BRYOZOA OF THE PHILIPPINE REGION 



195 



Genus CAMPTOPLITES Harmer, 1923 



The peduncle of the avicularia is very long, flexible, larger than 

 the head. The proximal ends of the zooecia are not forked. 

 Genotype. — Camptoplites (Bugula) bicornis Busk, 1884. Recent. 



Genus KINETOSKIAS Danielssen, 1868 



The avicularia are pedunculate. Special method of bifurcation 

 (type 8 of Harmer). Two successive zooecia are separated by a 

 small uncalcified space. 



Genotype. — Kinetoskias smitti Danielssen, 1868. Recent.

 -Genus Bugula Oken, 1815 



A. Portion of branch of colony of B. sabatieri Calvet, 1900. B. Young 

 polypide with its extended tentacle. (A, B, after Calvet, 1900.) C. Mode of 

 branching of Bugula johnstoniae Gray, 1843, and of a large number of other 

 Bugulas. (After Harmer, 1923.) 



Genus HIMANTOZOUM Harmer, 1923 



Asymmetrical zooecia between which are intercalated one or more 

 of median symmetrical zooecia. The unstalked avicularia are at- 

 tached to the proximal ends of the zooecia, those of the lateral and 

 median rows more or less unlike. Special method of bifurcation 

 (type 8 of Harmer). No ovicell. The egg which is of large size, 

 develops in the body-cavity of the fertile zooecium. 



Genotype. — Himantozoum {Bugula) mirabilis Busk, 1884. Recent. 



Genus HALOPHILA (Gray, 1843) Levinsen, 1909 



The distal, broader, more or less symmetrical part of the zooecium 

 is separated from a nearly us long proximal, narrow, cylindrical part 

 by a constriction just distally to the distal wall. No avicularia. 

 No ovicell. The zoarium is biserial.
