56 THE NAUTILUS. 



Thunderhead only. Do not remember of ever finding the typical 

 hirsuta in these mountains. 



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

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



180a. Strobilops Idbyrinthica strebeli (Pfr.). Cade's Cove, Yel- 

 low Creek Mountains. 



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



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



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



22G. Yerti(/obollesiana( 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 fuliginosa 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 fuliginosa, but polished. There were no black forms at these 

 points. 



248. Omphalina Itevigata (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 inm. 

 diam., 12 altitude. 



248a. Omp. IcEvigata perlczris (Pils.). n. var. Talassee Ford. 



248b. Omphalina lavigata 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. Omplialina 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, Mirey
