 in the present series. It has already been recorded from the

This species is distinguished by its long, slender, recurved 

 test, with oval segments. It is not uncommon in the present 

 series. Some of the specimens have a bulbous commence- 

 ment, whilst others have the extremity attenuated and finely 

 pointed. The latter variation agrees with the form figured by 

 d'Orbigny under the name of Dentalina elega><s. 



N. (D.) filiformis has been recorded from the South Pacific, 

 but not from the neighbourhood of Great Barrier Island.
