Genus ALLANTOPORA Lang, 1914 



We already knew two tropical species of this genus discovered by 

 Lang in the Cretaceous, and in addition to these are the following: 

 Allantopora translucens Harmer, 1926, Malay region. 

 Allantopora curta, new species, Philippines. 



ALLANTOPORA CURTA, new species 



Plate 2, fig. 7 



Description. — The zoarium encrusts bryozoa, in uniserial, ramified 

 series. The zooecia are elongated, elliptical, ornamented by a short 

 smooth, convex, narrow gymnocyst. The mural rim is thick, rounded ; 

 the opesium is elliptic or somewhat pyriform. The ovicell is hyper- 

 stomial, narrower than the zooecium. 



Measurements . — 



~ . \~ho = 0.35 mm. „ jLz = 0.65-0.70 mm. 



Opesium^, „ _ Zooeciumi, 



llo = 0.25 mm. lis = 0.40 mm. 



Affinities. — Our specimens being dead and dried up, we can not 



observe if they bore spines. The species differs from Allantopora 



translucens Harmer, 1926 in its very short and rectilinear gymnocyst.

Genus MEMBRANIPORIDRA Canu and Bassler, 1917 



MEMBRANIPORIDRA TUBEROSA, new species 



Plate 8, fig. 3 



Description. — The zoarium encrusts orbitoid foraminifera. The 

 zooecia are distinct, separated by a deep furrow, oval, large, little 

 elongated; the mural rim is thin, salient, but much enlarged at the 

 base into a true cryptocyst, granulated; the gymnocyst is very short, 

 convex, smooth. The opesium is oval, large, anterior. The ovicell 

 is convex, smooth, covered by an incomplete pleurocyst, surrounding
