form, white within ; peristome somewhat expanded, the right

 dermide fulva, nigro-strigata vestita ; spira conica, obtusa ; anfr. 5 1-2, infla- 

 tis, ultimo spira paulo breviore, basi rotundato ; apertura fere diagonali, 

 late auriformi, intus alba ; plica columellari crassa, dentiformi ; perist. intus 

 labiato, margine dextro recto, substricte descendente, leviter antrorsum

This shell may be classed with the lorata group, although it 

 has a large variety of color and form.
