1895. Tragulus javanicus Thomas and Hartert, Novitates Zoologicæ, II, p. 492. December, 1895 (part, specimen from Pulo Laut).
Type.—Adult female (skin and skull) No. 104616 U. S. National Museum. Collected on Pulo Laut, North Natuna Islands, August 11, 1900. Original number 625.
Characters.—Smaller than Tragulus javanicus from Borneo or Bunguran and very pale in color. Black clouding of upper parts inconspicuous, but dark nape band well defined.
Color.—Back and sides light ochraceous-buff everywhere clouded by the blackish hair-tips, but these never in excess, except perhaps along middle of back and across lumbar region. Flanks, shoulders, neck, outer surface of legs and narrow line dividing color of sides from that of belly pale ochraceous. Nape band clear black, sharply defined from color of sides but quickly fading into that of shoulders. Top of head dull dark brown. A faint pale stripe over and in front of eye. Throat markings normal, the dark bands like neck. Collar very narrow. Under parts and inner surface of legs white. A faint yellowish shade along middle of belly. Tail white beneath and at the tip, ochraceous faintly shaded with brown above.
Skull.—The skull of the type, though fully adult and with all the teeth distinctly worn, is smaller than in Bunguran specimens so young that the posterior molars are still below the rim of the alveoli. In form, however, it shows no marked peculiarities, though in general it appears to be somewhat broader in proportion to its length than that of the Bunguran animal.
Teeth.—Teeth as in specimens of Tragulus javanicus from Bunguran except that the premolars, both above and below, are shorter and broader, a difference which may prove to be an individual peculiarity only.
Measurements.—External measurements of type: Total length 539; head and body 444; tail vertebræ 95; hind foot 107; hind foot without hoofs 95.
Cranial measurements of type: Greatest length 90 (94[9]); basal length 83 (87); basilar length 78 (82); occipito-nasal length 83 (89); length of nasals 25 (29.6); diastema 9.2 (9.8); zygomatic breadth 41.4 (40); least interorbital breadth 26.4 (25); breadth of braincase over roots of zygomata 29.4 (28.4); mandible 72 (75); maxillary toothrow (alveoli) 31.6 (34); first upper premolar 6.4 × 2.8 (7 × 2.6); mandibular toothrow (alveoli) 35.8 (38).
Specimens examined.—One, the type.
Remarks.—This is a pallid form of Tragulus javanicus, a species which apparently shows very little tendency to become differentiated into local races. The characters of the Pulo Laut animal were pointed out by Thomas and Hartert in 1895.
