''At first sight this species much resembles 0. jonasi; in 0. auri- 

 fluus, however, the yellow stripes are on the same level as the whit- 

 ish ground, whereas in 0. jonasi the pale brown stripes are placed in 

 depressions between the elevated whitish plaits. The edge of the 

 aperture is also distinctly expanded in 0. aurifluus, but only in full- 

 grown specimens. The locality, 'Vera Cruz,' quoted by Dr. Pfeiffer, 

 is probably intended for the State of that name, not the town."
