There are single, very typical, specimens from three stations — 

 D5154, Tawi Tawi Group, Sulu Archipelago ; D5162, Tawi Tawi Group, 

 Sulu Archipelago; and D5179, off Romblon. 



In these specimens the two last-formed chambers are almost op- 

 posite one another, and they have the fine striations characteristic 



of this species.

 There are single specimens from five stations. Tliese are China 

 Sea, ofi southern Luzon; between Burias and Luzon; between Samar 

 and Leyte; and in shallow water off Jolo Jolo. 



All these stations are in shallow water, ranging in depth from 18 

 to 61 fathoms (33 to 112 meters). 



Rhumbler records it from off Laysan Island. Many of the speci- 

 mens, according to variable information, are biioculme in character, 

 showmg that this is a species which is tending to become possibly 

 more related to Biloculina than Tnlocidina in its later characters.
