Family Dryiophid^e. 
Dryiophis Oatesii, sp. n. (Plate D.) 
Allied to DryiopJiis Kit-tlandii, but the rostral shield is not reverted 
to the upper surface of the head ; the proeocular reaches, to the upper 
surface only, remaining far distant from the vertical. Two post- 
oculars : temporals 1+2 + 2, the anterior being the smallest, and in 
contact with the upper post-ocular. 
Head with very peculiar colouration ; the upper surface is orna- 
mented by a pink T-shaped figure, the horizontal bar stretching from 
eye to eye, and the vertical part occupying the middle of the occipital 
shields. This figure is finely mottled with black. An irregular, 
oblique, blackish line from the eye to the penultimate upper labial, 
the pink temporal scales margined with black. Body coloured as in 
D. Kirtlandii. 
Total length 47 inches ; the tail measuring 19 inches ; length of 
the cleft of the mouth 14 lines.
