BRYOZOA OF THE PHILIPPINE REGION 241 



FIGULARIA JUCUNDA, new, pecies 



Plate 22, fig. 3 



Description. — The zoarium encrusts nullipores; it separates easily 

 from its substratum. The zooeeia are distinct, separated by a 

 furrow, a little elongated, elliptical, swollen; the surface is convex 

 and bears a subcircular cribriform area surrounded by a circle of 

 pores with salient peristomes. The apertura is semielliptical, trans- 

 verse, with a very concave proximal border. The ovicell is very 

 large, globular, carinatcd, with two small transverse slits symmet- 

 rically arranged on each side of the median carina. The aperture of 

 the ovicelled zooeeia is larger; the operculum closes the ovicell. 



Muisurements. — 



Zooeeia \Lz = 0.60 mm. . jha = 0.12 mm. 



(ovicelled)}^ = 0.50 mm. po G \la = 0.20 mm. 



Zooeeia (1,2 = 0.50 mm. , lha = 0.12 mm. 



(ordinary) [£2 = 0.36-0.40 mm. pel G [la = 0.14 mm. 



Structure. — The structure of this species is identical with that 

 of FigvJariajissurata; its ectocyst is placed below the costules. The 

 exterior decoration is most charming and worthy of inspiring the 

 artistic decorator. 



The operculum of the ordinary zooeeia is orbicular and surrounded 

 by a thick sclerite. The operculum of the ovicelled zooeeia is formed 

 like a bell like that of Figvlaria cliihridiata Waters, 1887. The 

 operculum does not bear any trace of muscular attachments. 



Biology. — Our specimens were in reproduction in February, 1908.

 Holotype.—C&t. No. 7994, U.S.N.M. 



Genus BARROISINA Jullien, 1886 



The ovicell is hyperstomial. The frontal is costulated. The 

 apertura bears a proximal rimule. The avicularia are more or less 

 constant and dispersed between the zooeeia. 



Genotype. — Semiescharipora elegantula Beissel, 1865. Cretaceous. 

 Lang, 1917, considered the genotype as synonymous with Ccllcjmnt 

 cornuta Hagenow, 1839, and placed it in Pliophloea Gabb and Horn, 

 1862. The second species cited by Jullien is Lepralia haueri Reuss, 

 1S74 from t he Miocene.
