larium is very salient, transverse, the beak turned toward the 

 median axis of the zooecium. All of our specimens were dead. 



Schizoporella nodulifera MacGillivray, 1890, and Schizoporella 

 speciosa MacGillivray, 1890, belong to this same group, Embal- 

 lotheca.

Structure. — In the vicinity of the aperture, there is a very small, 

 very thin, oblique avicularium with the beak directed toward the 

 base. The operculum of the ovicelled zooecia is larger than the 

 others. The frontal is very finely granulated and is perforated by 

 a multitude of very small tremopores which appear more distinctly 

 in tangential sections. The place of the condyles of the apertura is 

 indicated on the opercula by two small lueidae. 



On the figure of Hincks, 1884, the rimule of the apertura is sub- 

 triangular; it is clearly concave on our specimens. 



Biology. — Our living specimens from Anima Sola were ovicelled on 

 April 22, 1908.

Description. — The zoarium is unilamellar; it encrusts nullipores. 

 The zooecia are distinct, separated by a furrow, elongated, ovoid; 

 the frontal is convex, finely granulose and covered by small tremo- 

 pores. The apertura is orbicular with two small cardelles separating
