I find no other localities for this mollusk recorded in the inter-mou- 

 tanic region, except that Mr. Lord mentions finding a " Zonites like 

 electrina^ Fort Colville, Columbia River ;" and Mr. Binney accredits it 

 to the Central Province. 



Remarks. — All of these localities were at the foot of mountains, and iu 

 each case the animals were found in the wet shaded ground beside run- 

 ning water. In the valleys of the Animas and La Plata, they were very 

 abundant under logs. 



Zonites iiidentatus^Ssij. — Accredited by Mr. Binney (Bull. Mus. ComfD. 

 ZooL, III, ix, 202) to the Central Province, as having been derived from 

 the north.

 comb).

Camp 26 : Cunningham Gulch, altitude 11,000 feet 1 specimen. 



Remarks. — No mention has been made of this species that I am aware

 VIII, 163), who quotes San Francisco, California, as its habitat.

Remarks. — My specimens vary in size and proportion, many being 

 young. The highest localities, it'^will be noticed, yielded the greatest 

 number of specimens, as Camp 24 (8,300 feet), Camp 26, and Camp P 

 (9,300 feet).
