Strophocheilus (Boeus) indigens, n.sp. 



Shell ovate-oblong, yellowish-brown, moderately solid; spire about 



13 mm. longer than the aperture ; whorls 6^, apex smooth, the second 



and third whorls with prominent oblique plications, last two volutions 



polished and apparently smooth, but under the lens are seen to be 



Reduced about ^. 



finely granulated, the granulation being strong on the middle whorls, 

 and gradually becoming weaker towards the aperture, the lower 

 whorls have also some irregular and almost obsolete plications ; 

 aperture sub-oval, whitish within ; peristome thickened and very 

 slightly expanded, white, margins joined by a moderately thickened 

 white callus. Alt. 110, diam. maj. 47 mm.

The nearest species to this is S. {Borus) huascari, Tschudi, which is 

 broader, has a wider aperture, a rougher and duller surface, and its 

 apical plications are much finer and closer together than in indigens.
