With reference to a note by Mr. Miller (loc. cit. sujyra), believe that his R. affinis is undoubtedly the same as my R. affinis typica. In m y description of this species I noted that the hairs " when newly-grown" were annulated; but this ambulation disappears 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. ephippium from Borneo and is, as Mr. Miller notes, quite distinct from R. affinis. It should really be known as R. ephippium 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 ephippium, but, from his strict adherence to binomial nomenclature, which has prevented him from recognising the true specific difference between affinis and ep>hippium, it is impossible to tell which of these species his new races belong, and in consequence to determine the true specific range. I am, however, inclined to believe that they are all races of R. ephippium, and that the true R. affinis will be found to have a very restricted range, confined to the Malay Peninsula and possibly Java.

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. SCIURUS VITTATUS Raffles. Sciurus vittatus Raffles, Trans. Linn.
