BRYOZOA OF THE PHILIPPINE REGION 345 



Occurrence. — D. 5217. Anima Sola Island, between Burias and 

 Luzon; 13° 20' N.; 123° 14' 15" E.; 105 fathoms; crs.gy.S.; 17.2° C. 

 Cotypes.—C&t. No. 8125, U.S.N.M. 



SMITTINA TRISPINOSA, var. GRANOSA, new variety 



Plate 42, figs. 1, 2 



Description. — The apertura is orbicular or oval and finely denticu- 

 lated; the peristome is thin, salient, complete, with two distal spines. 

 The lyrula is wide, the two cardelles are triangular and placed a little 

 higher. The frontal is covered with scattered granules and surrounded 

 by small areolar pores. The large avicularia are attached to the side 

 of the apertura and arranged on the zooecial border; they are largely 

 spatulate. The small avicularia are elliptical or triangular, they are 

 irregularly placed on the frontal to the number of 2 or 3 ; the beak is 

 turned toward the base and sometimes toward the top. The ovicell 

 is globular, trincrvate, and measures 0.25 mm. in diameter. 



Measurements.- — 



1 lZa=0.10mm. \lz -0.40-0.60 mm. 



Affinities. — In its dimensions and its large avicularia this variety 

 much resembles the variety spatulata Smitt, 1872, but it differs in 

 the nature of its more granular frontal, in its peristome without 

 pseudorimulc and in the presence of small elliptical avicularia. It has 

 been observed only in a single locality. Our specimens are unilam- 

 ellar; they were dead. 



Occurrence— D. 5478. Tacbuc Point, Leyte; 10° 46' 24" N.;

SMITTINA TRISPINOSA var. APPLICATA, new variety 



Plate 42, fig. 3 



Description. — The peristomice is orbicular or oval without proximal 

 pseudorimulc. The lyrula is wide and little salient. The ovicell 

 is small and measures 0.20-0.25 mm. in diameter. At the side of the 

 apertura and attached to the peristome there is frequently a small 

 ascendant, triangular, avicularium, in which the pointed beak is 

 turned toward the top. 



Measurements. — 



Peristomice!^ =°- 09 mm ' Zooeeiaff 2 ^i* 5 " - 45 """' 



lip -0.08 mm. Uz=0.2o mm. 



Affinities. — This variety differs from the variety japonica Ortmann, 



1890, in its much smaller avicularium which is not arranged on the 



frontal below the apertura. Our specimens encrust shells; they were 



dead. It differs from the type of the species in the constancy in the 



position of the avicularia.
