584 ORTMANN— NAYADES OF 



beyond the upper limit of L. ovata in the headwaters, where it is 

 found in its best development and as a pure race. In the Powell, it 

 goes to Olinger, Lee Co., A^a. ; in the Clinch, to Cedar Bluff, Taze- 

 well Co., Va. ; in North Fork Holston, to Saltville, Smyth Co., Va. 

 (also in Big Mocassin Creek) ; and in the South Fork, to Emmett, 

 Sullivan Co., Tenn. It is in Nolichucky River, at Chunn's Shoals, 

 Hamblen Co., Tenn. (inclining here toward ovata) ; in Little Pigeon 

 River, Sevierville, Sevier Co., Tenn. ; in Little River, Melrose, Blount 

 Co., Tenn. ; and in Emory River, Harriman, Roane Co., Tenn. I 

 have seen it also in Chickamauga Creek, Ringgold, Catoosa Co., Ga. 

 Type locality: Wisconsin River, and Mississippi River, Prairie du 

 Chien, Wis. 



73. Lampsilis fasciola Rafinesque (1820). 



Lampsilis fasciola Rafinesque, '20. — Unio miiltiradiatits and perra- 

 diaiiis Lewis, '71. — Unio mitltiradiatus Pilsbry & Rhoads, '96. — ' 

 Lampsilis multiradiata Ortmann, 'i2&^ p. 352 (anatomy). — Lamp- 

 silis mnltiradiata Ortmann, '13^^ p. 311. — Lampsilis multiradiata 

 Goodrich, '13, p. 95. — Lampsilis midtiradiata Simpson, '14, p. 55. 



Also in this case, I do not follow Vanatta's ('15, p. 551) de- 

 termination of the "type" of fasciola, but rely on Rafinesque's de- 

 scription, which indicates a shell of the cardium-ovata type, with 

 unequal, fiexuous rays, which fits multiradiata Lea, but not luteola 

 Lamarck. Moreover, Conrad, in 1836, held the same opinion, also 

 pointing out the undulated rays as the main character of this species. 



Practically everywhere in the larger rivers as well as in smaller 

 streams, but apparently more abundant, toward the headwaters. In 

 the Tennessee, South Chickamauga, Hiwassee, Little Tennessee, 

 Little River. In the French Broad drainage, going up here to Ashe- 

 ville, N. Car., and, in Big Pigeon River, to Canton, N. Car. In the 

 Holston, up to the South Fork at Barron, \\"ashington Co., Middle 

 Fork at Chilhowie, Smyth Co., and North Fork at Saltville, Smyth 

 Co., Va. Also in Big Mocassin Creek, and Watauga River. In the 

 Clinch, it goes up to Cedar Blufif, Tazewell Co., Va. ; in the Powell, 

 to the North Fork at Big Stone Gap, Wise Co., A'a. Also in the 

 Emory at Harriman, Roane Co., Tenn. 



Type locality: Kentucky River.
