LIVING IN THE SOCIETY'S MENAGERIE. 345 
Swinhoe announced that he had forwarded to the Society a “* Mantchurian Deer, appa- 
rently of a new species, procured at New-chwang,” and gave a short description of it 
under the name Cervus mantchuricus. It appears, therefore, that Mr. Swinhoe unwit- 
tingly gave this deer two new names in the same letter. 
Mr. Swinhoe’s typical specimen of Cervus mantchuricus reached this country in safety 
in July 1864', and has since remained with us in good health, though unfortunately we 
have never succeeded in getting a mate for him. 
Plate XXXI. represents this individual in his summer dress, which stage has also 
been described by Mr. Swinhoe (P. Z. 8S. 1865, pp. 1, 2) from a specimen examined at 
Amoy in October 1864. 
Plate XXXII. represents the same individual in the more soberly coloured dress of 
winter, when the spots are barely visible at all, except just on the back, above the 
shoulders.

The Formosan Deer was one of Mr. Swinhoe’s numerous zoological discoveries in the 
little-known Chinese island to which it is confined. In 1860 Mr. Swinhoe forwarded a 
skull of this animal to Mr. Blyth at Calcutta, who described it as C. taiowanus, after the 
Chinese name of Formosa. In December 1861 we received from Mr. Swinhoe a fine 
living male example of this deer, of which animal I gave a notice and figures in the 
« Proceedings’ for 1862 (p. 150, pl. xvi.). In 1866 we received through Mr. Swinhoe 
our first female of this species; and in 1868 (July 21) the first fawn was born, which is 
represented with its mother in Plate XXXIV. as it appeared in November of that year. 
This Deer, however, has not done nearly so well with us as the following species, 
C. sika. 
Mr. Swinhoe has given some details respecting the habits of this Deer in his article 
on Formosan Mammals published in the Society ‘ Proceedings’ for 1862 (p. 362). 
I think it probable that the Cervus pseudaais of Eydoux and Souleyet (Voy. Bonite, 
Zool. p. 64, pl. 3), established upon a living animal obtained by these naturalists in 
Java and brought to the Jardin des Plantes in 1838, was of this species; and if this be 
case, the name pseudaais has priority over taévanus. M. Pucheran informs us’ that 
another individual of this species was obtained by the expedition of the ‘ Astrolabe’ and 
‘Zelée’ at the Sooloo Islands; but this, as well as the former example, may have been 
carried away in ships from their native land.
