BRYOZOA OF THE PHILIPPINE REGION 319 



Occurrence.— D. 4807. Cape Tsiuka, Sea of Japan; 41° 36' 12" N.; 

 140° 36' E. 

 Holotype.— Cat. No. 8081, U.S.N.M. 



SCHIZOPORELLA PRODITOR, new species 



Plate 35, fig. 6 



Description. — The zoarium is free and unilamellar. The zooecia 

 are distinct, separated by a deep furrow, elongated, rectangular; the 

 frontal is convex and perforated with large tremopores. The aper- 

 tura is suborbicular, somewhat elongated; it is formed of a semi- 

 circular anter and of a very broad rimule. At the side of the aper- 

 tura there is a long slender avicularium with a very pointed beak 

 turned towards the base and attached to the distal zooecium.

Biology. — This species is very well characterized by its oral avicu- 

 larium attached to the distal zooecium. Although incomplete this 

 small fragment appeared interesting enough for description; it reveals 

 once more the biologic unity of a bryozoan colony. It is absolutely 

 false that each zooecium is independent for all the zooecia lived one 

 for the other to the profit of the entire zoarium. They are obedient 

 to an instinctive law of which the ancestrula arising from the larva 

 is the necessary origin.

Subfamily Hippoporae Canu and Bassler, 1917 



Genus HIPPOPORINA Neviani, 1895 



HIPPOPORINA GRANIFERA, new species 



Plate 35, fig. 10 



Description. — The zoarium encrusts entirely small fragments of 

 shells. The zooecia are distinct, separated by a little elongated 

 furrow, deformed by a lateral avicularium; the frontal is very 

 convex and bears large granulations. The apertura is small, elon- 

 gated; the anter is pyriform; the poster is enlarged in the proximal 

 portion. The ovicell is globular, placed on the distal zooecium, not 

 closed by the operculum.

Affinities. — This species is very well characterized by its large 

 frontal granulations. The figured zoarium forms a small fusiform 

 mass. Our specimens were dead.
