XIV. The Califoenian Region. 



This region I regard as stretching from the peninsula of Alaska to the Isthmus of 

 Panama ; probably it will eventually be necessary to subdivide it, but so few forms have 

 been described from that coast, that this course hardly seems advisable at present. From 

 the coast between Alaska and Kamtschatka no Cephalopods are known to me ; probably 

 they will be found like the other MoUusca from that region to be of Arctic types.
