Beachport, Aldinga, Ardrossan, Stansbury, Point Soutar, 
Minlacowie, Streaky Bay, and all along the West Coast to 
St. Francis Island, Albany (Western Australia), and San 
Remo (Victoria). Dr. Verco has dredged it in Gulf St. 
Vincent. 
Tom Iredale, in Proc. Mal. Soc., London. vol. ix., part 3, 
September, 1900, p. 155, quotes Dr. Thiele (“Revision des 
Systems der Chitonen,” i., p. 48), “that lweuri, Blainville, 
must replace the familiar asbestoides, Smith.”

After going through a great number of specimens of 
this species and A. granostriatus, I am unable to separate 
them. A series shows the striations in the dorsal area to vary 
from almost smooth to deep microscopic sulci. I have only 
one specimen of A. coai from New South Wales. If it had 
been found in South Australia, I should certainly put it in 
with A. bednalli. 
It occurs all around the coast of South Australia. Speci- 
niens in my collection are from the South-East (Port MacDon- 
nell, Middleton), Gulf St. Vincent (Second Valley, Norman- 
ville, Aldinga, Marino, Sultana Bay (Troubridge), Spencer 
Gulf (Corney Point, Minlacowie), West Coast as far as St. 
Francis Island. A number of very large specimens, mea- 
suring 30x 14 mm., were found at Kangaroo Island. I have 
similar ones from Port MacDonnell, Troubridge, and the 
West Coast.
