TUK NAUTILUS. 15 



determined the collections from this region, I am able to make the 

 following additions to the list published in the March number of the 

 NAUTILUS for the current year. It should be noted that some of 

 species listed then and now were not found on the mountain 

 proper, but, living on the foothills or in the adjacent valleys, are 

 entitled to enumeration in the fauna of the region. .

 land shells, collected near the base of the mountain.

 mountain.
