FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 355 



and at equidistant points on the periphery. A study of the young 

 and the development of older specimens of the same type from this 

 localit}'" show it to be a Calcarina. The name haadatus may be used 

 probably to distinguish this species, although as to the generic 

 portion it is very questionable as to its clearness and therefore its 

 availability. 



In its development it is seen that this species of Calcarina has a 

 considerable development of supplementary skeleton, which, as in 

 C. hispida, hides most of the earlier portion of the test. 



Specimens referred to in this species were found in the Philippine 

 collections from Jolo Jolo, Sulu Archipelago, vicinity of Siasi; Tawi 

 Tawi Group; off Romblon; off eastern Pana}^; between Burias and 

 Luzon; Pacific Ocean; east coast of Mindanao; Gulf of Davao; China 

 Sea, off southern Luzon; Palawan Passage; Marinduque Island and 

 vicinity; east coast of Luzon; north of Tawi Tawi; and Sibuko Bay, 

 Borneo. 



These are mostly in the southern portion of the Archipelago in 

 shallow, warm water. 



This species should be carefully distinguished and its occurrence 

 recorded that more may be known of its actual distribution.
