With I'eference to a note by Mr. Miller {loc. cit. sujira), I 

 believe that his R. affinis is undoubtedly the same as my R. afflnis 

 typica. In my description of this species I noted that the hairs 

 " when nevdy-groion " were annulated ; but this annulation dis- 

 appears extremely quickly, so that it is very seldom that a specimen 

 in annulated pelage is procured. 



With regard to Miller's R. pyrsonota described in the same paper, 

 this is the Malayan form of R. ephipiyiunn from Borneo and is, as 

 Mr. Miller notes, quite distinct from R. affinis. It should really 

 be known as R. ephiiypimn pyrsonota, which saves any possibility 

 of confusion. Mr. Miller has since 1900 described many new 

 species representing island forms or local races of R. affinis or 

 ephijypiion, but, from his strict adherence to binomial nomenclature, 

 which has prevented him from recognising the true specific 

 difference between affinis and ephipjnum, it is impossible to tell to 

 which of these species his new races belong, ancl in consequence 

 to determine the true specific range. I am, however, inclined to 

 believe that they are all races of R. ephippiu7n, and that the true 

 R. affi-nis will be found to have a very restricted range, confined 

 to the Malay Peninsula and possibly Java.

These specimens, which are practically topotypes, are therefore 

 of the typical form. This species, however, appears to be a 

 remarkably stable one, Mr. Miller stating that sjDecimens from 

 Sumatra were indistinguishable from topotyjoes. At the same 

 time S'. tenvAs surdus Mill., from the north of the Peninsula, is 

 distinctly paler and greyer.
