FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 401 



This seems to bo distinct from S. nitida, and is very evidently a 

 tropical species. It has occurred in the Philippine material but once, 

 in a collection marked " Tacloban Anchorage." It is known from other 

 tropical parts of the Pacific and elsewhere.

 This is a fine large species, with the chambers slightly convex and 

 smooth, the peripheral margin cai-inate, the apertural end extended 

 in an elliptical neck with a bifid tooth. 

 Length up to 2 mm. or more. 



Heron-Allen and Earland had this species from the Kerimba 

 Archipelago, off the southeastern coast of Africa. It has occurred 

 at four stations in the Philippine material, ranging in depth from 14 

 to 108 fathoms (25 to 198 meters), off Romblon; east of Masbate; 

 Malampaya Sound, Palawan Island, and off eastern Palawan.
