326 PROCEEDINGS OF SECTION D. 
Notiodrilus, Diporocheta, and Microscolex, and these I must 
trace further. 
Notiodrilus is a comparatively large genus, containing 
altogether 30 species, some of which occur in Australia, 
others in South Africa, and others in South America. 
There are four species hitherto recorded from Australia : — 
NV. eremus (Spen.), found by Spencer in three locali- 
; ties, separated by desert, in Central Australia. 
during the Horn Expedition. 
N. macleayi (Fletcher), on the Napier Range, in 
N.W. of the continent. 
NV. australis (Michaelsen), at Cape York, in Queens- 
land. 
NV. schmarde (Beddard), in fresh water, in Queens 
land. 
These four species are all somewhat divergent from the 
New Zealand species, and, with the exception of the first, are 
imperfectly described. 
_Passing westwards, we meet with one species on Kerguelen 
Island, and the same species is found in Marion Island. 
At the Cape of Good Hope five species have been recorded. 
From South Georgia one species. 
From Falkland Islands two endemic species. 
From Fuegia, Patagonia, Chili, and Argentina, five other 
species, of which one also occurs in the Falklands. 
Quite recently, moreover, three species have been recorded 
from Guatemala, and one from Mexico, while the remaining 
two species come from Madagascar. 
This is certainly a very interesting distribution, and be- 
comes more so when we find, as Beddard was the first to 
point out, that the Macquarie Island species is more closely 
allied to the Patagonian and to those from the Antarctic 
islands than to the New Zealand species; while I find that 
the Auckland Island species bears still closer resamblance to 
the South American forms. Further, Beddard states :— 
“The Cape species are so like those of South America 
that I have more than once doubted whether I had not be- 
fore-me identical forms from these widely-distant localities.” 
Now, the genus Notzodrilus is allied to, and ancestral to. 
another genus. Chilota (Mchlsn.), distinguished from it by 
possessing one pair of testes, just as Weodrilus is distin- 
guished from Maoridrilus by having only one pair of certain 
organs instead of two pairs. , 
Chilota, containing 30 species, is abundant in South 
America, where 18 species are recognised. Falkland Island 
possesses one peculiar species (Ch. dalez), while the remaining
