BRYOZOA OF THE PHILIPPINE REGION 163 



large, elliptical, broad and a little elongated. The mural rim is 



very thick, convex, smooth, very salient distally, attenuated laterally; 



the cryptocyst is shallow, oblique towards the aperture, covered with 



small tremopores. The aperture is small, semielliptical, transverse; 



it bears inferiorily a very short polypidian lamella. The ovicell is 



convex, transverse, porous and granular. Straight reticulocellaria 



occur.

Structure. — Our specimens were dead and deprived of the ectocyst. 

 A single specimen was ovicelled; it bears three ovicells one of which 

 is complete, a second has a frontal fissure while the third is broken 

 and shows its endotoichal structure. The communication of the 

 ovicell with the zooecium appears to be made by a longitudinal slit 

 above the distal wall of the zooecium. The structure which Mac- 

 Gillivray, 1895, has taken for an ovicell in Crateropora patula is a 

 monstrosity analogous to that which appears in our figured speci- 

 men. We are ignorant of the mode of fixation. 



Aijinities. — Harmer, 1926, figured only the transverse zooecia (as 

 at the top of our figure) but in his descrpition he says "zooecia 

 usually wider than long" which proves that long zooecia may be 

 present. On our specimens the cells are somewhat longer than 

 wide. In spite of this difference we do not believe our determina- 

 tion is incorrect. 



Harmer was able to study the operculum, the mandible and to 

 show the position of the opercular and opesiular muscles.

The ovicell is endotoichal and placed at the distal extremity of 

 the zooecia; it is opened by a frontal pore on the same plane as the 

 operculum; it is ornamented with two lateral fissures. The aperture 

 is closed by an operculum with double sclerite; it bears inferiorily a 

 short polypidian lamella which is elevated and convex. Two opesi-
