HIPPOPORINA SQUAMOSA, new species 



Plate 37, figs. 8, 9 



Description. — The zoarium encrusts Orbitoides and small frag- 

 ments of shells. The zooecia are distinct, separated by a furrow, 

 small, elliptical, deformed laterally by one or two small oral avicularia; 

 the frontal is smooth and convex. The apertura is suborbicular; 

 two minute cardelles placed very low, separate the anter from the 

 poster; the latter is buried under a convex oral mucro. The ovicell 

 is embedded in the distal zooecium, globular, smooth, not closed by 

 the operculum. 



Measurements. —

lZa=0.05mm. \lz -0.25-0.30 mm. 



Affinities. — The ancestrula is a very small zooecium. The presence 

 of an oral mucro gives to the zooecia a very characteristic aspect for 

 they appear like small scales regularly imbricating in many rows 

 around the ancestrula. 



Biology. — All our specimens were dead. The geographic distri- 

 bution of this species is rather large for it has been dredged along 

 the two shores, western and eastern of the Sea of China.

HIPPOPORINA (?) VERRUCOSA, new species 



Plate 37, fig. 7 



Description. — The zoarium is unilamellar. The zooecia are dis- 

 tinct, separated by a furrow of little depth, large elongated, ellip- 

 tical; the frontal is somewhat convex and covered with small hollow 

 warts regularly arranged in quincunx. The apertura is placed at 

 the bottom of a peristomie formed by the thickening of the frontal;
