 ANNOTATED LIST OF ALABAMA LAND MOLLUSCA. 



BY F. E. SARGENT, WOODVILLE, ALA. 



Those familiar with the scarcity of land mollusca in the northern 

 prairie States will appreciate the pleasure which one experiences in 

 coming from Minnesota to Northern Alabama. 



With headquarters upon the top of Cumberland Mountain in 

 Jackson Co., it has been my pleasure during the past five months to 

 do some collecting of land mollusca, the result of which may be of 

 interest. The topography of the region is quite varied. The 

 summit of the mountain is comparatively level, rather sandy and 

 covered with timber. About half way down we come to the 

 " benches " which are covered with lime-rocks. In most cases the 

 flat rocks are piled one upon another forming excellent retreats for 

 the smaller forms. At the foot of the mountain the " coves " are 

 level and in places covered with heavy open timber. 



The following list is doubtless far from complete, as but a small 

 portion of the region outside of a radius of two miles from Wood- 

 ville has been searched. 



1. Selenites concava Say. Large form. Common, mostly on 

 benches. 



2. Zonites fuliginosus Griff. Frequent on benches. 



3. Z. Ifevigatus Pfr. Common on benches. 



4. Z. ligerus Say. Large form. Few very fine. 



5. Z. intertextus Binn. Few on toj). 



6. Z. arboreus Say. Common on top. A peculiar form with 

 strong striation above.
