This species is likewise rare in the Malay Archipelago, but it 

 is found in both Areas, and the examples are well developed.

In treating of Bigcnerina (Siphogenerina) Schlumbcrgcrii men- 

 tion was made of the difficulty of assigning to the various forms of 

 Sipliogenerina their correct position in the classification of the 

 foraminifera ; whether columellaris would be more at home amongst 

 the Sagrina^ or the Bigcnerina?,, is still a matter of opinion. 



The recent discovery by Prof. Silvestri* of characteristic 

 specimens of Fleurostomella brevis having the contorted internal 

 tube, is of great interest in its bearing on this question. 



In the Malay Archipelago the number of examples is small 

 and the species seems to be confined to Area 1. There are, how- 

 ever, specimens of both the microspheric and megalospheric forms, 

 which are well differentiated in this species, as shown by the 

 figures given by Schlumberger in 1883, and by Silvestri in 1902. 



With regard to its general distribution in the living condition, 

 Brady in his ' Challenger ' Beport gives thirteen localities, at 

 depths varying from the shore to 1125 fathoms ; Egger quotes three 

 ' Gazelle ' Stations, at depths from 75 fathoms to 225 fathoms m r 

 whilst Fornasini and Silvestri record it from the Adriatic and 

 Mare Jonio.
