BRYOZOA OF THE PHILIPPINE REGION 519 



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

 of the orifices. However, among the fossil forms there are some 

 species rather close to this one, notably Proboscina cornucopiae 

 D'Orbigny, 1847 of the French Cretaceous. The persistance of the 

 Cretaceous forms in the present equatorial zone is a constant phenom- 

 enon. 



Occurrence— D. 5137. Jolo Light, Jolo; 6° 04' 25" N.; 120° 58' 

 30" E.; 20 fathoms, S. Sh. 



Holotype.— Cat. No. 8327, U.S.N.M. 



Forma FILISPARSA D'Orbigny, 1853 



FILISPARSA BUGOSA, new species 



Plate 76, figs. 7-9 



Description. — The zoarium is free, formed of three longitudinal 

 rows of tubes, narrow, a little compressed, bifurcated. The tubes 

 are arranged only on the anterior face; they are little distinct and 

 much wrinkled transversely. The orifice is orbicular; the peristome 

 is thin and the peristomie very salient and erect. The posterior face 

 of the zoarium is also covered with large transverse wrinkles. 



Measurements. — Diameter of peristome, 0.28-0.30 mm.; distance 

 of orifices, 1.12-1.84; and width of branches, 0.50-0.60. 



Affinities. — This is a beautiful and quite vigorous species which 

 appears to us interesting enough to figure in spite of the absence of 

 the ovicell. 



Occurrence— D. 5478. Tacbuc Point, Leyte; 10° 46' 24" N.; 125° 

 16' 30" E.; 57 fathoms; Sh. 



Cotypes.— Cat. No. 8328, U.S.N.M. 



FILISPARSA ELEGANS, new species 



Plate 76, fig. 3 



Description. — The zoarium is free, bifurcated; the branches are 

 compressed, broad and bear cellules only on a single side. The 

 tubes are visible; the peristome is salient, arched; the peristomes are 

 thin, arranged in irregular quincunx. 



Measurements. — Diameter of peristome, 0.24-0.25 mm.; and width 

 of branches 0.80. 



Affinities. — This is an elegant and robust species quite easy of 

 determination. It differs from Filisparsa rugosa in its more closely 

 arranged peristomes and in the absence of transverse wrinkles. 



Occurrence.— D. 4807. Cape Tsiuka, Sea of Japan; 41° 36' 12" N.; 

 140° 36' E. 



Holotype.— Cut. No. 8415, U.S.N.M.
