THOMAS ON THE [Apr. 16, Sibutu I., Oriolus chinensis and Sarcops calvus, the latter at least is purely Philippine, I cannot help thinking that a more extended knowledge of its avifauna would probably show a preponderance of western rather than eastern species. " In concluding this sketch of the grounds upon which I am induced to consider Palawan and the other islands above mentioned as component parts, from a zoo-geographical point of view, of the Bornean group, I may mention that I hope to be able to obtain a small collection from the mountains of Palawan before long, and also one from Sibutu. 2. O n the M a m m a l s of M o u n t Kina Balu, North Borneo. By O L D F I E L D T H O M A S , Natural History Museum. [Received April 2, 1889.] (Plate XXIV.) The Mammals described in the present paper formed part of the large zoological collections made during 1887 and 1888 on the great mountain Kina Balu in North Borneo by Mr. John Whitehead, a gentleman who, although primarily an ornithologist, yet wisely collected whatever Mammals he was able to obtain in that most interesting and as yet unknown part of the island. The species of which specimens were obtained number 21. Of these 6 were new to science, and 5 more were new to Borneo, thus increasing the known Mammal fauna of the island by uo less than 11. The large number of new species is a most remarkable fact, and one that shows how far we still are from anything like a complete knowledge of the smaller Mammalia and their distribution ; and this is especially the case with the Rodents, to which, as usual in such cases, the majority of the new forms belong. Until more is known of the mammals inhabiting the other mountains of Borneo, it is not possible to draw any general geographical deductions from the present collection ; but it may be noted that, of the additions to the Bornean fauna, one species was previously only known from the Himalayan region, where also is found the nearest ally of one of the new species, two are Sumatran, one is Javan, and one occurs in Celebes. 1. SEMNOPITHECUS HOSEI, Thos. P. Z. S. 1889, p. 159, pi. xvi. a. Skull, 4000 feet. The only other locality known for this species is Baram, on the coast at the junction of Brunei and Sarawak, where the type specinien was obtained by Mr. Charles Hose. The present skull is that mentioned in the original description (supra, p. 159). |
