62 AUSTRALASIAN ANTARCTIC EXPEDITION. 
and has the apex within the margin. 
New Zealand, Mr. T. Iredale has proposed the name Kerguelenia innominata.* . I have 
not the means to institute a comparison between that and the Macquarie Island shell. 
Specimens of Kerguelenia brought from Macquarie Island by Mr, A. Hamilton in 1894, 
differ from the present series by being larger, with the apex further inwards from the 
margin, more radially furrowed, and of a paler colour. Perhaps they represent 
K. lateralis Gould.

Though it is so minute this snail is important because it is the most southern of the 
world. 
Mr. A. Hamilton, the discoverer of this small species, found it to be plentiful in 
decaying vegetation at Lusitania Bay. His son, Mr. H. Hamilton, found 30 specimens, 
December 15th, 1911, on stems of the “ Maori Cabbage,” + near Charlotte Cove, and in 
August, 1912, he collected 17 specimens in rock crevices, under tussocks, and in Stilbocarpa 
polaris, at Garden Bay, north-east end of Macquarie Island. 
AGRIOLIMAX AGRESTIS Linne. 
Agriolimax agrestis Taylor, Monog. Brit. Land and f. w. Mollusca, 1903, p. 104. 
This small European slug has been introduced, occurring about the roots of 
Stilbocarpa polaris and under wood and stones, near the huts at Lusitania Bay, Macquarie 
Island. 
TURBONILLA LAMYI sp. nov. 
(Plate IX., fig. 100.) 
Shell small, rather solid, subcylindrical. Colour buff. Remaining whorls six, 
rather flattened medially and constricted at the suture. Base rounded, unsculptured. 
On the last whorl there are 17 strong, perpendicular ribs, ceasing abruptly at the 
periphery and failing to undulate the suture. These are parted by deeply excavate 
intercostal spaces of the same breadth. There is no spiral sculpture. Aperture 
rhomboidal, columella perpendicular, thickened, with a slight median twist. Length 
3:6; breadth, 1-Imm.
