254 CALAMARIA PRAKKEI. 
presenting itself on those scales, this coloration extends 
itself over a length of 20 à 30 scales growing less and 
less clear in proportion as the scales advance to the 
tail. It is remarkable that in specimen f many scales 
on the upper part of the body have an accumulation of 
dark pigment in their centre, this giving rise to an indi- 
cation of dark longitudinal stripes and so forming an ap- 
proach to the coloration of C. Gervaisi, In the other spe- 
cimens also, in some parts of the body the presence of a 
dark centre in some of the scales is more or less promi- 
nent. The four anterior upper labials yellowish white, the 
fifth on its fore and under part yellowish white, behind 
and above dark brown, the margins between the upper 
labials are indicated by brown lines. The lower labials 
yellow, also separated from another by a dark line. Chin- 
shields yellow, the anterior pair with a dark spot on the 
anterior part. This coloration of upper and lower labials 
and chin-shields is in specimen a only slightly indicated. 
In some specimens especially in specimen f may be found 
an indication of a light collar. Ventrals yellow without dark 
lines between them, and with a little dark spot on each 
side in the outer angle (in the specimens e and f on some 
‘of the ventrals small dark spots). A dark line running 
along the middle of the tail, subcaudals yellowish, the 
hindmost with dark lines on the margins between them, 
which lines together with the dark line along the middle, 
give rise to a feather-shaped coloration at the end of the 
tail. In specimen a, which, on account of its inferior size 
and other points of difference, I take to be a young one, 
neither the dark line along the middle of the tail nor 
the dark margins between the hindmost subcaudals are to 
be seen.
