My dear Sir,
I have just returned from the country, and been engaged in unpacking some of the bones from Formosa—1In the large collections I have made I have many things that confirm your theory of species which I will bring to your notice so soon as my series are arranged.2 At the present my chief object in writing to you is to forward you a specimen of the ordinary domestic Pigeon of China. It is unfortunately somewhat albino, but in form and proportions it is quite typical of the bird reared in the dovecots of China—3
I have further a remark to make regarding Anatidae— you questioned me some time ago as to whether the hybrid between the Muscovy and Chinese domestic Duck ever interbred.4 Notwithstanding what Pallas states to the contrary in his Zoograph—Ross—Asiat.5 I am confident that a thorough race has been produced between these two species, which though constantly bred in and in still preserves its characters, viz those of being much larger than the common chinese Duck, and of having the legs placed more central under the belly giving it a more goose-like appearance. This race has a smooth head, never wattled, and is usually black, has in Amoy (China) the name of Aw-ah or Black Duck, as distinguishing it from the Ah or Duck proper and the Liengtasu ah (Dragon-headed Duck) or Muscovy.
I remain, | Your’s very truly, | Robert Swinhoe
P.S. The Pigeon is from Foochow. (Foochow)6
