The arrangement of the colors on this eel is suggestive that the back and 

 upper surfaces are exposed to the more direct rays of light; these portions of 

 the body are dark while the lower half is much lighter and even white. Further, 

 the chin and throat are much darker than the balance of the lower surfaces, 

 which is probably due to the habitual carriage of head and neck raised above 

 the horizontal. 



Washan; from a marsh near the Tung River, at an altitude of 6,000 feet 

 or more.
