This species (from the Califomian coast ?) bears a striking resem- 

 blance to the Atlantic Purpura lapillus, and is intermediate between 

 it and the Purpura decemcostata of Middendorff, from the Icy Sea at 

 Behring's Straits, the place of which it probably takes on the western 

 shores of North America. 



Purpura, nov. sp. ? A single specimen, to which I abstain giving 

 a, name, since i^^s char.acters are internxediflte between tho?^^. of. </e-
