56 THE NAUTILUS. 



Thunderhead only. Dn not remember of ever finding the typical 

 hirsuta in these mountains. 



141c. Poly, monodon cineta (Lewis). Tuskeegee Creek, Yellow 



Creek, Mt. Hayo, Clen Cove, Talassee Ford. 



180a. Strobilops labyrivthica sirebeli (Pfr.). Cade's Cove, Yel- 

 low Creek Mountains. 



187. Bifidaria contractu (Say). Cade's Cove. 



194. Bifidaria corticaria (Say). Cade's Cove. 



225. Vertigo govldii (Bid.). Cade's Cove. 



226. Vertigo bollesiana. (Morse). Cade's Cove. These four species 

 very rare. 



235. Cochlicopa lubrica (Mull). Sugar Cove in Cade's. One 

 specimen by Sargent. 



239. Circinaria concava (Say). General. Largest 23^ diam. 



246a. Omphalina fidiginosa polita (Pils.). Cade's Cove, Coon- 

 town, Chambers' Creek, Talassee Ford. At the two last named 

 places on the Little Tennessee the shells were as light colored as the 

 typical fidiginosa, but polished. There were no black forms at these 

 points. 



248. Omphalina Icevigata (Pfr.). Cade's Cove, Cheowah river. 

 Only a few found at the latter place and these were dark colored 

 and as well polished nearly as Omp. Andrewsce. Largest 20 mm. 

 diam., 12 altitude. 



248a. Omp. Icevigata perlcevis (Pils.). n. var. Talassee Ford. 



248b. Omphalina Icevigata latior (Pils.). n. var. This variety 

 has given me trouble since I saw it on my first trip to Tennessee. 

 It is much larger than type, much depressed and a light " Melantho" 

 blue in color. As 1 read shell music by ear, it has very little re- 

 semblance to the typical form. The largest from Talassee Ford 

 measured 28 diam., 10 altitude. Also found at Chambers' Creek. 



250. Omphalina subplana (Binn). All along the route in damp 

 rnoss. On the Unakes the shells were very fragile, sometimes the 

 shell was a mere membrane but large and healthy otherwise. It is 

 as much of a cannibal as concava. Largest (Mt. Hayo) 24 diam.. 

 10 altitude. 



252. Omphalina andrewsce (Pils.). All along the route. In 

 Cade's Cove there is a light colored form, faintly banded with darker 

 color. Largest 18 mm. in diam. 16 is large. 



252a. Omp. Andrewsce montivaga (Pils.). Cade's Cove, Mi rev
