36 SPOLIA ZEYLANIOA. 
snake, and which should be called Dendrelophis tristis, not Dendro- 
phis pictus. I have little doubt now that the British Museum 
artist painted this from a Ceylon specimen. This variety, which 
may be called taprobanensis, agrees with the Indian form in the 
following ways: (1) the narrew vertebral row of scales, which, 
though enlarged, are considerably longer than broad ; (2) having 
only two supralabials, the fifth and sixth normally touching the 
eye ; (3) narrow black posterior borders to the second, third, 
and fourth supralabials (and first, too, sometimes) ; (4) a narrow, 
short, and rather obscure postocular black stripe. 
[have prepared and examined the skull of one of these specimens, 
and find the nasal bones, the ridges on the parietal bones for mus- 
cular attachment, and the maxillary dentition—in that the posterior 
teeth are shorter than the anterior—all agree with the Indian form, 
figures of which appear in the diagram accompanying my article in 
the Bombay Journal (A, a to g). The only difference isin the 
number of the maxillary and pterygoid teeth, which exceed those 
in the usual Indian form. 
The dentition of this is herewith given with that of all my Indian 
skulls for comparison :—

It will be seen that the dentition agrees with that of a specimen 
from the Nilgiri Hills, collected many years ago, in which I omitted 
to note the distinctions in colour and markings given above, so that 
it is possible that the Ceylon form may, as in many other cases, be 
found also in the South Indian Hills.
