REPORT ON FORAMINIFERA AND OSTRACODA 33 



This species is one of the most abundant of the smaller forms in the present series. 

 The tests are fairly typical, but the inflation of the last few chambers tends to obliterate 

 the usual feature of the trifacial compression of the test, at the oral extremity. 



In the living condition U. angulosa is found at various depths in the N. and S. 

 Atlantic, the Mediterranean, the Indian Ocean, the N. and S. Pacific, and the Southern 

 Ocean to the Antarctic ice barrier. It was an abundant species in the dredgings from 

 the sub-Antarctic islands of New Zealand. As a Pleistocene fossil it has been recorded 

 from Norway and the N.E. of Ireland.

One typical shell was found in the present deposit. As a living species it does 

 not appear to have been found farther south than the Victorian coast of 

 Australia. It inhabits water of moderate depths. It occurs as a Pleistocene fossil 

 in Norway.

A well-formed test of this species having the characteristic brownish-pink colora- 

 tion of the initial series of chambers was found in the raised beach material. It is a 

 widely distributed form, and mainly affects shallow water. The closely related 

 D. araucana was recently recorded from the sub-Antarctic islands of New Zealand.

A common shell in the present deposit. 



Among the many interesting forms of foraminifera which appear in the northern 

 and southern areas, but are absent from the tropics, this is a noteworthy example. 

 Its bathymetrical limits are wide. As a fossil it has been obtained from the Pliocene ; 

 and it occurs also in the Pleistocene deposits of Norway and the N.E. of Ireland.
