132 AMERICAN SPECIES OP VERTIGO. 



Specimens from Bill Williams Mt., in northern Arizona are 

 particularly sharply striate. They were recorded as V. con- 

 cinula in Proc. A. N. S. Phila. 1911, 197, but on account of 

 their size, 2.4 to 2.5 mm. long, 1.4 wide, they appear more 

 properly placed here. The locality is far north of others 

 known, yet the whole intervening region is still unexplored 

 for shells. 



The specimens from the Chiricahua range, which were form- 

 erly recorded as V. modesta parietalis and V. concinnula ap- 

 pear to be better placed here. They measure 2.4 to 2.5 

 TTITTI. long. 



At several places in the Santa Catalinas Mr. Ferriss found 

 beautiful albino specimens. They have the translucent wax- 

 like texture of Gastrocopta pentodon or corticaria. In every 

 case they occurred in colonies of cinnamon-brown shells.
