BRYOZOA OF THE PHILIPPINE REGION 371 



The ovicell is not fissured, but it bears sometimes the "broad 

 mesial plate" indicated by MacGillivray, 1885. A simple small 

 tongue protects the orifice. (See text, fig 141.) 



All the authors speak of this species with enthusiasm because of 

 its beautiful red coral color. It is the calcite itself that is thus 

 colored; but the coloring material is so fine that it is not apparent 

 at the usual magnification (X85) of our tangential sections. The 

 dorsal is often deprived of vibices and the foramina are very incon- 

 stant. 



Biology. — Our specimens were in reproduction on February 7, 1908 

 (53 meters). This species is common in Australia; its discovery in 

 the Sea of China by Kirkpatrick, 1890, renders its presence very 

 probable in the intermediate areas. It is rare, nevertheless, in the 

 Philippines and it appears to live mainly in the Sulu Archipelago. 

 It has been noted only at shallow depths although we have found 

 two dead fragments at 439 meters but we are ignorant if they had 

 lived at this place. 



Complete colonies have never been figured by the author and 

 we are ignorant of the mode of fixation of the larvae.

SCHIZELLOZOON LUTEUM, new species 



Plate 49, figs. 1-6 



Description. — The zoarium is free, reticulated, yellow; the fenes- 

 trules are large, elongated, narrower than the trabeculae; the dorsal 

 is rugose or finely granulated and it bears transverse vibices very 

 irregularly arranged. The zooecia are distinct, elongated, separated 

 by a salient thread, hexagonal; the frontal is concave longitudinally, 

 smooth, cordiform; it bears an elliptical avicularium in which the 

 beak is turned towards the base and is very salient. The peristomice 

 is semicircular; it bears on its proximal lip a narrow pseudorimule; 

 the apertura hidden at the bottom of the peristomie bears a wide 

 shallow rimule. The ovicell is globular, salient, marginal; its frontal 

 is very fragile.
