THE NAUTILUS. 83 



Zonitoides arboreus (Say). 



Btfidaria pilsbryana Sterki. A form with the crest more devel- 

 oped than in the type, and the palatal folds standing upon a callous 

 ridge. 



In this connection I may mention that a specimen of Bijidaria 

 hulzingeri (Sterki) has been found among minutiie collected by Prof. 

 Cockerell at Mesilla, N. M., in drift of the Rio Grande. So far as 

 I know, this species has not been reported before from west or south- 

 west of Wichita, Kansas. 



Ashmunella chiricahuana (Ball) has been collected by Prof. E. O. 

 Wooton in a pine region on the west fork of Gila River, n-ar 

 Mogollon Peak, N. M.

This is a very distinct species, and at once recalls to mind a large 

 and more globose Helicigona pyrenaica with a closed umbilicus. It 

 is provisionally referred to Euhadra, but the generic position is diili- 

 ciilt to ascertain. A single dead example was obtained, and is in 

 my collection. With this I received a fine example of the very rare 

 Helicarion Bottgeri, Hilber, of which the Austrian expedition of
