Heron-Allen and Earland, in their Kerimba paper, record this 

 species from Cebu in 45 to 120 fathoms (82 to 220 meters) and note 

 that it "is probably of vride distribution in tropical shallow seas." 



Brady describes the species from the following localities: Off 

 Ascension Island, 7 fathoms (13 meters); off Calpentyn, Ceylon, 2 

 fathoms (4 metei*s) ; and in shore sands from near Tamatave, Mada- 

 gascar; and near Port Elizabeth, Algoa Bay. 



Millett records it from the Malay region as very rare, having but 

 a single specimen from but one station. 



Chapman records it from Funafuti and Heron-Allen and Earland 

 from the Kerimba Archipelago. 



iUl the Philippine material is of the short form wliich Heron-Allen 

 and Earland mention in their paper, none of the longer form being 

 present. 



There are also specimens from the nine stations which have the 

 quinqueloculine form and very thin reticulate ornamentation, like the 

 triloculine forms, and may be simply an early quinqueloculine stage. 



This species ranges in depth from very shallow water to 318 fathoms 

 (582 meters), representing the following localities: Binang Pool, 

 Subin Bay; Tara Island; Sulu region, off Jolo, off Tawi Tawi, near 

 Basilan; China Sea, off southern Luzon; and between Burias and 

 Luzon.
