This species appears to be more generally met with in soundings from the northern 

 hemisphere ; but it is also fairly well distributed in the Southern Ocean. It occurs 

 in the dredgings from Great Barrier Island, off New Zealand, but was not recorded 

 from the sub -Antarctic islands. 



Two typical examples were found in the elevated deposit from the slopes of 

 Mount Erebus.

It is interesting to note that this species is rare in these deposits, whereas in the 

 elevated material south-east of Mount Larsen it is common ; whilst in the case 

 of the next recorded form, T. lobatula, the reverse obtains. This points to the inter- 

 relation of the two forms, probably influenced by bottom conditions rather than 

 depth, as they both have an unrestricted range. In the one case, from near Mount 

 Larsen, the deposit being silty, the high conical form flourishes ; in the other, where 

 the deposit is cleaner, sandy, and fragmentary, the low, plano-convex shell is the 

 prevailing form.

Truncatulina lobatula, Walker and Jacob, sp. 

 (For references see previous Report) 



This species is the commonest form in these deposits. It shows some variability, 

 in that the usually flat base tends to become concave in one direction, as though it 

 were endeavouring to build on a cylindrical surface. No attached examples, however, 

 were found.

One example found. Typical specimens are not at all common in recent soundings. 

 This species has previously occurred at a few stations in the Southern Ocean. It has
