Similar forms have been described and figured by Douville. 

 Plate XIII, fig. 5, shows a fragment of orbitoidal and coralline 

 limestone from Guila-Guila in Cebu, illustrating the charac- 

 teristic appearance of this rock and the abundance of the re- 

 mains therein. 



COELENTERATA 



LITHOPHYLLIACE^E 



MONTLIVATJLTIA Lamouroux 



Free, pedunculate, or attached by a wide base, cylindrical, 

 circular, or oval shaped; epitheca thick, but fragile and often 

 rubbed away ; septa numerous, wide, regularly toothed ; columella 

 lacking; cross plates strong and numerous. Common in the 

 Jura, not so well developed in the Trias, Cretaceous, and Tertiary. 

 (Zittel.) 



Montlivaultia bulacana sp. nov. Plate XVII, figs. 1 and 3. 



These two specimens though differing considerably in size 

 and shape are referred to the same species as it is thought 

 that the specimen shown in fig. 3 is somewhat distorted. The 

 specimens are 6 and 10 centimeters long and 3.5 and 4.5 centi- 

 meters wide, respectively. They were pedunculate. The septa? 

 are on the average 1 millimeter apart, and are apparently parallel 

 from the base to the edge of the calyx. At intervals, which 

 are not constant, there are lines perpendicular to the septa? 

 running around the calyx which may denote horizontal tabula?. 

 These forms roughly simulate Streptolasma from the Silurian, 

 but in the latter the septa? diverge fan-like from a median line. 



Locality: San Miguel de Mayumo, Bulacan, Luzon, No. 189. 



Formation: Limestone. 



One of these forms is not greatly unlike Turbinolia hippuriti- 

 formis Michelin, 30 which occurs in the cretaceous of France.
