64 THE NAUTILUS. 
The occurrence of Pupa syngenes Pils., previously known only 
from Arizona, and of Planorbis umbilicate//us Ckll., described and 
reported only from Manitoba, are especially interesting. Many of 
the forms were identified at the National Museum by Messrs. Dall 
and Simpson, while Dr. Sterki has kindly named the Pupide and 
Vallonias. Mingusville is two thousand six hundred and forty-five 
feet above sea level.
