Some New South American Land Shells (Smiths. Misc. Coll., 

 vol. 52, p. 361-364, 1909). By Wm. H. Dall. Phurodonte tenacu- 

 lum and Helicina heighwayana are described from the Atrato River, 

 Sierra Darien. The former seems closely related to P. uncigera 

 Petit, having a remarkable hook within the basal lip, like that species. 

 The altitude of the shell assigned (6.0 mm.) must be a typographical 

 error. Odontostomus hranneri is a new form from the province of 

 Bahia, Brazil.
