SCIURUS MACCLELLANDI KONGENSIS, subsp. n. Sciurus m. barbei Blyth, Bonhote, P. Z. S. 1900, p. 194. This collection contains three more specimens of this Squirrel, which, on a close comparison with specimens from other localities, is seen to form a distinct Siamese race of Sc. macclellandi. The form it most nearly approaches is Sc. m. barbei, from which it may be distinguished by the general coloration being much greyer and the outer light stripes of a much paler yellow ; these characteristics will hold good at all seasons of the year, for from the material at hand it appears that this race has a seasonal change, which is not known among the Burmese specimens. Description of type. (Winter pelage.) General colour greyish, each hair being dark at its base with a very pale tip. The outer light stripes very broad and well-marked and of a very pale cream. The inner light stripes slightly darker in colour, but narrow and short. All the three dark stripes dull, owing to each hair having a rufous tip. Hairs of the ears long and conspicuously white, those near the tip having no black bases. Underparts pale ferruginous. Dimensions:- Head and body 122 mm. ; tail 133 : hind foot 29 ; ear 14. |
