" This form is a representative here of tlie Ceylonese C. hairdii. 

 A varie^y of the same size but plain, -with pale band on the 

 periphery, on Toriiputu Peak. Small (major cliam.0-65[16"5mm.]) 

 varieties also occur, both ornamented and plain ; the latter are 

 very similar in size and light ochreous colouration to C. ravidus of 

 the Nilgiri Mills, but the former have fine zigzag markings and a 

 single black band on the periphery." {Oodiuin- Austen.)
