, This very hairy chiton, with a girdle, when alive, four 
or five times wider than the tegmentum, is rare. I have 
specimens from Aldinga, Marino, Stansbury, and St. Francis 
Island. Dr. Verco dredged some very large specimens in Gulf 
St. Vincent. I have one specimen from Stansbury with 
three very distinct horny riblets on the anterior valve. This 
may be a monstrosity or a new variety of speciosus. I found 
one specimen at Albany, Western Australia, in which the 
riblets in the interior valve are distinct but nodulose. Mr. 
Maughan EE Se oe washed ashore at Aldinga.

This is the most beautiful ‘and auneeie sculptured 
of all South Australian Acanthochitide. It somewhat re- 
sembles A. glyptus, Sykes, Proc. Mal. Soc., London, vol. ii., 
part 2, July, 1896, p. 92. I have specimens from Robe, 
Cape Jaffa, Normanville, Marino, and valves(?) from St. 
Francis Island. I have seen them collected by Rev. 
8. J. Martin at Wool Bay. Mr. F. L. Saunders has 
taken it at Port Victor. A number of specimens were 
taken from the stomach of a whiting caught near 
Edithburgh. Robe specimens in spirits measure 30x15 
mm. The girdle is very fleshy and wider than the valves 
themselves. They are of a very delicate milky colour, crossed 
with splashes of green. Pilsbry evidently had only a dried 
specimen. The specimens from Cape Jaffa and Normanville 
are of a ruddy tint-—stained, I think, by their proximity to 
some ferruginous matter on lighthouse or jetty. One remark- 
able feature in nearly every specimen collected has been the 
presence of a light-green marking at the beak of the dorsal 
area on the fifth valve. This helps to distinguish this shell 
in nearly every instance.
