mens furnished by our conchological forefathers, and no localities 

 more definite than the States mentioned have been given. It may be 

 that the eastern range claimed for this species and Polygyra dorfeuilli- 

 ana will prove to be without foundation in fact. In the West its 

 actually ascertained range is as foUows. Except where otherwise 

 stated, we have examined specimens from the localities mentioned : 



Missouri: Camden, Benton, Macdonald and Jasper counties;" 

 Springfield, Green Co. ;^^ Marble Cave near Galena, Stone Co. ; Seligman, 

 Barry Co.; Chadwick, Christian Co.; Cedar Gap, Wright Co." 



Arkansas: Mammoth Spring, Fulton Co.; Eureka Springs, Carroll 

 Co.; Rogers, Benton Co.; Van Buren^^ and Chester," Crawford Co.; 

 Washington,^^Franklin,^^Conway,^^Perry,^^and Independence^^ counties ; 

 Carrion Crow Mt.," Pope Co.; Hot Springs, Garland Co.; Washita 

 Springs,^^ Montgomery Co. ; Little Rock, Pulaski Co.; Magazine Mt,, 

 from the summit down, and Petit Jean Mts., Logan Co.; Poteau Mts., 

 south of Gwynn P. 0., Hartford Sta., Sebastian Co. 



Indian Territory: Sugar Loaf Mt., northwest of Gwynn P. 0., Ark. 



These localities are all in the hilly or mountainous country, chiefly 

 in central and western Arkansas, barely reaching over the State 

 border on the west, but extending some distance north into Missouri. 

 Nowhere does the species approach the lowlands of the Mississippi, so 

 far as we know at present; but we are still practically without data on 

 the land moUuscan fauna of eastern Arkansas. 



In his original description Bland mentioned four localities for P. 

 labrosa: Washita Springs and Hot Springs, Ark., Tennessee and Ala- 

 bama.' As neither was designated as typical, I would suggest that 

 Hot Springs, Garland Co., Ark., be selected as the type locality. It 

 has been collected there by Ferriss and others. 



There is a Helix labrosa of Wood, Index Testaceologicus, Suppl., p. 24, 

 pi. 8, fig. 69 (1828), which seems to be identical with Buliminus labiosus 

 Mull. 



P. (Stenotrema) edgariana might be supposed to inhabit Arkansas, 

 from the range given by Binney, Man. Amer. Land Shells, p. 275, but 

 it has not to my knowledge been found west of the Mississippi River, 

 and I doubt its occurrence there.
