SCHIZOPODKELLA FALCIPERA, new species 



Plate 10, Figures 2, 3; text Figure 15/, g 



Description. — The zoarium encrusts Cellepores. The zooecia are 



distinct, separated by a shallow fm-row, rectangular; the frontal is a 



tremocyst with small pores and is little convex. The aperture is 



placed eccentrically, rarely in the zooecial median axis. It is 



suborbicular with a rather deep proximal, triangular sinus. A small 



avicularium is placed at the side of the aperture; it is very thin and 



elongated. On the zoarial surface appears sporadically a large, 



very elongated somewhat falciform avicularium placed on a salient 



eminence .

Affinities. — The operculum is of the Schizopodrella type; the two 

 muscular attachments are removed from the border. 



This species resembles Schizopodrella longirostris Hincks, 1886, in 

 the often eccentric position of its aperture but differs from it in the 

 very different form of its zoarial avicularium which covers two or 

 three zooecia. Our specimen was in reproduction January 30, 1905.

SCHIZOPODRELLA PUNGENS, new species 



Plate 27, Figures 5-12; text Figure 15 a-c 



Description. — The zoarium encrusts shells or soft algae at their 

 bifurcation. It is uni or multi lamellar. The zooecia are distinct, 

 separated by a deep furrow, elongated, elliptical; the frontal is 

 convex and formed by a granular tremocyst with large pores. It is 

 ornamented with a more or less salient umbo placed on the median 

 axis in the vicinity of the apertura. The apertura is somewhat 

 elongated; the anter is large and semicircular; the poster is small, 

 distinct, with a broad rounded rimule; the peristome is thin, salient, 

 furnished with very short spines. The oral avicularium is thin, 

 triangular, with very salient beak; it is placed obliquely, adjacent to
