Lymnea lubricoides Lea. 
Lymnea lubricoides Lea, Exp. in Nebraska, Warren’s Rep., II, pt. 3, p. 724, 
1859. 
Limnea lubricoides Binney, L. & F.-W. Sh. N. A., I, p. 71, 1865. 
This species is listed by Lea from Grindstone Creek, Nebraska. 
So far as known, it has not been described, nor are the specimens to be 
found. It is, therefore, a nude name.
