In the Malay Archipelago this planospiral form occurs at 

 several Stations, and is moderately abundant. The examples 

 exhibit considerable diversity of form and texture, and often closely 

 resemble Hastigerina pelagica.

This form is but poorly represented in the Malay Archipelago ; 

 the examples are few and insignificant. It occurs at a small 

 number of Stations in both Areas.
