 Figs. 4, 5. B. bradii, Schl., var. denticulata, Brady, Chapman, 1909, Sub-Antarctic 

 Islands of New Zealand, vol. i, art. xv, p. 315, PI. XIII, Fig. 2. 



Two tests of this variety, closely resembling the recently figured example from 

 north of Auckland Island, New Zealand, at 85 fathoms, occurs in the floatings of the 

 Mount Erebus material.

Biloculina irregularis, d'Orbigny (Plate V, Fig. 2)

The present examples are of small size. In the latter feature they agree with the 

 sub-Antarctic specimens dredged twenty miles north of Auckland Island at 85 fathoms. 



Loc. No. 1, very rare ; No. 2, frequent.

This species is not common in the living condition, as regards the Southern Ocean. 

 It was a characteristic form in the dredgings amongst the sub- Antarctic islands of New 

 Zealand. It ranges into moderate depths, keeping generally near the 100-fathom 

 line. 



Two small, sub-rotund varieties, having the typical broad aperture, were found.

 Antarctic Islands of New Zealand, vol. i, art. xv, p. 324, PL XIV, Fig. 2. 



The gradual extension of the area affected by this striking species is further 

 augmented by its occurrence here in the Antarctic regions. At first known only from 

 the Arctic seas and the North Atlantic, it has since been found off Australia, between 

 there and New Amsterdam Island, and lately in the sub-Antarctic islands of New 

 Zealand. In the northern hemisphere it is a fairly deep water species. Numerous 

 specimens occurred in the washed material from the slopes of Mount Erebus, 160 feet 

 above sea- level.
