C. torrianus, Hedley and Hull, Mai. Soc. Journ., March, 

 1911, vol. ix., part 4. 



Specimens of this very beautiful chiton were misnamed 

 G. coxi for some years till the comparison of C. jugosus, C. 

 torrianus, and C. coxi, by Hedley and Hull, loc. cit. The 

 concentric lines on all valves differentiate it from C. coxi, and 

 the sulcations of the pleural areas make it impossible to put 

 it with G. 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 x 25 mm. 

 and Western Australian 52 x 29 mm. I have collected it all 

 around the coast of Western Australia from Esperance to 

 Fremantle.

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 Math specimens of G. muricatus 

 from New South Wales.

Chiton exoptandus, Bednall, Proc. Mai. 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, loc. 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 Normanville. 

 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-
