BRYOZOA OF THE PHILIPPINE REGION

Genotype. — Halophila johnstoniae Gray, 1843. Recent. 



Harmer 1923, thinks that Halophila is perhaps synonymous with 

 Bugula. Himantozoum and Halophila form a special group in the 

 family. We are ignorant of the larva and their position is not 

 therefore definite. 



Family SCRUPOCELLARIIDAE Levinsen, 1909 



The larva is wider than high; the terminal bud is small; the 

 vibratile plume is subproximal; the corona is sinuous. The ramifica-

A-F. Camploplities bicornis Bvisk, 1884. A. Branch, natural size. B. View 

 of frontal of a branch, X 13. C. Dorsal view, X 13. D. Two avicularia and 

 radical tube, X25. E. Smaller avicularium arising close below the opesium, X25. 

 F. Larger avicularium showing the digitiform process, X25. (After Busk, 1884.) 



tion of the branches is occasioned by the formation of a supplementary 

 median zooecium. The ovary is distal and a large egg passes into the 

 ovicell. The zoarium is free, erect, unilamellar, radicellate and gener- 

 ally articulated. The zooecia have an opesium and a gymnocyst 

 and bear heterozooecia. Typically there are one or two frontal 

 avicularia, a lateral superior avicularium, distal spines, a proximal 

 radicular dietella, a dorsal vibraculum (basal of Harmer and Levinsen) 

 and a scutum on the opesium. 



The list of genera in this family is as follows:

 Cauda Lamouroux, 1816; Caberea Lamouroux, 1816 (Selbia Gray,
