 Physa (Thomsonia) carinifera Ancey, Le Nat., 1886, p. 358. 



Type locality : Everglades of Florida.

PivANORBis siNuosus Bonnet. 



Planorbis sinuosus 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 glabratns is not known to 

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

 informs me that it is P. tumidus Pfr. 



Planorbis subcrlnatus disjlctus Cooper. 



Planorbis subcrenatus disjectus Cooper, Pr. Cal. Acad. Sci., (2) III, 1890,
