Hab. — Coast generally. 



Obs. — We have a large series of specimens before us of 

 different sizes and varying stages of growth, on some of which 

 the dark brown markings are absent. Tryon considers that A. 

 monilifera, Reeve, A. lineata, Kiener, A. oblonga, Sowerby, and 

 A. obesa, Sowerby, are all young shells of A. niarginata. With 

 this we cannot agi'ee. We have carefully examined and compared 

 specimens of all of these species excepting A. obesa, and consider 

 them to be valid species.
