ules symmetrically placed on each side of the polypidian lamella. 

 Spines and reticulocellaria present. 



Harmer, 1926, has created the genus Lagarozoum for a recent species 

 of this genus. 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. 



Genotype. — Entomaria (Rhagasostoma) spinifera Canu, 1914. Re- 

 cent type, E. coronata new species. 



Range. — Eocene (Lutetian) — Recent. 



The known species of the genus follow. 



Entomaria coronata, new species Recent. 



Entomaria (Lagarazoum) profundum Harmer, 1926 Recent, Malay region. 



Entomaria (Rhagasostoma) spinifera Canu, 1914 Miocene (Helvetian). 



Entomaria (Semieschara) dutempleana d'Orbigny, 1852 Eocene (Lutetian). 



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 genotype.

Description.- — The zoarium is free and unilamellar or encrusting 

 nullipores. 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-
