Montlivaultia robusta sp. nov. Plate XVII, fig. 6. 



This specimen differs from the other two in being more robust 

 and having a larger base. 



Locality: San Miguel de Mayumo, Bulacan, Luzon. 



Formation: Limestone. 



All of these specimens are in outward appearance somewhat 

 like montlivaultias from the nummulitic of India, Lukkee, south- 

 ern Indus Range, and now in the British Museum. 



Montlivaultia cortada sp. nov. Plate XVIII, fig. 1. 



This species is very different from those already shown. It is 

 quite stumpy in appearance, but has all the generic characters 

 of Montlivaultia. It is pedunculate like the others shown. It 

 is a trifle wider at the top than it is long, the length being 2 

 centimeters. The base is small, and the sides make an angle of 

 about 75°. 



Locality : Beach at Caracaran, Batan Island, southeastern Lu- 

 zon, No. 2. 



Formation: Shale, probably Miocene. 



PATTALOPHYLUA d'Ach. 



Circular, short attachment, somewhat compressed laterally; 

 calyx elliptical; wall naked, covered with fine ribs; septa 

 numerous, serrate; columella lamellar-like or rudimentary, sur- 

 rounded by a manifold circle of long, ragged rods. Eocene. 

 (Zittel.) 



Pattalophyllia (?) bonita sp. nov. Plate XVIII, figs. 4 and 5. 



E. Osassco, Paleontographica italica, 8, 99, PI. I, figs. 3 and 3b. Mem. 

 Geol. Surv. India, ser. XIV, I, 2, PI. XX, figs. 1-3. 



Calix almost circular in plan, inverted shallow cone. Deep 

 sinus where columella should be. Height, 1 centimeter; diam- 

 eter of crown of calyx, 2.5 centimeters. 



This specimen resembles a form under the name Calyptraea 

 rugosa Noetling from the Miocene of Burma. The name Calyp- 

 traea, however, according to Zittel has already been used for 

 one of the Platypoda. 



It is also very similar to Trochocyathus nummiformis Duncan 

 from the Tertiary deposits of the Sind, India. The Philippine 

 form is deeper and has an elliptical hollow in the center, features 

 Avhich readily distinguish it from the Indian species. 



The closest resemblance, however, is to the figures in Osassco's
