Hab.—Holdfast Bay (Angas), Largs Bay (Adcock), 
Yorke Peninsula (Matthews). 
I have specimens (whole or valves) from St. Francis 
Island (dredging and shore), Port MacDonnell, Carrowa 
(West Coast), Hardwicke Bay, Spencer Gulf (dredging), 
Kangaroo Island, Troubridge Reef, Glenelg, Brighton, Largs 
Bay, and Fowler Bay. Valves are frequently found in shell 
sand. Mr. A. R. Riddle informs me that he has found 
them on Pinna inermis, old boots and bottles, and especially 
near the roots of Zostera at an extremely low tide, by dredging 
or with a grappling-iron. They are rarely found in shallow 
water.

Type specimens found on seaweed, Troubridge Shoal, St. 
Vincent Gulf. 
I have specimens from Tapley Shoal living in Zostera 
(seaweed), dredged specimens from Spencer Gulf and off St. 
Francis Island, live specimens and numerous valves in from 
6 to 20 fathoms of water. Two large specimens were found 
by Mr. F. L. Saunders on seaweed at Aldinga; they mea- 
sured 95x3 mm. A number of yery fine variegated speci- 
mens of this chiton have been found near the roots of Zostera 
at Wool Bay and other places by Mr. A. R. Riddle. The 
largest specimen measures 17 x5 mm.

5) } 
Dredged in St. Vincent Gulf by Dr. Verco. I found 
one specimen in shell sand at Aldinga, and Mr. Zietz col- 
lected a pretty buff specimen from Largs Bay. ‘This species 
differs from 1. pilsbryanus in the rapid tapering of the tail 
valves. As I have not had access to the type specimens of 
either pilsbryanus or pallens, it may be that my specimens 
may have to be reconsidered.
