BRYOZOA OF THE PHILIPPINE REGION 275 



Genotype. — Cosciniopsis coelatus Canu and Bassler, 1927. Recent. 



The operculum is absolutely identical with that of Galeopsis and 

 there is therefore no anatomical difference. But all the peristomial 

 apparatus having disappeared, the operculum closes the ovicell in 

 order to facilitate the passage of the eggs. In Galeopsis the oper- 

 culum has the same function but closes the spiramen. Four species 

 are referred to this genus. 



Cosciniopsis vestita Hincks, 1885 Recent. 



Cosciniopsis coelatus Canu and Bassler, 1927 Recent. 



Cosciniopsis auslralis Waters, 1889 Recent. 



Cosciniopsis (Emballotheca) laticapitata Canu and Bassler, 1920 Eocene.

We have not found this species in the Philippines. Examination 

 of the figures shows that it differs from Galeopsis only in the absence 

 of a spiramen.

Description. — The zoarium encrusts nullipores or other bryozoa; 

 the ectocyst is light colored or golden. The zooecia are distinct, 

 separated by a deep furrow, very large, elongated, utricular; the 

 frontal is convex and formed of a trcmocyst with very numerous 

 small pores. The aperture is suborbiculate with two cardelles 

 placed low; the peristome is wide and smooth. The ovicell is 

 enormous, globular, embedded in the distal zooecium, closed by the 

 operculum. The orifice of the ovicelled zooecia is larger and trans- 

 verse. The operculum is embossed with concentric arabesques.
