C. torrianus, Hedley and Hull, Mal. Soc. Journ., March, 
1911, vol. ix., part 4. : 
Specimens of this very beautiful chiton were misnamed 
C. covt for some years till the comparison of C. jugosus, C. 
torrianus, and C. coat, by Hedley and Hull, /oc. cit. The 
concentric lines on all valves differentiate it from (. coi, and 
the sulcations of the pleural areas make it impossible to put 
it with C. jugosus. It is rarely found in the gulfs. I have 
collected it from Cape Jervis, Kangaroo Island, and Corney 
Point. Large numbers were found at the latter place by Mr. 
Walter Klem. Mr. Bednall reports it from Sultana Bay. 
I have South Australian specimens measuring 42 x25 mm. 
and Western Australian 52x29 mm. TI have collected it all 
around the coast of Western Australia from Esperance to 
iSoutatl MR prt.”

The pointed girdle scales differentiate this rare South 
Australian chiton from all others of the family in South 
Australian waters. I have only one specimen from Dr. 
Verco, labelled Hardwicke Bay, Spencer Gulf. Its colour 
is a pale-ochreous yellow with light- and dark-brown on the 
first, second, fourth, fifth, and anterior valve. The markings 
and girdle scales correspond with specimens of (. muricatus 
from New South Wales. 
Avrre 3\-Chiton exoptandus, Bednall, 1896. 
Chiton exoptandus, Bednall, Proc. Mal. Soc., London, vol. ii., 
part 4, April, 1897, p. 152. 
This “much desired’’ chiton is easily distinguished from 
others by the uniformity of its pinkish colour-marking so well 
described by Mr. Bednall, doc. cit. It runs through all the 
gradations of a pinkish-yellow to a burnt sienna. One speci- 
men in my possession has a uniform rich reddish brown strip 
the full length of the dorsal areas of each valve. I have 
specimens from Second Valley and valves from Normanyille. 
It is frequently found at Marino, Troubridge, and Edith- 
burgh, and is very plentiful at low tides in Wool Bay. I 
collected one small specimen in the crevice of a rock at Min-
