MAMMALS COLLECTED BY DR. W. L. ABBOTT IN THE REGION OF 

 THE INDRAGIRI RIVER, SUMATRA. 



BY GERRIT S. JMILLEK, JR. 



During Augu.st and September, 1901, Dr. AV. L. Abbott vis- 

 ited the Indragiri river, eastern Sumatra, and the two large islands 

 opposite its mouth, Linga and Sinkep. The valuable collections 

 which he secured were all presented to the United States National 

 Museum. This paper contains an account of the mammals, and is 

 published here by permission of the Secretary of the Smithsonian 

 Institution. 



Linga Island was visited by Dr. Abbott and Mr. C. Boden Klott 

 in July, 1899. At this time nine species of mammals were ob- 

 tained:^ Tragulus " napu'' (= T. pretiosus), Sciurus tenuis, S. 

 notatus, Mus lingensis, Tupaia tana, T. malaccana, Pteropus 

 vampyrus, Macacm " cynomolgus," and Semiiopithecus matirus. 

 In 1901 the list was nearly doubled by the addition of Tragulm 

 javanicus, Sus vittatus, Ratufa notabilis, Rhinosciwus laticaudatus, 

 Mus fremens, Mus finnus, Viverra tanghmga and Arctogalidia 

 simplex. The presence of all of these, except the Rhinoscmrus and 

 the two rats, was, however, suspected during the earlier visit. 



Hitherto the mammal fauna of Sinkep Island has been quite 

 unknown ; and I cannot find that any of the accounts of the 

 manmials of Sumatra refer specifically to the region of the Indragiri 

 river. 



Manis javanica Desmarest. 



An adult female was dug from a burrow in a hillside on Sinkep 

 Island, September 1, 1901. Total length, 440; head and body, 

 220; tail, 220. Weight, 4.7 kg. The uterus contained a f wtus 

 92 mm. in length. In this specimen the tail measures only 25 mm. 

 The outlines of the scale are clearly marked on head, body and 

 tail, but very indistinctly on the legs.
