Ori(/inal description : — " Testa couoidea, obtecto-perforata, 

 carinata, tenui, polita, albida, translucente, sub epideruiide pallida 

 straniiuea et decidua lineis exilissimis flexuosis spiraliter ornata. 

 Anfraetibus 4|, oeleriter crescentibus, ad apicem mainniillatum 

 paulo convexis, sed ultimo supra planato et circa unibilicuni paido 

 intlato. Apertura magna subquadrata ; marginibus simplicibus 

 calio tenuissimo junctis. 



"Diam. maj.25-4, miu. 19'5, alt. l-i-8, aperturae alt. 16, ejusdem 

 lat. 14 mm." {Theobald.)

As Prof. Pilsbry correctly observes : "judging from the sharp lip, 

 as well as the locality, this is no Corasia. It may prove to be a 

 Nanina." Pending further information he, however, considered it 

 advisable to retain it tbere, although in a'^oI. is of the Manual of 

 Conchology he does not include it in the genus. Its position is 

 veiy uncertain, and it is not at all improbable that the thin, 

 sharp, peristome is an indication that tlie specimens are not full- 

 grown. I was at first inclined to regard it as a member of the 

 genus Euplecla, but the elevated conoid spire and its superficial, 

 incised, close, wavy spirals — so totally different from the sharply 

 cut, decussating spirals to be observed in that genus — are features 

 which do not, I consider, permit its inclusion thei-e. The texture 

 of the shell rather approaches that exhibited by the subgenus 

 Bcddomea and I, therefore, propose to place this new genus 

 provisionally next to uimphidromus.
