 Mercer Co. (Marsh) and from the Kishwaukee River (Hinkley 

 and Marsh). Simpson (Synopsis, p. 539) makes this a synonym 

 of ventricosa. 



* Lampsilis propria Lea. A specimen of this species, identified by Mr. C. T. Simpson, 

 is in the collection of the Chicago Academy of Sciences and was received from 

 Mr. W. W. Calkins as from the Illinois River. As this species has been found 

 only in Virginia and Georgia the Illinois record must be considered very doubt- 

 ful. The probability is that the specimen became mixed with Illinois shells.
