OuADRUEA pustulosa pernodosa (Lea). 



According to Vanatta (140, p. 557) the Obliquaria bullata Raf. of the 

 Ponlson collection is this form, but the name is preoccupied by Obliquaria 

 flexuosa bullata Raf. and Lea's name will stand. 



OUADRVEA PYRAMIDATA (Lea). 



Unio plenus interduos De Gregorio, Moll, di aq. dul. di Amer., 1914, p. 18. 

 According to Ortmann this is probably only a form of obliqua (Lam.). 

 Vanatta states (140, p. 557) that the Obliquaria rubra Raf. of the Poulson 

 collection is this species. If identifiable from the original description, rubra 

 would have priority. 



■OUADRUEA REEUEGENS (Lea). 



Includes sphccrica (Lea) according to Frierson (41 p. 136). 



QUADRUEA RUBIGINOSA (Lea). 



Unio z'alidus continuus De Gregorio, Moll, di aq. di Amer., 1914, p. 21. 



This species has been identified as the Obliquaria flava Raf. by Say, 

 Conrad and others. According to Vanatta (140, p. 557) the O. flava Raf. of 

 the Poulson collection is this species. If identifiable from the original de- 

 scription, Rafinesque's name would have priority. 



According to Ortmann (78, p. 116) rubiginosa is a variety of undata 

 (Bar.).

 to Ortmann (79, p. 244).
