rOEAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 487 



spheric form were found with the outer annuli more or less broken 

 and thin, filled with numerous megalospheric young. These large 

 specimens were of tlie flattened form noted by Heron-Allen and 

 Earland from the Kerimba Archipelago. Specimens composed of 

 fused individuals are occasionally found also. The range of depths 

 is from 12 to 766 fathoms (22 to 1,400 meters), but two stations 

 being greater in depth than 500 fathoms (914 meters).

Heron-Allen and Earland note the identity of Dana's variety with 

 that of Brady .^^ 



It occurs at a few stations in shallow water with the outer annuli 

 containing megalospheric young.
