It was purchased of one of the London dealers in February 1879, and was originally considered an immature example of Chrysotis dufres-niana, to which species it is most nearly allied. But it has remained without material change since its arrival, and a closer examination leads me to believe that it is not an immature bird. I therefore propose to describe it as follows :- CHRYSOTIS CCELIGENA. (Plate IX.) Clare viridis, fronte flavida, facie tota utrinque cyaneo lavata ; speculo atari aurantiaco; caudce apice flavicante; crassitie paulo minore quam in C. dufresniana. In Vivario Soc. Zool. Lond. Obs. Similis C. dufresniance, sed genis cseruleis, fronte non rubra, speculo alari flavo et cauda nullo modo rubra distinguenda. The bird described by Dr. Finsch (Papag. ii. p. 532) as the young of G. dufresniana is probably this species. Singularly enough I have just received (this morning, Feb. 17th) a box of skins for examination from Mr. G. N . Lawrence of New York, amongst which is a single example of this Parrot, obtained "on the Essequibo river in the winter of 1875-76, by Mr. A. H. Alexander, of West Hoboken, New Jersey." Mr. Lawrence gives to it the name "cceligena'" in his paper (to be published in 'The Ibis'), which I adopt with pleasure instead of the name I had intended to propose for it. Mr. Sclater called attention to the fact that Colobus palliatus, Peters, Monatsb. Ak. Berlin, 1868, p. 637 (recently figured, Monatsb. 1879, p. 830, tab. iv. A ) , of which he exhibited a specimen, seemed to be identical with Colobus angolensis, Sclater, P. Z. S. 1860, p. 246. Mr. Sclater had compared the type of his C. angolensis, a flat skin now in the British Museum, with a fine adult specimen from the Pangani river-valley on the Zanzibar coast, in the same collection lately received from Dr. Kirk, which was doubtless Colobus palliatus of Peters, and had found them to agree in nearly every respect, except that the Zanzibar example showed rather more white on the throat. The skin of Colobus angolensis, which was brought by Mr. Monteiro from Angola, might have travelled a long way from the interior of the continent; but it was certainly singular to find it identical with a species of the eastern coast. The Secretary read the following extract from a letter addressed to him by Mr. W . B. Pryer, dated Elopura, Bay of Sandakan, Borneo, 27th October, 1879:- "I nearly always have some half dozen different birds and animals about the house, and should be glad to send them to Singapore, on account of the Society, if you have any one there to receive and forward them. Amongst the specimens Monkeys take a leading place ; but I presume these are not particularly required; the two species of |
