1862.] DR. P. L. SCLATER ON THE DEER OF FORMOSA. 151 
sent to Mr. Blyth were of the Japanese species, and that Mr. Blyth 
never had the Formosan species alive*. Mr. Blyth’s comparison, 
therefore, was made between animals of the same species. 
All doubt, however, as to the perfect distinctness of the Formosan 
Deer from the Japanese Cervus sika is removed since we have re- 
ceived the fine male of the Cervus taévanus, presented to us by our 
Corresponding Member, Mr. Swinhoe, in December last. It will be 
evident to any one who inspects this animal and compares it with 
the adjoining specimen of Cervus sika, that, though probably nearly 
allied to the latter and belonging to the same group of Deer, it is 
quite distinct specifically. Its larger size and the deep-red colouring 
of the posterior part of the neck are quite sufficient to distinguish 
it. With the true form of the horns in Cervus taévanus we are not 
yet acquainted, owing to our specimen having broken and worn down 
his horns while in confinement. 
But we have to thank Mr. Swinhoe (who is now Vice-Consul in 
Formosa) for another and most valuable addition to our series of 
Deer. On April 28th, a specimen of what I suppose Mr. Swinhoe 
to mean by the “ Roe-Deer”’ + of Formosa arrived, and is now doing 
well in our Menagerie. It turns out to be a species of the Rusine 
group of Deer, quite distinct from any of the four species of this 
sectiont we at present possess, and in all probability of a species 
hitherto unknown, and for which I propose the temporary designa- 
tion Cervus swinhoii. It would appear, therefore, that there are 
four distinct species of Deer inhabiting the coasts of China and Japan, 
concerning which we require much more information :— 
1. Cervus sika, Temm. & Sieb, (Rusa japonica, Gray), from 
Japan. 
2. Cervus pseudacis, Eyd. & Soul. (Gray, P. Z. 8. 1861, p. 236, 
pl. xxvii.), from Northern China. 
* Mr. Blyth says, “ Mr. Sclater is wrong in identifying the Japanese and For- 
mosan species” (Journ. As. Soc. Beng. 1861, p. 192, note); but he neglects to 
add that my mistake arose from the incorrect information with which he himself 
had furnished me. 
+ Mr. Swinhoe writes to me, “Four if not five Deer are on their way to you. 
The buck (C. taévanus) left me in high condition; and a lovely animal he was. 
The doe of the same species sent was with young; and I have some apprehensions 
about her. The two buck Roe-Deer will, I think, delight the Society, as they 
must surely be new species. 1 did not know of their existence till my visit to 
Taiwanfoo. They are known to the Chinese here as Cheeangs, and are procured 
by them from the aborigines of the inner hills. The C. taévanus, which is pro- 
cured from the same savages, is distinguished as the Lok or Stag; and the Cer- 
ulus as the Kiung. I have seen nothing as yet of the Bear or the Mountain 
Sheep, said to be found in Formosa ; but since my arrival here I have sent a fine 
pair of Monkeys to my friend in Hong Kong for transmission to the Gardens. 
They may turn out novelties, and I have no doubt you would like more; so I will 
try and procure a few more. The Tortoises from Southern Formosa I take to be 
peculiar, and I have accordingly forwarded you a few ; I have also preserved some 
in spirits.” [Those Tortoises have arrived, and turn out to be Emys bennettii, 
Gray.—P. L. S.] wah

moluccensis, ex ins. Moluce.
