OuADRULA pusTTjLOSA pernodosa (Lea). 



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

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

 iicxitosa hullata Raf. and Lea's name will stand.

Unio plcnus intcrduos De Gregorio, IMoll. di aq. dul. di Amer., 1914, p. 18. 

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

 \'anatta 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.

Unio validus continuus De Gregorio, Moll, di aq. di Amer., 1914, p. 21. 



This species has been identified as the Obliquaria Hava 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.

 (Bar.).
