 MIL figs. la-d. 

 This species has been identified by Frierson (42, p. 7) and Ortmann 

 (82, p. 39) as Unio (Leinio.v) riiiiosiis Raf. and the latter (1. c.) has raised 

 Leiniox to generic rank. The identification seems too doubtful (Walker, 

 162, p. 4) to be relied upon, the species should therefore retain Conrad's 

 name and a new generic name proposed.

This is the form that was collected by Ferriss in 1900 and distributed 

 "by him as T. deviata (Anth.). It has also been found in Bear Creek, Frank- 

 lin Co., Ala., a tributary of the Tennessee. It does not seem to be more 

 than a light colored form of that species.

 Type locality : Black River, Williamsville, Mo. 



Truncilla foliata (Hild.). 



This species has been identified as Rafinesque's Obliquaria flexuosa by 

 Conrad and the specimen in the Poulson collection under that name is stated 

 by Vanatta (140, p. 550) to be this species. If identifiable from the orig- 

 inal description, Rafinesque's name would have priority. It has also been 

 identified by Frierson (42, p. 7) as Rafinesque's Epioblasma biloha.
