with lateral teeth less developed. This very rare and probably boreal shell has 



just been identified from Adm. SirE. Belcher's coll.]. 

 Cardium Calif orniense, Desh. [is not C. California-Hum ( = Nuttallii), Conr. ; but=C. 



pseudofossite, Rve., 1844. The name of Desh. is unfortunate, as his shell is the 



Kamtschatkan form with strong ribs. The Californian form is smaller, with 



fainter ribs,= Cl blandum, Gld.].
