a fine opportunity is offered for comparison. The deep red colouring 
of its hind neck and its larger size distinguish it from that species, 
as well as the form of its horns, which are shown in the accompanying 
sketch. (See woodcut.) The white spots on the Formosan Deer are 
moreover lasting, and do not disappear in winter, as in most species. 
This Deer is called by the Chinese Lok, or Stag.

‘‘the four-eyed.’’ It is, however, more generally known in Formosa 
as the “‘Cheeang.”’ What the horns of this Deer are like we shall 
not be able to tell for some months, until the animals in the Gardens
