Swpl. lot 182. Deadericks Island (?); 3 miles below EmbreviUe, Tenn. Presented by 

 H. M. Deaderick. Two smooth shells. 



Swpl. lot 117. Limestone, Tenn. Dead shells (42) from an Indian camp, 2^ mUes below 

 Limestone, Tenn. About 13 miles below Conkling. These are unakensis. In one shell a high 

 keel replaced the normal spines.

 nolichuckyensis. 



Supl. lot 80. Near the Joseph Thompson farm, Springvale, Tenn. September 5, 1900. 

 About 60 miles from Conkliag. 



Supl. lot 220. From the Joseph Thompson farm, Springvale, Tenn. On the bottoms of the 

 Nolichucky. 



Lot 83. East of White Pine, Tenn. A shoal with large bowlders, September 7, 1900. About 

 10 miles below lot 80. 



Lot 104. White Piae, Tenn. Collected by J. J. Thompson, October, 1900. Morristown 

 sheet. Near the mouth of the Nolichucky. These are the form nolichuckyensis. 



b. French Bioad River. 



Above the mouth of the Nolichucky the French Broad was examined at AshevUle, Hot 

 Springs, and Paint Rock, N. C, and at Bridgeport, Tenn., where a fine shoal was found but 

 no trace of lo. Upstream from this point the area drained by the French Broad is out of the 

 limestone area so that these shells could hardly be expected, and search confirmed this. The 

 Big Pigeon River was examined at Newport, Tenn., where fine shoals were found, but there was 

 no evidence of the sheUs. It thus seems fair to conclude that lo does not extend its range far 

 above the mouth of the Nolichucky. The upper limit of lo in the French Broad is given by the 

 single shell found below the mouth of the Nolichucky Got 82) on Hills Shoals. 



Group 21. Supl. lot 82. Below the mouth of the Nolichucky, in the French Broad River, 

 on HiUs Shoals, Term., September 6, 1900. A single immatiure shell of noiicJiuclcyensis.

 A series of 72 shells. 



Lot 137. Hanging Rock Shoals, Boyd Creek, Tenn. Collector, Sam George, October, 1901. 

 About 46 miles below the mouth of the Nolichucky River. About 25 mUes above the mouth

Supl. lot 166. Seven Islands Shoals, northeast of Gap Creek, Tenn. Collector, Sam George, 

 November, 1901. About 57 miles from the mouth of the Nolichucky and 15 miles from the 

 mouth of the French Broad. Knoxville sheet. Almost exclusively loudonensis, one shell of 

 turrita (No. 55). A plate was once planned of these shells, but as they were so much like the 

 shells on plate 49, figures 1 to 16, the plate was not used. 



Supl. lot 195. Seven Islands, Gap Creek, Tenn. Dead shells (22) from an old Indian camp 

 on an island opposite the mill. All are turrita, some aire very large and heavy shells 



The Little Pigeon River was examined about Catlettsburg, Tenn., and also about its mouth, 

 but no lo were found.

 Rivers, about 4^ mUes above Knoxville, Tenn. Consult Robert, 1893, pp. 33-35, for table of
