12. L. TOGOENSIS Kobelt. PL 21, figs. 23, 24, 25. 



Shell widely perforate, conic-turrite, rather solid, rudely 

 rib-striate and decussate with impressed, unequal spiral lines 

 everywhere except on the lower part of the last whorl ; dirty 

 gray-corneous, very obsoletely streaked and maculate with 

 reddish. Spire conic-turrite, the apex obtuse. Whorls 9-10, 

 convex, parted by an impressed, crenulate suture, regularly 

 increasing, the last shorter than the spire, somewhat inflated, 

 only delicately striatulate below the periphery, compressed 

 into a crest around the perforation. Aperture slightly ob- 

 lique, irregularly oval, somewhat channelled at the base, livid 

 roseate within; peristome simple, acute, widely white-lipped 

 within, the margins slightly connected by a very thin cal- 

 lous; columellar margin somewhat straightened, callous and
