Most of these determinations must be received as doubtful or 

 provisional, as specimens are imperfect. 



The collection from Caudevalito contains only one or two 

 fairly well preserved shells, the others are indeterminable, and on 

 the whole I would rather not say anything about them (except 

 that they appear to be of tertiary age) pending the receipt of 

 more and better specimens.
