MAMMALS COLLECTED IN SIAM. 357 
siamensis Gyldenstolpe,! based on a single semi-adult specimen from 
Koh Lak. It is stated to be most nearly related to 7’. minor malac- 
canu. Anderson, while the skull resembles that of 7. javanica Horsf., 
but is narrower. The former is unknown north of the Malay 
States, and javanica has never yet been correctly recorded from 
continental Asia ; and though it is possible, as in the case with 
several other species, that it occurs in Java and again in Indo-China 
but is absent from the greater part of the Malay Peninsula (c.f. 
Bandicota, Helictis, ete.), yet, since a good deal of thorough collecting 
has been done in the area now being dealt with, it is curious 
that no animal of the kind indicated has been obtained previ- 
ously —if it exists, Tupaias are quite conspicuous and not at all 
shy. 
Gyldenstolpe also obtained at the same place examples which 
he calls belungeri (tom. cit., p. 18) and it is probable that in separa- 
ting simmensis he was misled by the immature characters of the skull 
in his type specimen.

13. Tupaia glis cambodiana subsp. nov. 
Tupitia concolor, Kloss, P. Z. 8. 1916, p. 37. 
This is the animal previously referred by me, for geograph- 
ical reasons, to 7’. concolor Bonhote, though I noted atthe time 
that it was not typical; further examination leads me to regard it 
as distinct. Though it closely agrees with 7’. concclor in size, the 
mammary formula for that form is believed to be 2—2=4, in this 
it is 3 — 3=6 
1. concolor further (vide Bonhote, P. ZS. 1907, p. 7) is 
uniform grizzled greyish-green above and the neck-stripe is so 
faint that unless special search is made it is liable to be overlooked ; 
Lyon also (Proc. U.S. Nat. Mus. 45. p. 68) does not mention any - 
neck-stripe at all and states that the upper parts are grizzled ochra- 
_ ceous-buff and blazkish, anteriorly more buffy, posteriorly more 
ochraceous, but not conspicuously so, while the tail is similar to
