This elegant little species is apparently almost confined to 

 the Southern Hemisphere. It has already been found off 

 the shores of New Zealand, and is a well-known Australian 

 species. Our specimens have the keel strongly accentuated, 

 and the chambers showing a nodulous appearance on the 

 inferior surface as in Brady's figure 2. 



Not common in our sample.

T. reticulata has been previously found in the South 

 Pacific, but it does not seem to have been recorded from the 

 neighbourhood of the present locality. It is very rare in our 

 series. 



Truncatulina wuellerstorfi, Schwager sp.

The above species is represented in the present series by a 

 fair number of specimens. It does not appear to have been 

 recorded from the vicinity of Great Barrier Island. 



Brady regards this form as of essentially deep-water habit. 

 In the South Pacific its range in depth is from 210 to 1940 

 fathoms, so that it is rather surprising to meet with so many 

 typical specimens in our sounding at 110 fathoms.
