200 I'UOCEEDINGS OF THE ACADEMY OF [Feb., 



received from Mr. A. G. Wetherby, and from Chattanooga, collected 

 by Mr. S. N. Rhoads. At the latter place it coexists with a heavy 

 form of albolahris, though the two do not occur together. 



Polygyra albolabris fuscolabris nov. 



Finally, near Woodville, Jackson county, in northern Alabama, a 

 form was collected several years ago, by J\Ir. H. E. Sargent, which 

 seems to be the culmination of the alleni type, with some special 

 features which make it advisable to treat it as a local variety, under the 

 new name P. albolahris fuscolabris. The shell is very large, alt. 19, 

 diam. 34 mm., to alt. 21, diam 38 mm.; depressed, glossy and finely 

 striate, as in alleni with the aperture more oblique and the lip nar- 

 rower than in albolabris of the same size. The basal lip bears a low, 

 flat-topped, wide tooth near the columella, and the outer lip is tinted 

 fieshy-brown (fading in cabinet specimens). Whorls 5^. 



This particular form is yet known from Mr. Sargent's collections 

 only. A large, heavy form of P. albolabris, probably referable to var. 

 major, also occurs near Woodville. P. a. fuscolabris bears such a rela- 

 tion to alleni as major to albolabris, or var. normalis to typical P. 

 anclrewsce. 



Polygyra zaleta Binn. (ccokln Binn.). 



Seligman, Barry county, Mo. Small specimens, 20-22 mm. diam. 

 It is in the collection of the Academy from two other localities in 

 Arkansas : Eureka Springs (F. A. Sampson) and ^tlabelvale (C. W. 

 Johnson). 



Polygyra indianorum tPilsbiy). 



P. divesta indianorum Pils., Nautilus, XIII, p. 39 (August, 1S99). Ferriss, 

 Nautilus, XIV, p. 28 (July, 1900). 



Tushkahoma, Choctaw Nation, I. T. Five specimens 25^ to 28 mm. 

 diam.; also Standley,* I. T. Further experience with this form con- 

 vinces me that it is quite distinct from P. divesta; a course prompted 

 by Mr. Ferriss. As he has collected and examined more specimens 

 than any one else, T am the more disposed to depend upon his judg- 

 ment. 

 Polygyra divesta (Old.). 



Pilsbry, Nautilus, XIII, p. 38 (1899). 



Chadwick, Christian county, and Seligman, Barry county. Mo. 

 In Ai'kansas at Chester, Crawford county; Petit Jean, Yell county; 

 Hot Springs, Garland county; Carrion Crow Mountain, Pope county. 

 There is but little variation in the specimens from Ai'kansas, all of 

 which are typical. At Seligman, in southwestern Missouri, the size
