Rahitat. — Britain; European Seas; Mediterranean; Madeira; Jef- 

 freys. Jamaica, West Indies (introduced), Barrett; east coast of tbe 

 United States, probably; not yet clearly determined as distinguished 

 from Leuconia hidentata. San Francisco Bay, California (introduced), 

 Cooper. 



The synonymy of this species might have been much enlarged, but 

 to no particular purpose. Both the animal and its shell of A. setifer 

 agree with British examples and not with the form described by Gould, 

 which is a Leuconia. It is i)robable that when search is made, with 

 the distinctions kept in view, this species will be found on the eastern 

 coast of the United States wherever Leuconia exists, both being doubt- 

 less introduced species. I have not heard of either south from New 

 York.
