The variations in colour are fully described by Strebel 1! ; the ground-colour is either 
white or pale yellow, and there are ordinarily five reddish-brown bands, which are 
either continuous or interrupted into rows of spots, or also very pale with darker spots. 
The lower bands are mostly continuous. The uppermost or the two upper bands are 
absent in several specimens; if also the third is wanting, we have the variety 4, 
hypozonus, which, however, is ordinarily of a more ventricose form. Many young 
specimens show only the two lower bands. The two and a half upper whorls are 
finely cancellated. 
Strebel states! that this species is often found on a shrub called “ huichin,” which 
bears umbels of 40-50 yellow flowers (capitula ?), and belongs to the natural order
