288 The Philippine Journal of Science 1913 



There are some specimens in the Bureau of Science collection 

 so broken that the columella, which is not visible in the entire 

 specimens, is visible nearer the base. 



Locality: West side of Aroroy Bay near Point Colorado, Mas- 

 bate, No. 588. 



Formation : Mio-Pliocene shale. 



This species has been found living at depths varying from 

 shallow water to 1,500 fathoms. 



The specimen shown on Plate XII, fig. 10, is also a Flabellum, 

 but it is too small and imperfect a specimen to be specifically 

 determined. 



0D0NT0CYATHUS Moseley 



Corallum with a fasicular columella and 3 crowns of pali, free 

 but with a minute scar of former attachment, in the form of a 

 deep saucer, with straight sloping sides and a broad fiat base 

 composed of fused radiating tuberculate spines which project 

 like the spokes of a wheel all round the base of the wall.

Odontoeyathus coloradus sp. nov. Plate XVIII, fig. 8. 



This species is essentially the same as 0. coronatus Moseley 

 save for one striking difference, the possession of 6, instead of 

 12, spines projecting from the base. This may be fortuitous, but 

 I am inclined to think not. The exterior wall is smooth and more 

 rounded in the Philippine form. Diameter of calix, 25 milli- 

 meters ; height, 15 millimeters. 



Locality: Point Colorado, Aroroy Bay, Masbate, No. 588. 



Formation: Miocene or Pliocene shale.

CYCLOSEBIS Edwards et Haime 



Free, disk shaped, circular; wall horizontal, naked with fine 

 granulated ribs, septa numerous, finely toothed on the upper edge, 

 the smaller ones intergrown on the inner edges with the larger. 

 Cretaceous, Tertiary, and Recent.

The specimen shown here is more perfect than the one figured 

 by Martin and has a hole in the center, which is entirely filled up 

 in the Javan form, otherwise the two are very nearly identical. 



I frequently have found this form on dead reefs along the 

 coasts, and it is my impression that the species is still liv-
