Omphalina fuliginosa ozarkensis Pilsbry and Ferriss, Proc. A. N. S. Phila., 

 1906, p. 562. 



Shell similar to that of 0. cuprea. Soft parts differing by having 

 the branches of the vena cava in the lung intensely black-pigmented, 

 showing through the shell in life. Epiphallus inserted midway on 

 the penis, not distally as it is in 0. cuprea.

 Cotypes No. 91,348 A. N. S. P., collected by Ferriss and Pilsbry, 

 April 1 and 2, 1903. Also on the north side of the summit of Maga- 

 zine Mountain, Logan County, Arkansas, March 28 to April 2, 1903, 

 and Sugarloaf Mountain, on the Oklahoma boundary. 



I can find no differential characters in the shells of this race, though 

 the microscopic striation and obscure granulation may be a trifle 

 more distinct than in cuprea; but the anatomical characters seem 

 so diverse that a special race is indicated. In the field it was at
