figs. 7a-c. 
Observations. —X. polita has a limited distribution, hitherto being confined to 
two localities off South America (Falkland Islands and Straits of Magellan), The 
present specimens, from the west of Tasmania, are fairly typical.

pl, XXXI, figs, 2a-d, figs. 3a-c. Chapman, 1902, Journ. Linn. Soc. Lond. Zool., vol. 
XXVIII, p. 428, 
Observations.—Localities for this species have been hitherto confined to the 
colder parts of the Southern Ocean (Kerguelen, Heard and Prince Edward’s Islands), 
excepting in the case of dredgings at Funafuti, which yielded this species at 12-60 
fathoms, and also from the lagoon and beach sands at the same locality, 
Occurrence.—No. 59 (12th December, 1912), 1,320 fathoms.

Observations.—As another widely distributed form, this species has occurred off 
Cape Verde, off Tongatabu, at Funafuti; from New Caledonia, in the Fiji and Samoan 
Islands, and off South Australia. The present. occurrence is west of Tasmania, 
As a fossil its history dates back to the Miocene (Victoria), where these ancient 
specimens differ in no way from the living examples. 
Occurrence.—No. 59 (12th December, 1912), 1,320 fathoms.
