Besides skins of this species of stag, I find, in Mr. Darwin’s collection, three 
pairs of horns, which, together with a pair belonging to one of the skins, consti- 
tute a sufficiently complete series to illustrate the different forms which these 
appendages assume, as the animal increases in size. 
The above four sketches, which are all drawn to the same scale, will help to 
convey a clear idea of the forms, and relative proportions, of these horns. 
The most simple horn (fig. I.) consists of a beam , eight and a half inches 
long, which is slightly arched outwards and considerably compressed about two 
and a half inches from the apex. At one inch from the base there is a small brow 
antler which projects forwards and upwards. 
In the next horn, (fig. 2.) there is the same small brow antler, but there is a 
single small snag , about equal in size to the brow antler, which is directed back- 
* Figures 47 and 48 of M. Cuviers work represent horns so unlike either of those brought over by Mr. 
Darwin, that I cannot help suspecting they belong to some other species of stag. 
Scale of twelve Inches.
