a chitinous band as in Petrdliella and bears two long, thick, lateral 

 attachments little distant from the border. 



Biology. — The species was in reproduction and fixation on February 

 15, 1908 (14-47 meters). Our specimens were living. The large 

 dimensions of this species permit it to absorb relatively large organ- 

 isms. Thus we have found in the cells, diatoms, spicules, radiolaria 

 and small foraminifera.

COLEOPORA ERINACEA, new species 



Plate 19, figs. 5-8 



Description. — The zoarium encrusts nullipores. The zooecia are 

 distinct, separated by a deep furrow, very large, elongated, elliptical 

 or oval, swollen; the frontal is very convex, covered with large round 

 scattered pores arranged in quincunx; each pore is surrounded by a 

 salient peristome and bears distally a small triangular very salient 

 galea. The apertura is hidden by a peristomie in which the operculum 

 operates; the peristomice is suborbicular. The ectocyst is hidden by 

 the frontal; it is of a light color but sometimes green or very pale rose.

Structure. — The ensemble of the small helmetlike protruberanees 

 (galea) of the pores gives a spiny aspect to each of the zooecia. This 

 ornamentation disappears easily, for it is very fragile and the large 

 tremopores are more visible. Almost all our specimens were living, 

 but we have not found the ovicell. 



The frontal shows in tangential section a close network of very 

 large tremopores with thick walls, an arrangement very different
