ObservatioJis. — The specimen from the bore, at a Kalimnani 



horizon, is in every way typical. 



As a recent species this form occurs in the Southern Ocean at 

 Kerguelen Island; at Port Jackson in New South Wales, at Booby 

 Island, Torx-es Strait, and in the Pacific Ocean at Honolulu, Fiji, 

 and New Caledonia.

 ixi., abth ii., p. 456, pi. iii. figs. 27-30. 

 Observations. — This species occui-s in the Mallee bores at the 

 top of the Janjukian series, thus showing the specimens to have 

 lived in Miocene times. 



In the living condition, X. margaritea. is known from the- 

 Mediterranean and off Booby Island. Torres Strait. 

 Occurrence. — Bore 11, 267-270 feet (Janjukian).

 Observations. — In the living condition this species has occurred 

 at Cape Verde, Tongatabu, Fiji, Samoa, Funafuti and New Cale- 

 donia, in depths varying from shallow water to 1150 fathoms. I' 

 have lately found this species in a sounding by F.I.S. " Endea-
