Polygyra sayii (Binn.). 



Paint Eock, south side, and Wilson's Cove, a few specimens with 

 no special characteristics. 



Polygyra chilhoweensis (Lewis). 



Paint Rock creek, on the north side of the river. Two speci- 

 mens only. This extends the range of this species considerably 

 farther north than has hitherto been recorded." 



Along the Cumberland plateau it has, however, a range consid- 

 erably farther north, having been found in Campbell county by 

 Wetherby." Similar specimens are now in the collections of G. 

 H. Clapp and Bryant Walker. It seems probable that the French 

 Broad valley is about the northern limit of the range of this 

 species along the Aj^palachians. 



Polygyra albolabris (Say). 



This species occurred only at Paint Rock, on the north side of the 

 river, where it is apparently quite abundant. AJl the specimens 

 are more or less deeply tinged with rose and one is obscurely 

 banded below the suture. They are very similar to the Cade's Cove 

 examples mentioned in the report on the " Pentadelphian " ex- 

 pedition. 

 Polygyra exoleta (Binn.). 



Paint Rock, south side, two specimens. Cat-tail branch, one 

 example. 

 Polygyra palliata (Say). 



Paint Rock, south side, four specimens, 22 to 24 mm. in diam- 

 eter; quite typical. 



Polygyra appressa perigrapta Pilsbry. 



Paint Rock, on both sides of the river. Bluff mountain and 

 Wilson's Cove. Koticeably smaller and more compressed than 

 those from the Smoky mountains. Of fifteen specimens from 

 these localities, the smallest was 15 J mm. in diameter, the largest 

 17^, average 16^ mm., while those from the Smoky region range 



" In the J, H. Thompson collection, now in the possession of one of 

 us, are two specimens labeled " Roan Mt. ex auctore." As the species 

 is not cited bj' "Wetherljy from Roan and there are no specimens from 

 that locality in the Lewis collection, now owned by jNIr. G. H. Clapp, it 

 seems probable that there is some mistake in regard to the Thompson 

 sliclls
