NO. 2.] SNAILS OF THE GENUS 10— ADAMS. 25 



Lot 184- Moon Bar, above Bells Landing, above the mouth of Hiwassee Kiver, east of 

 Dayton, Tenn. October 8, 1901. Four shells of loudonensis. 



Lot 151. Head of Hiwassee Island, at the mouth of the Hiwassee River. East of Dayton, 

 Tenn. October 13, 1901. Shells in deep water, knee to waist deep. About 150 miles from the 

 headwaters. A series of 30 specimens, mostly large individuals of loudonensis. 



Supl. lot 203. Chattanooga, Tenn. Taken from the Tennessee River just above the 

 Cincinnati Southern Railway bridge. October 5, 1904. Collector, J. Jones. 



Lot 201. Chattanooga, Tenn. Just above the Cincinnati Southern Railway bridge in the 

 Tennessee River at the Balon Bar. Collected in 1903 by Charles Pollard. Three shells of 

 loudonensis. 



Lot 202. Chattanooga, Tenn. Just above the Cincinnati Southern Railway bridge in the 

 Tennessee River. October 5, 1904. Collected by J. Jones. About 181 miles from the head- 

 waters. Fourteen specimens of loudonensis. 



Supl. lot 199. Chattanooga, Tenn. Taken above the Cincinnati Southern Railway bridge, 

 above the city at Walkers Island. Collector, Charles PoUard. A fresh specimen of loudonensis 

 and a dead one of turrita. 



Supl. lot 200. Chattanooga, Tenn. Large dead shells taken from an Indian mound on the 

 Hunter farm 15 miles northeast of city, by G. D. Barnes, of Chattanooga. Two large specimens 

 of turrita. 



This group of shells covers a long stretch of the river, about 90 mUes, but this has been 

 necessary on account of the very rapid reduction in the number of specimens below Loudon, 

 Tenn. Chattanooga is 188 miles from the headwaters of the Tennessee River and 104 miles from 

 the mouth of Clinch River. 



The Hiwassee River was examined October 9, 1901, but the conditions were not favorable 

 on account of high water. An island about a mUe above the new Kincannon Ferry was exam- 

 ined but no shells were found. This stream is too well graded for lo. It is depositing, as is 

 clearly evidenced by the extensive mud banks which line the stream, and there were no shoals. 

 These are conditions unfavorable for lo. The stream was again examined on October 16, at 

 Charleston, Tenn. (Cleveland sheet), but here again the river was up. A local river man 

 did not know the shell, nor were any found in the old Indian camps, although other molluscan 

 shells were found in such places. The mud banks here were much like those at the mouth of the 

 river. 



South Chickamauga Creek was examined on October 21, 1901, at Ringgold, Ga. I had been 

 told that the shells were here, but no evidence of them was found. Some places looked favora- 

 ble, except that the stream appeared to be much too small. 



Below Chattanooga the Tennessee River enters the ' 'mountain section " where it traverses 

 the mountain for about 40 miles and is then joined by the Sequatchie River. This smaU river 

 was examined October 29, 1901, at Dunlap, Tenn., about 32 miles above the mouth. Where 

 the stream was not dammed, it was about 75 or 100 feet wide. At the time the examination 

 was made the water was quite clear and several miles of stream were thus carefully examined 

 but no specimens of lo were found. A local fisherman who had fished much of the stream had 

 not noticed this kind of shell. 



A few miles below the mouth of the Sequatchie, at Bridgeport, Ala., several bars and other 

 favorable looking habitats were examined without finding even dead shells. So that below Chat- 

 tanooga I found only one Uve lo, all the others were deal shells, and aU of these were found at 

 the sites of old Indian camps on the banks of the river. 



Group 27. Supl. lot 186. Bridgeport, Ala. On the Widows Bar, 4 or 5 miles above the 

 town. I was told that the Government officials had blasted out this bar about three years pre- 

 viously. A single five specimen and the last live shell that I found was taken October 26, 1901. 

 It gives the downstream Umit of five lo in my collecting. About 50 miles below Chattanooga, 

 and 237 miles from the headwaters, the junction of the Holston and French Broad, above Knox- 

 ville. This is an immature specimen of loudonensis.
