SMALL LAND MOLLUSCA FROM NEW MEXICO. 



BY DR. V. STERKI. 



A few days ago, Mr. Theo. D. A. Cockerell kindly forwarded me 

 some small and minute shells of Mollnsca collected in drift on the 

 Rio Grande, at S. Marcial, N. M., with the request to publish a list 

 of them with notes. The species were the following : 



Hyalinia minuscula Binu. 



Helicodizcus lineatus Say. One example. 



Vallonia costata Mull. One example ; this find is of peculiar in- 

 terest. 



Vallonia cyclop horella Anc. Rather small form ; a few examples. 



Pupa fa/lax Say. 



Pupa arizonensis (Gabb.) W. G. Binney. 



Pupa hordeacea Gabb. Rather small ; variable in size and color. 



Pupa procera Gould. One example, light colored. 



Pupa hordeacellit Pilsb. Light colored to glassy transparent. 



Pupa pilsbryana Sterki. One example; slightly more striated 

 than those previously seen. 



Pupa blaitdi Morse. A few ; light color to colorless. 



Vertigo ovata Say. Two specimens, rather typical. 



Besides these, there were a few examples of Limnrea and Plan- 

 orbis.
