BRYOZOA OF THE PHILIPPINE REGION 193 



VII. A normal zooecium emits distally two separated or united 

 zooecia (Maplestonia in Scrupocellariidae). 



Genus BUGULA Oken, 1815 



The operculum is wanting. The avicularia are capitate, peduncu- 

 late, freely movable and situated on the lateral zooecia. The 

 radical fibers issue both from the frontal, basal, and lateral aspects 

 of the colony. There is a row of distal septulae. The zoaria are 

 bi-multiserial. 13-15 tentacles. 



Genotype. — Bugula (Cellularia) neritina Linnaeus, 1758. Recent. 



Genus CAULIBUGULA Verrill, 1900 

 StirparieMa Harmer, 1925, Stirparia Goldstein, 1880, preoccupied 



The stem is jointed and consists of a row of long narrow segments. 

 The zoaria are biserial. 



Genotype. — Caulibugula {Bugula) armata Verrill, 1900. Recent. 



Genus BUGULARIA Levinsen, 1909 



The avicularia are sessile and placed on the proximal gymnocyst 

 of each zooecium. 



Genotype. — Bugularia (Carbasea) dissimilis Busk, 1852. Recent. 



Genus WATERSIA Levinsen, 1909 



No avicularia. The radical fibers issue everywhere from the 

 covering membrane of the frontal surface in the two layered colony. 

 Genotype. — Watersia (Flustra) militaris Waters, 1887. Recent. 



Genus DENDROBEANIA Levinsen, 1909 



The freely movable avicularia are situated upon all the zooecia. 

 The radical fibers issue from the second (more seldom also from the 

 first) septula of the marginal zooecia. 18-21 tentacles. 



Genotype. — Dendrobeania (Flustra) murrayana Johnston, 1847. 

 Recent. 



Genus EUOPLOZOUM Harmer, 1923 



The zooecia are large and obliquely alternating. Special method 

 of bifurcation (type 6 of Harmer). The zoarium is biserial. 



Genotype. — Euoplozoum (Cellularia) cirrata Busk, 1884. Recent.
