Java: Buitonzorg, 1 spec. 
Upper-labials five, the first pair of lower-labials are not in contact 
with each other; thero is no azygos shield in contact with the ante- 
rior chin-shields. Head rather long , snout somewhat pointed ; vertical 
nearly twice as long as broad, six-sided, with a very acute posterior 
angle. The third and fourth upper-labials entering the orbit. One pos- 
terior and one anterior ocular shield. On both sides of the small scale 
lying in the middle between the occipitals, lies a large white-coloured 
scale nearly twice as broad as the surrounding ones. Our specimen 
has 192 ventrals and 21 pairs of subcaudals. 
Upper parts black except the two large scales already mentioned, 
lying just behind the occipitals. Underparts and the outer row of 
scales spotlessly whitish. It may be mentioned as a curious fact 
that our specimen in getting dry after being taken out of spirits as- 
sumes an altogether different coloration. Nearly all the scales of the 
back assume a greyish-blue colour, whilst the scales of the outer 
series, the ventrals and the subcaudals get the glossy whitish-yellow 
colour peculiar to china. I think this change of colour must be attributed 
to the air getting between the epidermis and the colour-layer of the scales. 
Our only specimen is a rather small one measuring only 24 c, m.

This specimen differs from Dumeril's description and from the only 
specimen in the Leyden Museum from Celebes by the absence of a 
posterior ocular and in not having one or two small scales between 
the chin-shields. There is no light spot on the head , the collar round 
the upper part of the neck is very clearly visible, and every scale 
ha^ a hght spot in its centre. As there is only one specimen in the 
collection, I am not in a position to make out whether these pecu- 
liarities are characteristic to all specimens from Sumatra, in which 
case these ought to be regarded als belonging to a local variety of 
the species.
