He classed it in the Aspidostomatidae, but the ovicell being endotoichal and not hyperstomial and placed on the distal zooecium, we prefer to place it in the Setosellidae, the larva being unknown.

Entomaria coronata, new species Recent. Entomaria (Lagarazoum) profundum Harmer, 1926 Recent, Malay region. Entomaria (Rhagasostoma) spinifera Canu, 1914 Miocene (Helvetian).

Canu, 1921,7 chose Rhagasostoma spinifera Canu 1914, as the type of the genus but now that we know a recent species, it is preferable to at least consider it as a second Fig. 43.—Genus Lagarozoum Harmer, 1926 A-C.

The zooecia are distinct, separated by a furrow, large, elliptical, elongated; the mural rim is thin, distally salient, attenuated laterally, smooth; the cryptocyst is shallow, oblique toward the aperture, finely granulated. The aperture is semielliptical trans- verse; it bears on the proximal border a short convex polypidian la- ' Canu in list given by Duvergier, Bryozoaires du Neogene de l'Aquitaine, Soc.
