Fupa columella, Benz. var. Gredleri, Clessin. Same aa last. 

 Pupa Kravaaeana, Reinh., p. 38. Alaska. 



Selenitea Voyana var. aimplidlabria, Ancey, Le Nat. IV, p. 110, 111. This and S. 

 Duranti form subgenus Haptotrema. 



Mesodon armigera Ancey. — The type kindly loaned me by Mr. Ancey 

 shows this to be the large form of Stenotrema germanum, forming a 

 connecting link to Mesodon Columbianus. It will be noticed that ger- 

 manum is sparsely hirsute 5 Columbianus more crowdedly so, but armi- 

 gera is still more covered with hairs. I have this form from San Fran- 

 cisco, Santa Cruz, Watsonville, and other California locajities. 



Pupa sublubrica Ancey. — White Pine, Nevada. Seven whorls; gen- 

 eral outline of badia; aperture very much like that of same as figured 

 in Terr. Moll., III.
