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 Mollusca 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 minuseula Binn. 
Helicodiscus lineatus Say. One example. 
Vallonia costata Mull. One example; this find is of peculiar in- 
terest. 
Vallonia cyclophorella Ane. Rather small form; a few examples. 
Pupa fallax Say. 
Pupa arizonensis (Gabb.) W. G. Binney. 
Pupa hordeacea Gabb. Rather small; variabie in size and color. 
Pupa procera Gould. One example, light colored. 
Pupa hordeacella Pilsb. Light colored to glassy transparent. 
Pupa pilsbryana Sterki. One example; slightly more striated 
than those previously seen. 
Pupa blandi Morse. A few; light color to colorless. 
Vertigo ovata Say. Two specimens, rather typical. 
Besides these, there were a few examples of Limnea and Plan- 
orbis.
