" This species is remarkable for its flat, disk-sbaped expanded 

 peristome, usually of a bright orange or scarlet colour, and for 

 the absence of marked sculpture, and, in most specimens, of any 

 conspicuous coloration, except a single broad dark chestnut stripe 

 below the periphery." (JUanford.)

Blanford refers to the fact that Theobald classes C. patens as a 

 WLviety oi. C. fidgiiratus, but does not agree with this view. He 

 states that both occur together at Thayet Myo and are very 

 distiuct, C. patens having a broad, rather thin disk-like expanded 

 peristome, while the lip of C.fuh/urams is much thicker but only 

 moderately ex|)anded. The former also is much smoother.
