486 CERVUS. 
Such a position of the first branch may be observed 
amongst existing Deer, in the great Rusa, or Hippelaphus 
of India, and in the Mazama or Cervus furcatus of S. 
America ; but it is always directed more obliquely upwards 
‘than in the fossil. The Cervus Guettardi, amongst fossil 
species, shows the same relative position as well as di- 
rection of the first branch ; but this species is smaller than 
in the Kirkdale fossil, being intermediate between the 
Rein-deer and the Roe; and the beam is smoother and 
less cylindrical. The British extinet species would seem, 
however, to be more nearly allied to the fossil of Etampes * 
than to any known existing Deer; but it is distinct, and 
I propose to dedicate it to the distinguished Geologist by 
whom its chief characteristic was first pointed out.
