Colour (Spirits) : — Uniform brownish above, lighter on the 
head and the sides. Head with dirty smudges and a few scattered, 
irregularly placed dark brown spots. Sides and back with irregu- 
larly distributed, more or less abundant dark brown spots, which in 
many cases exactly cover one scale. Under surfaces uniform 
yellowish olive, or finely peppered with grey. Throat yellowish or 
dark bluish grey. 
Total length oflargest specimen, 1525 mm., tail, 250 mm. 
I have examined four specimens of this Demansia and think it 
will prove constantly distinct from D. nuchalis. After examining 
Dr. Gunther’s type specimen Dr. Boulenger placed this species in 
the synonomy of D. nuchalis, possibly regarding such slight differ- 
ences founded on a single specimen as not of specific value. With 
four additional specimens at hand however, all of which differ in 
the same characters from D. nuchalis, I propose to raise D. affinis 
to specific rank. When placed side by side the two forms appear

strikingly different, but a closer examination shows that the differ- 
ences are mainly in the general appearance, the outline of the head 
(see I ext figs. 6a and 6b), and the colouration. Also, Messrs. Lucas 
and Frost record a specimen in which the scales are in twenty-one 
rows, the greatest number recorded for the genus.
