The middle valves of this shell are elegantly fasciated 

 with brown, a light streak runs along the keel, or ridge, 

 with a darker line on each side ; the dorsal triangles are 

 perfectly smooth, but the marginal triangles, and the 

 two extreme valves, are covered with granulated striae, 

 and variegated with brown undulations. The margin 

 scaly, alternately varied with white and green ; inside a 

 glossy verdigrease green. 



This shell varies in colour, being sometimes fasciated 

 with light green, and having a black or dark brown 

 band on each side the dorsal ridge. Inhabits South 

 America. 



The banded Chiton, has been erroneously quoted

 valves will at once distinguish it from the C. marmora- 

 tus, which is entirely smooth.
