Anisoradsia mawlei, I. and M., subspecies saundersi, Ashby. 



(Trans. Roy. Soc. S. Austr., vol. xlii., 1918.) 



In my "Notes on South Australian Polyplacophora" I 

 gave a brief description of a. new chiton, giving it the name 

 of saundersi, and placing it, with some doubt, as a subspecies of 

 Anisoradsia mawlei, I and M. Since my return from America 

 my friend Mr. W. L. May has supplied me with some splendid 

 specimens of that species, and I can now authoritatively say 

 that I was wrong in placing it in that genus. I am sending 

 the type to Mr. Iredale for his comments, as in 1917 I sent 

 him a second specimen collected at the same time and place.
