Shell cylindric, the upper third conic; somewhat trans- 

 parent tawny-olive, with an opaque whitish more or less swol- 

 len tract behind the lip ; rather closely regularly striate. An- 

 gular lamella strongly thickened on the right side where it 

 joins the peristome, a short, deeply placed lamella (spiral 

 lamella) beyond its inner end. Columellar and subcolumellar 

 lamelke subequal, remote from the peristome; the supracolu- 

 mellar small and almost immersed or wanting. There are 4 

 long, conspicuous plica?, the lower palatal slightly longest and 

 penetrating to the mid-dorsal line ; upper palatal nearly or 

 quite as long; the interpalatal and basal plicae are shorter 

 within ; deep within a short suprapalatal or sutural plica may 

 be seen ; all of them are conspicuous externally as light lines. 

 Lip is reflected, thickened and whitish, preceded by a low 

 crest or hump. 



Length 7.7, diam. above aperture 3 mm.; 9 whorls (Lyons).
