ON SOME MAMMALS COLLECTED BY Dr. E. MODIGLIANI 



IN SIPORA, MENTAWEI ISLANDS 



BY OLDFIELD THOMAS 



Among the islands whose Mammalogy has been hitherto 

 totally unknown, the Mentawei Islands, west of Sumatra, have 

 occupied a somewhat conspicuous place, especially since Engano 

 and Pulo Nias, thanks to the collections of Dr. Modigliani, and 

 the Natuna Islands, to those of Mr. Everett, have been removed 

 from that category. Dr. Modigliani having now followed up his 

 previous explorations by an investigation into the Fauna of Si- 

 pora (^) , the second largest island of the Mentawei group , I 

 have felt great pleasure in being privileged to work out the 

 Mammals he collected there. 



The specimens have all been presented by Dr. Modigliani to 

 the Museo Civico, Genoa, to whose authorities, the Marquis 

 G. Doria and Dr. R. Gestro, I owe thanks both personally 

 for the pleasure I have had in working them out, and also 

 for the generosity with which they have ceded to the British 

 Museum a duplicate set of specimens, including a co-type of 

 each of the species here described as new\ 



The Mammals as a whole prove to be of remarkable and 

 quite unexpected interest, as judged by the amount of peculia- 



(') Tliis islaiid has been variously called Sipora, Sikobon, or Sereinu. Tlie first of 

 Uiese names is that g-enerally used in German and English maps, the second I tlnd 

 as an alternative to the first in Stemfoort and Siethoff's excellent Dutch Atlas of 

 the East Indian Archipelago, while tlie third occurs, also as an alternative to the 

 first, on Dr. Modigiiani's labels.
