tenuissime longitudinaliter substriata; spira obtusa, lateribus convexis; aper- 
tura oblonga; labio antice rotundato, reflexo; labro postice valde sinuoso, 
in medio inflexo, peritremate incrassato. — The posterior tooth of the inner 
lip is elongated, the middle tooth double; in the outer lip three ofthe teeth 
are prominent, the two posterior being approximated; the umbilicus is partly 
closed by the reflection of the inner lip. (A. Adams l. c.) 
**) S. testa ovato-pyramidali, laeviuseula, rufo-castanea, longitudinaliter 
vix striata, anfractibus convexiusculis semisuleatis, fascia nigricante prope 
suturam; apertura subrotundata, labio crasso, antice rotundata, dilatata; 
labro semicireulari, postice subsinuato. — -A pyramidal, smooth, dark- 
brown shell, with the whorls strongly suleated longitudinally near the sutu-

the inner lip is rounded and thickened in front; the umbiheus is large and
