Obs. The above description is taken from the faded Poole specimen, aided, as regards the tints, by a reference to the 

 Bengal and Japanese skins*; the distribution of colour is the same in each, and so are the tints, as can be seen 

 by looking at those parts which happen to have kept their colour in the first-named example. 



'* These are the only three examples I can trace anywhere in England. The species is wanting in the British Museum ; 

 aud there is not a single specimen in the immense collection amassed by the late Marquis of Tweeddale, and now in the 

 possession of Capt. Wardlaw Bamsay. The Bengal and Japanese examples are in Mr. Seebohm's museum.
