This synoptical sketch of the affinities of the different species of 
the Deer tribe expresses much more with reference to the mutual 
relationships of its component members than could be done by the 
employment of the binomial nomenclature. For instance, taking 
the Barasingha Deer, here expressed by Ca’. In that it is of the 
C group, its close affinities to the Sambur, Axis, and Hog-Deer is 
asserted. C being next to B (Elaphine), its not great distance from 
the Elaphine is expressed; whilst, although the Reindeer and the 
Long-tailed Deer have their antlers developed on very similar types, 
the distance of their relationship is signified by their alphabetical 
interval—that between C and P or Q. 
Further, in that Rucervus duvaucelli is represented by Cd’, the 
d proves that there are other genera closely allied to it, namely 
a, b, and c, at the same time that, as there is a figure appended, it 
is to be inferred that there is more than a single species in the genus. 
On the whole, I know no so concise a way of expressing the relation- 
ships of species. 
As to the affinities of the genera here expressed, some are more 
certainly based than others. Capreolus caprea is one of the most 
difficult of the Deer tribe to localize; and I have placed it not far 
from Cervulus on account of the configuration of its glans penis. 
Dama vulgaris, as well as Dama mesopotamica, from the shape of 
their antlers—neglecting the palmation, an evidently insignificant 
character—are intimately allied to the Pseudaxine group; and, as 
the late Mr. Blyth has so satisfactorily demonstrated, there is no 
reason why Eld’s Deer should be in any genus other than that in 
which the Barasingha is situated. The abnormal furcation of the 
antlers of Elaphurus davidianus renders it extremely difficult to place 
that species in any definite position among the Old-World Cervidee.
