XVIII. — On the Habitat of Uromys aruensis [Gray] and its 

 Allies. By Dr. A. B, Meyer. 



Dr. J. E. Gray, in describing (Ann. & Mag. Nat. Hist. ser. 4, 

 1873, vol. xii. p. 418) a new species of Uromys from my col- 

 lections, introduced it with the following words : — 



" The British Museum received two specimens of a male 

 and female rat, which Dr. A. B. Meyer obtained at Am Island 

 in April 1870, and at Buntimunang, in the south-west part of 

 Celebes, in November." 



This note requires a rectification on my part. I never was 

 on the Aru Islands ; and in April 1870 I was still in England ; 

 in October of the same year I arrived in Java; and it was in 

 November 1871 that I first spent some days collecting in 

 Bantimurang (it should be " Bantimurang," and not " Bunti- 

 munang "). But, besides this, the female Uromys was not 

 procured by me on South-west Celebes ; it belonged to a small 

 collection of animals from the Aru Islands, which I had bought 

 before I came to Makassar, in September 1871. Some con- 

 fusion must have happened in Europe with two of my labels, 

 to have led Dr. Gray to the statement that Uromys aruensis 

 occurs on the Aru Islands and in the south-ioest of Celebes. 

 My diary and collection-notes arc quite positive on this point ; 

 and there can remain no doubt that a mistake has been made. 

 I regret tliat 1 did not see this incorrect statement earlier ; but 

 T now hasten to make known that from my Celebes collections 

 no Uromys reached Europe. Celebes being so very poor in
