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.
SUS NATUNENSIS sp. nov.
1894. _Sus_ sp. THOMAS and HARTERT, Novitates Zoologicæ, I, p.
660. September, 1894 (Bunguran).
1895. _Sus_ sp. THOMAS and HARTERT, Novitates Zoologicæ, II, p.

_Type._--Adult female (skin and skull) No. 104856 U. S. National
Museum. Collected on Pulo Laut, North Natuna Islands, August 6, 1900.
Original number 609.
_Characters._--Externally much like the Tenasserim form of _Sus
cristatus_, but smaller; body brownish in marked contrast with black
legs and face; skull conspicuously shorter and broader.
_Fur._--The fur throughout consists of bristles with no admixture
of softer hairs. The bristles are everywhere less stiff than in the
Tenasserim pig, but the difference is most noticeable in the mane,
which, though well developed (about 80 mm. in length), is composed of
bristles very slightly coarser than those of the surrounding parts,
and of not more than half the diameter of the corresponding hairs in
females of _S. cristatus_. Muzzle, chest, belly and ears nearly bare.
_Color._--General color black, clear and unmixed with brown on legs,
throat, and face, but elsewhere heavily overlaid with brownish buff,
particularly on back and sides. The brownish wash ceases abruptly
just in front of ears, leaving the face and cheeks clear black. A
conspicuous dull buff streak 100 mm. long and about half as wide at
middle extends back from angle of mouth to level of posterior canthus
of eye. It is sharply outlined above by black of cheeks, and below by
that of chin. A faint buffy mark beneath eye. Tail like back.
