SUTER: NEW ZEALAND ATHORACOPHORID®, yay | 
specimen in my collection is 90 mm. long, foot 10 mm. broad, and was 
found on a birch-tree near Collingwood. It is thus evident that this 
species, in a genial, moist climate, attains to the largest size of all our 
native slugs. 
Hab.—Auckland Islands (Krone); Collingwood, South Island. + 
Conctuston.—The geographical distribution of the species is not 
without interest. The North Island has only small, not much differen- 
tiated forms—A. bitentaculatus, A. antipodarum, and small forms of 
A. papillatus; whilst in the South Island, large, more differentiated, 
and generally darker-coloured species occur. Of the eight species all 
are found on the South Island, but the larger forms prevail, especially 
A. papillatus. Two species occur as far south as the Auckland Islands. 
We know nothing of any native slugs and very little about the other 
land mollusca from Stewart Island. There is no reason why Athoraco- 
phorus should not exist on this latter island, and it is even probable 
that new species may be found on it some day. 
Like the unfortunately extinct Moa, <Athoracophorus attains its 
greatest development and differentiation on the South Island. The 
comparison may seem somewhat peculiar, but it is quite in accordance 
with the facts. 
The genus Athoracophorus is restricted to New Zealand, including 
the Chatham and Auckland Islands. The two other genera of the 
family are found: Aneitea, Gray, in East to North Australia, New 
Caledonia, and New Hebrides; ? Anectella, Cockerell, on Wild Island, 
Admiralty Archipelago. The occurrence of members of the family in 
New Guinea is to my knowledge not quite certain yet, but they seem 
to be absent from the Kermadec, Norfolk, and Lord Howe Islands. 
Mr. C. Hedley included Hyalimax, H. & A. Ad., in the family,! but 
according to Dr. Simroth this genus is much nearer the Succineide and 
has nothing whatever to do with the Athoracophoride.
