BRYOZOA OF THE PHILIPPINE REGION 561 



LICHENOPORA LAMELLOSA, new species 



Plate 89, figs. 5, 6 



Description. — The zoarium is free, orbicular, much elevated and 

 almost as high as broad; the base is concave. The fascicles are 

 formed of salient lamellae and are radial, uniserial. The cancelli are 

 irregular, polygonal, as large as the apertures. 



Measurements. — Diameter of colony, 3 mm.; width of lamella and 

 of tubes, 0.10 mm. 



Affinities. — The figured specimen only has been found. It resem- 

 bles certain fossil species from the Cretaceous and the Tertiary which 

 the paleontologists have called Defrancia. The great zoarial height 

 depends probably on the form of the substratum and in order to 

 determine the true character of this species it would be necessary to 

 have many specimens. We have figured it, however, in order to 

 prove again the absolute necessity for paleontologists to know the 

 recent tropical fauna. 



Occurrence. — D. 5579. Sibutu Island, Darvel Bay, Borneo; 4° 54' 

 15" N.j 119° 9' 52" E.; 175 fathoms; fine S. Co.; 13° C. 



Holotype.— Cat. No. 8390, U.S.N.M. 



LICHENOPORA (DOMOPORA) STRICTOLAMELLOSA, new species 



Plate 89, figs. 8, 9 



Description. — The zoarium is free, formed of superposed sub- 

 colonies which are high and surrounded by a narrow marginal lamina; 

 the fascicles are salient, narrow, much scattered, biserial. The peri- 

 stomes are thin, nonsalient. The cancelli are rather large, polygonal, 

 with little thickened walls. The ovicell is large, central. 



Measurements. — Diameter of zoarium, 2.5 mm.; height of zoarium, 

 3.5 mm. 



Affinities. — The figured specimen only has been found and it is 

 incomplete. This species differs from Lichenopora stellata Reuss, 

 1847, a fossil species assigned also to Domopora, in its much narrower 

 and scattered fascicles. The nature of the tubes does not appear to 

 be that of Lichenopora, but we have not been able to make the neces- 

 sary thin sections. 



Occurrence. — D. 5162. Tinagta Island, Tawi Tawi Group; 5° 10' N.; 

 119° 47' 30" E.; 230 fathoms; S. brk., Sh. crs.; 11.0° C. 



Holotype.— €at. No. 8391, U.S.N.M.
