Specimens examined.—Hight from the type-locality, two 
taken in March and six in May. 
Remarks.—This is a depauperated form of S.f. griseimanus 
(M.-Edw.), inhabiting the sterile coastal plain of Phanrang. 
Its range inland is limited by the forested hills, 10-20 miles 
to the west, where S. f. griseimanus occurs.

9. Tamiops macclellandi laotum, subsp. n. 
Outer pale stripes interrupted on the shoulders, only the 
median stripe black, under parts cream-colour. 
Above a fine grizzle of black and buffy, the general colour 
effect being brownish grey. A median dark stripe com- 
mencing behind the shoulders, bordered by ,greyish-buffy 
stripes more buffy than the head, these in turn bordered 
externally by ferruginous stripes speckled with black deeper 
than the head; below these come buff stripes, followed below 
by stripes the same colour as above. A buff stripe from 
the muzzle along the sides of the neck. Hind feet buffy, 
more so than the fore feet. Hairs of ears with white tips 
and black bases. 
Below creamy, the hairs with grey bases. Tail annulated 
black and ochraceous, the hair tipped with pale buff. 
The series varies: the most north-easterly examples are 
darkest and have the dark dorsal stripes most intense—

southernmost specimens are palish and most buffy, one 
especially (No. 7238/S from Ban Houei Huo Chang) 
practically lacking any rufous suffusion above.
