ON MAMMALS COLLECTED BY Mr. H. C. ROBINSON 

 ON TIOMAN AND AOR ISLANDS, S. CHINA SEA. 



By OLDFIELD THOMAS, f.r.s. 



T HAVE been entrusted l)y Mr. H. C. Robinson, of the Kuala 

 Lumpur Museum, with a number of mammals collected by him 

 during 1906 on certain of the smaller islands round the Malay 

 Peninsula. The majority were obtained on the islands of Tioman and 

 Aor, off the east coast of Johore ; and in the present paper I confine 

 myself to these, as those from other localities are of little special 

 importance. 



The mammals of Tioman and Aor have hitherto only been known 

 from papers by Mr. G. S. Miller on the material collected by Dr. W. L. 

 Abbott, and now in the U.S. National Museum. In his first paper on 

 the subject * Mr. Miller gave a list of the species obtained on Tioman 

 in 1899, while the Aor ones and some additional Tioman species are 

 included in a later paper.f 



Mr. Miller's Tioman list is as follows : 



Sciurus tenuirostris 



Macaca " cynomolgus " { = 



fascicularis) 

 Tupaia sordida 



Parad oxurus hermaphrodi- 

 tus 



„ tenuis 

 Mus stridens 

 „ tiomanicus 

 oliscin"us 



Ratufa tiomanensis + | Tragulus rufulus 



§ Mr. Robinson obtained all of these, with the exception of Sciurns 

 tenuis, Mus stridens and M. ohscnrus, and, in addition, the following: 



Pteropus hypomelanus lepi- Rhinosciurus robinsoni, .<s^j. v. 



dus Mus surifer 



Galeopterus taylori, sp. n. Athemrus tionis, sp. n. 

 Petaurista melanotus |

§ Tioman was again visited in Sept., 1907, when Mus stridens, Sciurus tenuis, 

 and a form of Schirus hilimitatus which may possibly prove distinct were obtained. 

 Several bats vrere also collected, amongst them being Cheiromeles torquatus and 

 an EmbaUonura very close to E. peninsuJaris which is widely distributed 

 throughout the Peninsula and adjacent islands. The only species from the 

 island which has not been secured is Mus pullus, Miller, a synonym of Mus 

 obscurus, Miller, which is preoccupied in the genus. Dr. Abbott obtained a single 

 specimen of it. The "species" is very doubtfully distinct from the form of 

 M, concolor, Blyth, inhabiting the mainland. — H.C.R,
