somewhat resembles shimekii. The specimens collected by Dr. 

 Leighton are slightly smaller than specimens from the Iowa locali- 

 ties. 



Oreohelix iowensis (Pilsbry). Fragments of a large land shell 

 in the Peorian loess near Peoria are believed to be this species. 

 This fossil has been reported several times from Illinois deposits, 

 and as it is a characteristic loess fossil, it may be of value to list 

 these localities for comparison. 



Virginia, Cass County (listed as Helix strigosd), Sangamon loess (Leverett, 



p. 171). 

 Fulton, Whiteside County, Peorian loess (McGee, p. 448). 

 Savanna, Carroll County (Chamberlin & Salisbury, p. 285), driftless area. 



(See Baker, Life of Pleistocene.) 



Euconulus fulvus (Miiller). A single specimen occurred in 

 each of two deposits, in loess, Whiteside County, and in peat, 

 Carroll County. Both are typical. 



Vitrea rhoadsi Pilsbry. Two specimens of this little snail 

 occurred in the peat deposit in Carroll County. They were appar- 

 ently typical. 



WABASH DEPOSITS IN THE VALLEY OF THE ILLINOIS RIVER 



Mr. Harold E. Culver, geologist of the State Geological Survey, 

 recently obtained a very interesting collection of molluscan material 

 from marl deposits in Grundy County. Mr. Culver has furnished 

 the following information concerning this deposit and its relation 

 to the associated strata: 



The shells from the marl deposit were uncovered in coal stripping opera- 

 tions near Morris, Illinois. The pit is located in the S.E. quarter of sec. 34 of 

 Saratoga Township (34 N., 7 E., 3d. P.M.).
