from the rest by eau de javelle, in basal view. Opesiae and rootlet-chambers shown with dotted line. B. M. vectifera Harmer. St. 929, New Zealand. Large basal avicularium at intercalation of new series of zooecia with underlying zooecia outlined. basal avicularium, basal wall of zooecium of inner series, internal avicularium, lateral wall of inner series, marginal avicularium, marginal zooecium, rootlet-chamber. Remarks. This species resembles Menipea roborata (Hincks), which is also bilaminate, in the shape of the zooecia and of their cryptocyst and oral shelf, in the spines, and the rootlets. The frontal avicularia are unpaired and larger; the rootlet chambers are larger and the zooecia are distinctly larger. The branches show less terminal widening and are frequently curved, cf. the straight or concave margins of the branches of M. roborata in Plate V, fig. 4 and the curved branches with one margin convex and the other concave to the right of the colony of M. zelandica, Plate V, fig. 3.
