Pfeiffer notices two color-forms, one with the shell dark 

 brown, marbled and dotted with whitish, the other whitish 

 dotted with corneous, with a chestnut band below the keel. 

 One of this pattern is represented on pi. 23, fig. 64, from 

 Yateras, the type locality, where it occurs with streaked 

 specimens. There seems to be always a chestnut band within 

 the umbilical cavity. The shell is more widely conic than 

 M. canimarensis.
