BRYOZOA OF THE PHILIPPINE REGION 489 



Affinities. — This superb species is very well characterized by the 

 crescent-shaped cushion around each aperture. There are two very 

 small pores above each aperture (distally); moreover similar small 

 pores are arranged between each avicularium and the neighboring 

 apertures. 



The figured specimen is the only one found but it is a magnificent 

 example.

CONESCHAUELLINA GRANDIPOROSA, new species 



Plate 68, figs. G, 7 



Description. — The zoarium is conical; the height is 4 mm. The 



apex is very obtuse. The zooecia are arranged in very regular radial 



rows separated by rows of alternate, orbicular avicularia. The 



aperture is large, elongated, with a wide, distal, ogival sinus. The 



base is concave, bordered by zooecia and garnished by small irregular 



pores.

Affinities. — This species is very well characterized by the special 

 form of its aperture. The figured specimen is the only one that has 

 been found but it is a very beautiful example.

CONESCHARELLINA ELONGATA. new species 



Plate 69, figs. 1-9 



Description. — The zoarium is conical, very long, much longer than 

 wide. The zooecia are arranged in quincunx, in radial or in oblique 

 rows; the interzooecial avicularia are large, elongated, oval, with 

 pivot. The aperture is orbicular or transverse with a very wide 

 distal sinus. The peristome is thin and very little salient; the proxi- 

 mal pore is large, round, or arched into a transverse cleft; the base is 

 entire, orbicular, with a large cancellated center; the pores are polyg- 

 onal and sometimes some of them are closed by a perforated calcare- 

 ous pellicle. 



Measurements. — 

 Aperture ffta = 0.12-0.14 mm. Aperture \ha = 0.\2 mm. 



(orbicular)Ua = 0.12-0.14 mm. (transverse)ua = 0.14 mm. 



Variations. — This species is very variable. The length of the 

 zoarium varies from 3 to 10 millimeters and its diameter from 2 to
