LYMN^EHXE OF NORTH AMERICA. 463 



Lrymnea lubricoides Lea. 



Lymnea lubricoides LEA, Exp. in Nebraska, Warren's Rep., II, pt. 3, p. 724, 

 1859. 



Limncea lubricoides BINNEY, L. & F.-W. Sh. N. A., II, 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. 



Limnaea palmeri Dall. 



Limncea palmeri DALL, Amer. Journ. Conch., VII, p. 135, 1871. FISCHER 

 & CROSSE, Mis. Scient. Mex., Moll., II, p. 51, 1880. MARTENS, Biol. Cent. Amer, 

 Moll., p. 377, 1899. PILSBRY, Proc. Phil. Acad., p. 777, 1903. 



This species is now referred to the marine genus Recluzia by Dr. 

 Dall.

Lymncea platystoma WHEATLEY, Cat. S'h. U. S., Ed. 2, p. 23, 1845.

This species is the common Lymncea ovata of Europe. The two 

 original specimens in the Philadelphia Academy (No. 58461) are 

 marked "Maine or Marseilles." A single specimen in the Smithsonian 

 Collection (No. 9744) is the same. The specimens were either intro- 

 duced or had become mixed with American shells.

This species is thejmmature form of Otostomus dombeyanus Fer.

Lymncea catascopium var. virginiana JAY, Cat., p. 268, 1852. 



This species can scarcely be American. It was said to be an 

 Asiatic species by Tryon. It seems to be the same as Lymncea spadicea
