BRYOZOA OF THE PHILIPPINE REGION 487 



Affinities. — The apertures are arranged laterally on the radial crest 

 as in Conescharallina catella but the present species differs in its trans- 

 verse (and not elongated) zoarium in its larger and less numerous 

 apertures, and in the scattered pores of the base. 



Occurrence.— D. 5670. Chenoki Point, Macassar Strait; 1° 19' 00" 

 S.; 118° 43' 00" E.; 1,181 fathoms; gy. M.; 2.8° C.

CONESCHARELLINA DELICATULA, new species 



Plate 65, figs. 5-8 



Description. — The zoarium is conical, small, somewhat higher than 

 wide; the apex is sharp. The zooecia are arranged in radial rows and 

 form wide costules very little salient. The aperture is located at the 

 bottom of a small elliptical area; it is suborbicular with a small, 

 distal, rounded sinus. The avicularia are small, elliptical, with pivot, 

 widely scattered, alternate. The base is a little convex, entire; it 

 bears irregular perforations and avicularia with pivot widely spaced. 



Measurements. — 



Aperture!^ = ™] mm " Zoarium/* = 2 - 00 mm ' 



lZa = 0.07mm. Id =1.50 mm. 



Affinities. — The meridianal section shows 4 longitudinal rows of 



small internal zooecia; the exterior cells with polypides are relatively 



very long. 



This delicate little species differs from Conescharellina jucunda in 



the presence of scarcely visible radial costules, in scattered alternating 



interzooecial avicularia and in its more or less elongated zoarium. 



Occurrence. — 



D. 5134. Balukbaluk Island, Sum Archipelago; 60° 44' 45" N.; 



121° 48' E.; 25 fathoms; fine S. 



D. 5135. Jolo Light, Jolo; 6° 11' 50" N.; 121° 08' 20" E.; 



161 fathoms; fine co. S.; 11.5° C. (common).

CONESCHARELLINA PARVIPOROSA, new species 



Plate 66, figs. 5-7 



Description. — The zoarium is conical, more elevated than wide; 

 the apex is pointed. The zooecia are arranged in radial rows. The 

 aperture is small, orbicular or somewhat elliptical; the peristome is a 

 little salient; the proximal pore is adjacent to a peristome. The 

 avicularia are small, orbicular, with pivot, scattered, alternating in 

 each radial row. The external walls are very finely granulose. The 

 base is oval or orbicular, entire, convex, ornamented with small 

 poriform avicularia widely spaced and with pivot.
