152 _ DR. G, HARTLAUB ON TYLAS EDUARDI. [May 13, 
3. Cervus taévanus, Blyth (Journ. A. S. B. xxix. p. 90), from 
Formosa (Pl. XVI.). 
4. Cervus swinhoii, sp. nov., from Formosa (Pl. XVII.). 
Our single male specimen of Swinhoe’s Deer stands about 
2 feet 8 inches in height, and presents the general appearance of a 
small Deer of the Sambur group (Rusa). The head, neck, and fore 
legs are greyish black, growing more rufescent on the back, and 
passing on the rump and hind-quarters into a deep chestnut. The 
tail is rather long and very bushy, and composed of grizzly blackish 
hairs. ‘The inside of the thighs and belly beneath are fawn-colour, 
passing on the inside of the legs into pale ochraceous. The animal 
appears to be in about its second year. The present horns have 
been injured whilst growing, and are much broken.

We have named this interesting new form after its discoverer, 
Mr. Edward Newton, a gentleman who has recently visited Mada- 
gascar, and whose zealous efforts have very materially forwarded our 
knowledge of the ornithology of the East-African Archipelago. 
The genus Ty/as is nearly allied to Hypsipetes, but differs in the 
beak being decidedly stronger, broader, and more inflated; in the 
-longer wings, which in Hypsipetes do not reach to the middle of the 
tail; in the tail being proportionally shorter; and in the rictal 
bristles being much more developed. The under tail-coverts are very 
long. The iris is yellow—a colour not found hitherto in the genus 
* rudads, “avis quedam ignota turdina.”
