Shell broadly ovate, rather solid, ground color milk-white, the spire 

 being usually covered •with the merest indication of a film of periostra- 

 cum, while the basal portion is much more strongly provided with this 

 element, which here forms a thick olivaceous-yellow coating. In addi- 

 tion to this there are various spiral bands varying in color from bright 

 chestnut-brown to brownish black. These differ in number both on 

 spire and base. In most instances we have a single broad band, almost 

 median between summit and spire, winch begins on an early whorl as a 

 slender bright chestnut-colored line and gradually becomes intensified 

 in coloration until it may be almost black. This band is frequently 

 flanked with a narrower one posterior to it. Sometimes the two are 

 both broad and separated by a mere lighter line; sometimes, too, there 

 is a broad band of brown immediately below the summit of the shell. 

 The base is far more variable in its ornamentation than the spire. It
