(Plate IX., figs. 104, 105.) 
Dentalium majorinum Mabille and de Rochefort, Miss. Scient. Cap Horn, vi., Moll., 
1889, p. 100, pl. iv., fig. 10; Jd., Pilsbry and Sharp, Man. Conch., xvii., 1898, 
p- 27, pl. xii., figs. 98, 99; Id., Plate, Deutsch. Siidpol. Exped., x., 1908, p. 5; 
Id., Smith, “ Terra Nova” Exped., Zool., 1915, Moll., p. 74. 
A Dentalium of frequent occurrence in the area examined is thus determined, and 
for more exactitude a figure is supplied of a specimen 36mm. long and 3-5mm. broad, 
from near the Shackleton Ice-shelf. Most are severely eroded; on better preserved 
material from 15 to 24 ribs appear; these increase by intercalation. An injured 
specimen is 47mm. long. 
There were dredged, December 28th, 1913, nine from 288 fathoms, ooze, off the 
Mertz Glacier Tongue, in South Lat. 66° 55’ and East Long. 145° 30’. One, January 
2nd, 1914, from 230 fathoms, ooze, off the coast of Wilkes Land, in South Lat. 65° 48’ 
and East Long. 137° 32’. One, January 28th, 1914, from 240 fathoms, ooze, off the 
Shackleton Ice-shelf, in South Lat. 65° 20’ and Hast Long. 95° 27’. In the same neigh- 
bourhood, two, January 29th, 1914, from 325 fathoms; one January 31st, 1914, from 
110 fathoms ; and four, January 31st, 1914, from 358 fathoms.
