Of four specimens from Nyasaland only one has the two pale rosy 

 bands of the type. Martens describes the four apical whorls as 

 uniformly yellow, whereas all the specimens I have examined have 

 in these whorls a black zone just above the suture.

Allied to B. usagaricus Smith, but thinner, yellower, with a 

 narrower perforation and a differently reflexed columella. I cannot
