Is very rare in the Malay Archipelago, and has been observed only 

 at Station 2 in Area 1.

Bulimina Williamsoniana Brady, 1881, Quart. Journ. Micr. Sci., 

 vol. xxi. n. s. p. 56 ; and 1884, Chall. Kept., p. 408, pi. Ii. figs. 16, 17. 



This interesting species, although of well-marked characters, has 

 been strangely overlooked by Rhizopodists, and all that is known 

 about it seems to be comprised in the ' Challenger Report.' Accord- 

 ing to Brady it appears to be limited in its distribution to the South 

 Pacific. 



It is by no means uncommon in Torres Strait and at various places 

 on the Australian coasts. 



In the Malay Archipelago it is abundant at Station 2, and occurs 

 also, but very sparingly, ' at Station 6. It has not been noted at 

 other Stations more remote from the Australian region.

This admittedly abnormal form, although classed with the Textu- 

 laridse, does not possess the true Textularian plan of growth, inasmuch 

 as the chambers do not alternate in the sense that each successive 

 addition shifts the aperture from one side of the test to the other. 

 The plan of growth is rather Rotaliform ; a primary row of chambers 

 having applied to it a secondary row analogous to the " asterigerine " 

 flaps found in the genus Discorbina. 



The aperture, which is not always apparent, consists sometimes of 

 a horizontal slit, at other times of a small funnel-shaped depression, 

 and is situated on the septal face of the primary chamber, at the
