Supl. lot 124. Knoxville, Term. Looneys Island, about 9 miles below Knoxville. Col- 

 lected by Sam George and Henderson. September 26, 1901. These are the form angitremoides. 



Lot 100. Lyons Shoals, about 12 miles below Knoxville, Tenn. Collectors, Sam George 

 and C. C. Adams. October 7, 1900. A few individuals of loudonensis, but shells with spinose 

 apices turrita, are predominant in this large series. 



Supl. lot 101. Lyons Shoals, about 12 mUes below KnoxviUe, Tenn. October, 1900. 

 Collector, Sam George. This is a series of completely spinose shells. There is a chance that 

 I have transposed the data of lots 100 and 101, but the localities are in close proximity. 



Supl. lot 102. Williams Shoals, 14 miles below Knoxville, Tenn. October 11, 1900. Col- 

 lector, Sam George. This lot is composed almost exclusively of spinose turrita shells and a very 

 few of loudonensis. 



Group 23. Lot 105. Little River Shoals, at the mouth of Little River, 16^ mUes below 

 Knoxville, Tenn. A series loaned by the late Mrs. George Andrews, of Kjioxville, Tenn. A very 

 large series, of several hundred, composed of loudonensis and turrita. 



Supl. lot 103. Little River Shoals, 16^ miles below Knoxville, Tenn. Collectors, Sam George 

 and Henderson. October 11, 1900. Eighty-two shells not mature, a few of loudonensis, but 

 the great majority are turrita. 



Group 24. Lot 152. Loudon, Tenn. About Sams Island and downstream to HuflFs Ferry. 

 Collected in fall of 1901 by W. L. Julian. This is a very large series of several hundred speci- 

 mens, only a part of which has been used for statistical study. About 48 miles downstream 

 from lot 105; from the headwaters about 65 miles. Mainly of the form loudonensis, a very few 

 individuals of turrita. 



Supl. lot 126. Loudon, Tenn. September 30, 1901. Collectors, W. L. Julian and C. G. 

 Adams. Loudonensis and a very few of turrita. 



Supl. lot 134. Loudon, Tenn. Collected by W. L. Julian, fall of 1901. Loudonensis, with 

 a very few of turrita. 



Supl. lot 130. houdon, Tenn. Collected by W. L. Julian. Late in September, 1901. Four- 

 teen specimens, loudonensis and turrita. 



Supl. lot 189. Loudon, Tenn. Sams Island and Huffs Ferry. Collected by W. L. Julian 

 in the spring of 1904. 



This group is one of the finest series of lo shells secured from any locality, and much credit 

 falls to W. L. Julian for his faithful work in collecting them. 



The Little Tennessee River empties into the Tennessee River opposite Lenoir, Tenn. This 

 is about 15 miles upstream from Loudon. On October 1, 1901, 1 examined the Little Tennessee 

 at Coytee, where there is a shoal. Several small islands were also examined, but although the 

 condition of the water looked favorable no lo shells were found. A little later in the season 

 W. L. Julian repeated the examination at Coytee Shoals and also examined the stream at Car- 

 penters Island. Although the river was very low, he found no shells. This stream largely drains 

 a nonlimestone area. 



The Clinch River joins the Tennessee at Kingston, 104 miles above Chattanooga and about 

 84 mUes from the headwaters of the Tennessee. 



Group 25. Lot 155. Rockwood Landing, King Creek, Tenn. Dead shells from an Indian 

 shell heap near the ferry landing, on the east bank of the river. This locality is about 15 miles 

 below the mouth of the Clinch River at Kingston, Tenn., and 38 miles below Loudon; about 99 

 miles from the headwaters. Kingston sheet. A series of large individuals of turrita and lou- 

 donensis. Consult plate 53.
