 abrupto), in medio aliquanto angulati, superne ad suturam oblique 

 brcviter lirati vel crenulati, costis medio subacute angulatis, su- 

 perne suturaa vix attingentibus (in anfr. ultimo ad 12 fere basi 

 continuis) liris elevatis spiralibus (in anfr. superioribus 2-3 in 

 ultimo 15-lG supra costas nodosis) clathrati ; apcrtura alba, 

 longitudinis testae ^ jequans ; columella rectiuscula, callo crasso

 few brownish spots scattered here and there on the upper
