Sagrina australiensis, n.sp. (Plate vi. figs.3a, &, c). 



This species has a uvigerine commencement, after which it 

 consists of a uniserial row of oval chambers cylindrical in section. 

 The character of the shell is intermediate between S. dimorpha 

 and S. virgula. The shell is thick, and studded with large pits 

 as in S. dimorpha. There are also tubercles externally approxi- 

 mating to the spines of S. virgida. The neck is as in *b\ virgula. 



There is a distinct constriction at the junction of the chambers, 

 and some of the chambers are produced outwards into small 

 monticular prominences (see fig. 3a). The chambers increase 

 gradually in size. 



Under a high power the surface appears as in fig. 36. On 

 focussing down, canals are seen in the walls, extending from the 

 interior and opening to the exterior in the small tubercles. 



Size: length 0-7 mm. 



This species is fairly common in the Palm Island dredgings.
