308 DRYM^EUS, SOUTH AMERICAN. 



Strebel has figured (pi. 50, figs. 96, 97) slender specimens from 

 Tequendano, Ecuador (Dr. Reiss), and he also reports the species 

 from Tacatativa, on the Bogota plateau (v. Nolcke). The specimens 

 from Tequendano, show variation in the bands, in some examples 

 bands 1 and 3, or only 1, or 1, 2, 3, 4 being obsolete. They appar- 

 ently belong to the slender variety elongatulus.

 pressed above, then lightly arcuate. Aperture oval-oblong, colored 

 within like the outside ; peristome simple, straight, right margin

The species reported by von Martens as Bulimulus fidustus in 

 Jahrb. d. D. Mai. Ges., iii, 1876, p. 258, was probably different.
