SiGMOILINA siGMOiDEA, Brady, ftp. 



The occurrence of this species in the Southern Ocean is 

 of decided interest, since it had only been previously recorded 

 in the living condition in the Southern Hemisphere from 

 South America. It is found fossil, however, in the Tertiary 

 beds (Oligocene) of Port Phillip and Muddy Creek, in 

 Victoria, which area may have been the original point of 

 dispersion for this species. Dr. Egger recorded its occur- 

 rence off the West Australian coast at 82 metres. 



Station 36, east of Tasmania, 777 fathoms. One typical 

 specimen. 



Sub-Family HAUERININ^. 



Genus Ophthalmidium, Kiibler. 



Ophthalmidium inconstans, Brady. 



A fairly deep-water form, ranging " mostly between 350 

 and 1000 fathoms " — Brady. The writer has previously 

 recorded the species from Funafuti at 1050 fathoms. Dr. 

 Egger obtained his " Gazelle " specimens from a sounding 

 off the coast of Western Australia at 1187 metres. 



Station 36, east of Tasmania, 777 fathoms. Abundant ; 

 examples in good condition and well developed. 



Genus Planispirina, Segiienza. 

 Planispirina exigua. Brady. 



The occurrence of this species at 777 fathoms constitutes 

 a record for deep water, 620 fathoms being apparently the 

 deepest habitat hitherto known. Egger obtained specimens 

 from off the coast of Western Australia at 359 metres.
