The only journal in America for the study of the Mollusca is 

 the Nautilus, published by Dr. H. A. Pilsbry and Dr. H. B. Baker, 

 the Academy of Natural Sciences of Philadelphia. It begins with 

 Volume 3, 1889, and has completed 52 volumes to 1939. Records 

 and notes on many Illinois species of land snails have appeared in 

 its pages; it is considered indispensable for the study of Illinois 

 Mollusca.
