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

 vol. 52, p. 361-304, 1909). By Wm. II. Dall. Pleurodonte tenacu- 

 lum and Helfcinn heighwayann are described from the Atrato River, 

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

 Petit, havinf 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 branneri is a new form from the province of 

 Bahia. Brazil.
