Ova,—One killed 3rd June, contained nine eggs with no trace of embryo, 
Colour,— One small one 123” long, was so different to the adult in colour, as 
to mislead us at first sicht. It was blackish, with thin white transverse bands, 
in the anterior two-thirds of the body ; (25 im all), and a white collar. Under 
parts dirty white. Upper labials, antoculars, and postoculars dull white.

hatched from a cluster of eggs already recorded by us in the Society's 
Journal, page 189 (No. 1) of this Volume (XIII), obtained in Rangoon, and 
Districts, L. B.*

Ventrals.—153. 
Subcaudals.—41, 
Supraoculars.—4 to 6 scales intervene in front, 8 to 10 behind. 
Nostril— We do not concur with the remark that the nostril is situated 
between three shields, The invariable arrangement is as follows :—It is 
contained in a single, large, irregularly-formed scale. The anterior two-fifths 
is extranaral, and forms a bold vertical pillar, bifid above, where the anterior 
part of a crescentic scale dips down, The anterior limb of this pillar ends 
abruptly behind the upper part of the rostral, the posterior limb passes 
obliquely backwards and upwards to become lost in the roof of the nostril, 
and is bounded below for a short distance by a fissure, which is itself 
lost in the roof, At the base of the pillar, a limb passes backwards and up- 
wards to become lost at the back of the nostril, and is skirted above by a 
fissure which also becomes lost inthe scale. The nostril is placed behind the 
pillar,and between the two oblique limbs just referred to, It is large and 
roughly funnel-shaped,
