502 ON A COLLECTION OF BIRDS FROM BORNEO. [JunC 23, 



I June 23, 1887. 



Prof. W. H. Flower, LL.D., F.R.S., President, in the Chair. 



Mr. Sclater laid upon the table the skin of a White-nosed Mon- 

 key of the genus Gercointhecus, which had been presented to the 

 Society's Menagerie by the Rev. W. C. Willoughby, December 9, 

 1883, and had died on the 13th November last year. 



Mr. Sclater had now ascertained I'rom Mr. Willoughby that 

 this specimen had been obtained by him in Unyamwezi, Eastern 

 Equatorial Africa, and was said to have been brought from Man- 

 yuema, on the western shore of Lake Tanganyika. It was un- 

 doubtedly different from the ordinary form of O. petaurista of 

 West Africa, hitherto received by the Society, and was at once 

 recognizable by having the last two thirds of the tail red. It 

 appeared to be the species designated by Schlegel (Mus. des Pays- 

 Bas, Simiae, p. 87) Cercopithecus ascanias, but Mr. Sclater much 

 doubted whether it was legitimately entitled to bear that name. 



Until the synonymy of the West-African Monkeys was more 

 completely worked out, it was not advisable to give it a new name, 

 but it was interesting to have ascertained the correct locality of 

 this Monkey. 



Mr. Sclater exhibited a specimen of the Pheasant from Northern 

 Afghanistan which he had described hi 1885 (P. Z. S. 1885, p. 322, 

 plate xxii.) as Phasianus principalis, and stated that he was pleased 

 to find that his name for this bird antedated that bestowed upon ti 

 by Bogdanow, Phasianus komarovi^, and must therefore be adopted. 

 M. Menzbier had compared typical specimens of P. komarovi with 

 birds from the Murghab and had found them identical. 



The specimen now exhibited had been kindly presented to Mr. 

 Sclater bv Gen. Sir Peter Lumsden, G.C.B., F.Z.S. 



The following extract was read from a letter addressed to the 

 Secretary by Mr. A. Everett, C.M.Z.S., dated Labuan, April 2 1st, 



1887:— 



" You will be interested to know that Mr. John Whitehead has 

 recently returned from the Kina Balu mountains in Northern 

 Borneo, where he made a stay of two months on one of the spurs, 

 at an elevation of 5000 feet. Mr. Whitehead has collected birds 

 chiefly, and there appears to be a considerable proportion of novelties 

 among the skins, although perhaps many of them are only new to 

 the Bornean avifauna. Among those which seem to me to be really 

 new to science are a huge Calyptomena, six times the size of the 

 common Green Manakin, but, hke it, coloured brilliant green and 

 velvety black, only the coloration is differently disposed ; a long- 

 tailed Eurylaemid, which is a very beautiful bird about the size of
