a waved longitudinal direction over the tubercles.

This beautiful species described by Lamarck as being 
vulgarly called the ‘Persian vest’ is still one of great” 
rarity ; it is of a buff or reddish-orange mottled with white, 
and the interstices between the grooves are more or less 
marked with obtuse swollen tubercles.
