MAMMALS OF THE NATUNA ISLANDS 121 



MUS SABANUS Thomas. 



1887. Mus sabanus Thomas, Ann. and Mag. Nat .Hist., 5th sen, xx, p. 



270. October, 1887 (Mt. Kina Balu, Borneo). 

 1894. Mils sabanus Thomas and Hartert, Novitates Zoologicae, i, p. 658. 



September, 1894 (Bunguran). 



Thirteen skins and one extra skull, all from Bunguran. There is 



little probability that this rat is the same as the true il/?c5 sabanus of 



Borneo. 



MUS RAJAH Thomas. 



1894. Mus hellwaldi Thomas and Hartert, Novitates Zoologicae, i, p. 658. 

 September, 1894 (Bunguran). 



1894. Mus rajah Thomas, Ann. and Mag. Nat. Hist., 6th ser., xiv, p. 451. 

 December, 1894 (Mount Batu Song, Borneo). 



1895. Mus rajah Thomas, Novitates Zoologicae, 11, p. 26. February, 1895 

 (Revised determination of Bunguran specimens). 



Six specimens (one in alcohol) from Bunguran, two from Pulo Lin- 

 gung, one from Pulo Laut, four (one in alcohol) from Sirhassen, and 

 one (in alcohol) from Pulo Midei. It is doubtful whether these series 

 are referable to one species or whether any of them are the true Bor- 

 nean Mus rajah. The material is not wholly satisfactory, and I have 

 been unable to examine specimens from Borneo. 



MUS NEGLECTUS Jentink. 



1894. Mus rattus var. Thomas and Hartert, Novitates Zoologicae, i, p. 

 658. September, 1894 (Bunguran). 



1895. Mus 7ieglechis Thomas and Hartert, Novitates Zoologicae, 11, p. 

 492. December, 1895 (Bunguran). 



Five specimens from Pulo Lingung, one from Pulo Midei, and nin^ 



from Sirhassen. In the absence of Bornean material, I follow Thomas 



and Hartert in referring the Natuna rats of the ' alexandrt?ms ' type to 



]\Ius neglectus. 



SCIUROPTERUS EVERETTI Thomas. 



1894. Sciicropterus phayrei Thomas and Hartert, Novitates Zoologicae, 



I, p. 660. September, 1894 (Bunguran). 



1895. Sciuropterus evereiti Thomas, Novitates Zoologicae, 11, p. 27. Feb- 

 ruary, 1895 (Revised determination of Bunguran specimens). 



1895. Sciuropterus everctti Thomas and Hartert, Novitates Zoologicae, 



II, p. 490. December, 1895 (Bunguran). 



Two specimens, both from Bunguran ; an immature male taken 

 July 4, and an adult female taken July 21, 1900. 



PETAURISTA NITIDULA Thomas. 



1894.. Pteroinys nitidus Thomas and Hartert, Novitates Zoologicae, i, p. 

 660. September, 1894 (Bunguran).
