This form is found at two Stations in considerable numbers, 

 but the examples are small and weak. They vary in the direction 

 of R. orbicularis, but no typical specimens of this latter form have 

 been observed.

This fine species is abundant, large and typical, at Stations 14 



and 17. 



Schroeter records it from Tramjuebar, and states that the 

 examples are the size of poppy-seeds. Brady * writes, " No well- 

 marked specimens of Rotalia Schroeteriana have been met with in 

 the ' Challenger ' dredgings. Though somewhat local in distribu- 

 tion, it is by no means rare amongst the islands of the Eastern 

 Archipelago, at depths of less than 50 or 60 fathoms." The 

 • Gazelle ' Stations are West Australia, Amboyna and New Guinea,
