the colour is described as with streaks or clouds of blue, yellow, 

 and green, varied by reflections of violet, on a dusky ground; 

 iris golden yellow, the pupil blue; and the surface of the body

 wood or ivory; and when examined with a lens, in our example 

 these rhomboid plates appear to be studded over with dots of 

 a marble substance, but with little roughness of texture.
