TEEEKKA INORNATA, 11. sp. 



Plate XX, figs. 11-13. 



Shell below niediuni size and very slender, consisting of twelve or 

 more \-olutions; spire attenuated; volutions sloping abruptly for about one- 

 third of their exposed surface below the suture, below which point their 

 sides are vertical, parallel, and destitute of ornamentation other than tine 

 lines of growth, except on a few of the apical volutions; where, when })er- 

 fect, there are faint vertical ridges; aperture narrow, elongate, forming 

 about three-fifths of the height of the body volution at its margin; outer 

 li]) thin and shari); columella twisted, slightly excavated on its face, and 

 marked by a thickened spiral rib near the base; channel slight. 



A number of this species have been obtained, but are mostly corroded 

 and dissolved liy the action of water, so that all the upper vt)lutions 

 have been destroyed; in which condition they are more rapidly tapering 

 and present a less number of volutions. In fact most specimens present 

 none of the original suriace, except on the lower one or two volutions. It 

 diifers in its surface characters from any known species, in the sloping of 

 the upjier third of the exposed part of the volution, and the vertical space 

 lielow, and iu want of ornamentation.
