With reference to a note by Mr. Miller (loc. cit. sitj^ra), 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 newly-groimi " 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. 7:>y>'st>?ioia.d escribed in the same paper, 

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

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

 be known as R. epli%i:>pmm pyrsonota, which saves any possibility 

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

 species rej)resenting island forms or local races of R. affinis or 

 ephip>pium., but, from his strict adherence to binomial nomenclature, 

 which has prevented him from recognising the true specific 

 difference between affinis and ep)liiijpium, it is impossible to tell to 

 which of these species his new i-aces belong, and in consequence 

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

 believe that they are all races of R. eptliippiu'm, and that the true 

 R. affinis 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 specimens from 

 Sumatra were indistinguishable from topotypes. At the same 

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

 distinctly paler and greyer.
