550 MR. P. L. SCLATER ON CERTAIN SPECIES OF DEER 
turned out to be a species of the Rusine group, which I subsequently described in the 
Society's ‘ Proceedings, and proposed to call Cervus swinhoti after its discoverer. The 
figure given along with the description (P. Z. S. 1862, pl. xvii.) represents this indi- 
vidual shortly after its arrival, when its young horns were growing. The accompanying 
Plate, copied from a sketch by Mr. Wolf (Pl. XX XIX.), shows the adult form of the 
animal. 
In September 1862 we received a second young male of this Deer, and in September 
1867 a third example, which, at the moment, we believed to be a female and was so 
entered in the register!. This, however, was subsequently discovered to be unfortu- 
nately an error, as the individual turned out to be a young male, which has since 
developed horns, and is still living in the Gardens. 
Mr. Swinhoe has given us an account of the habits of this Deer in a state of nature 
in his article on Formosan Mammals (P. Z. $. 1862, p. 364). 
As regards the affinities of this species, it is unquestionably nearly allied to the 
Figs. 7 & 8. 
Cervus aristotelis. 
Cervus equinus of Sumatra and Borneo (ef. Miiller, Verh. Zool. p. 212, tab. 42); and I 
do not pretend to be able to point out the differences between these two Deer, as we 
' See P. Z. S. 1867, Appendix, p. 1046.
