Family ASPIDOSTOMATIDAE Jullien, 1888 



155 



We have discussed this family and its genera in our works of 1920 

 and 1923. Certain genera there placed here are now referred else- 

 where as will be noted by consulting our alphabetical generic list. 

 Following is our present classification. 



I. Aspidostoma Hincks, 1881, Monoporella Hincks, 1881, Macro- 

 pora MacGillivray, 1895, Rhagasostoma Koschinsky, 1885 (Levinsen, 

 1907, emend). 



II. (Uncertain) Foraminella Levinsen, 1907; Odontionella Canu and 

 Bassler, 1917; Megapora Hincks, 1877; Mollia Lamouroux, 1821. 



Fig. 38. — Genus Mollia Lamouroux, 1821 



A-D. Mollia patellaria Moll, 1803. A. Incrusting specimen, X25, showing 

 closed cells. B. Ordinary and ovicelled zooecia, X50. The cryptocyst is 

 covered by the ectocyst. The ovicell is hyperstomial. C. Dorsal side of 

 zooecia. From the base there are thrown out a number of radicular fibers by 

 which the colony is fastened to stones, sponges, etc. D. Radicular fibers seen 

 in profile. (After Waters, 1879.) 



Genus MOLLIA Lamouroux, 1821 



The ovicell is hyperstomial and closed by the operculum. The 

 zooecia are disjointed and united by cylindrical junctures. The 

 opesium is trifoliated. The opercular valve is supported on the two 

 lateral teeth but does not touch the distal portion of the mural rim. 

 No spines, no avicularium. The zoarium is unilamellar. No die- 

 tellae. 



Genotype. — Mollia (Eschara) patellaria Moll, 1803. Recent. 



Genus MONOPORELLA Hincks, 1881 



The ovicell is hyperstomial, closed by the operculum, entirely 

 buried in the distal zooecium, surrounded with costules or with a 

 fringe. The apertura bears proximally two, very small, lateral inden- 

 tations. Two small opesiules perforate the porous cryptocyst. The
