1. Argobuccinum oregonensis. Red- 

 field. The Oregon Triton. Alaska to 

 Puget Sound. They are covered with a 

 hairy periostracum which, if removed 

 shows a handsome white shell, but to my 

 notion looks best in its attractive coating, 

 well illustrating cold water shell.

Carpenters Tower Shell. Monterey Bay

4. Ranella Californica. Hinds. Cali- 

 fornia Frog Shell. Monterey to southern

 brown shell but you get no idea of its 

 beauty as taken from the water, as it 

 being usually covered with incrustations 

 of all sorts. Lives on mud flats and is 

 one of the finest Ranellas in the world.

 tractive shell and not real common.
