Planorbis sinuosus Bonnet. 



Planorhis sinuosns Bonnet, Rev. & Mag. Zool., 1864, p. 280, pi. XXII, fig. 3. 



Type locality : New Mexico. 



Is referred to glabratus Say by Tryon (129, p. 183). Fischer and 

 Crosse (38, p. 67) question this approximation, but as their opinion is 

 based on Binney's figure (11, fig. 179), which does not represent Say's 

 species, it is not of much value. However as glabratus is not known to 

 occur outside of Florida, Tryon's suggestion is wrong anyway. Dr. Pilsbry 

 informs me that it is P. tiuiiidiis Pfr.
