^ Dr. Kindle's Bulletin on the Onondaga Fauna of the Allegheny Region has 

 appeared since the following description was in type. It then appeared to the 

 writer that perhaps part of these specimens might be referred to Dalmanella 

 lenticularis ("Vanuxem) and the figured ones were sent to Dr. Kindle, who 

 wrote December 17, 1912, that those from Ernstville and Hanging Rock, "W. "Va., 

 " represent D. lenticularis in my judgment and doubtless came from the beds I 

 have referred to the Onondaga." On the explanation of Plate XIV the names 

 for the specimens from these two localities have been changed to Dalmanella 

 lenticularis ("Vanuxem). Dr. Kindle also wrote that " The specimen numbered 

 4940 [from "Williams Road] I would identify as you have Indicated as Rhipi- 

 domella cydlas ? Hall."
