from the edge to about the middle of the wing, where it is lost in an 
indistinct bifurcation : the most posterior extends from the angle of the 
wing, along its posterior border, right up to the groin, first bifurcating: 
while the middle one, which also ends in a bifurcation, is in extent, 
intermediate between the other two. 
Median gular fold light lemon-yellow; lateral gular folds dull 
scarlet beneath. 
The dull red bands on the wing membranes, and on the under-surface 
of the gular side-folds are described as scarlet in life.

In accord with Mr. Boulenger’s Synopsis of the Genus j Draco (Cata¬ 
logue of the Lizards in the British Museum, second edition, 1885, 
pp. 253-255), this fine species would be placed with D. quinquefasciatus 
in the second section of the genus as follows:— 
Section 1. Nostril lateral, directed outwards : 17 species. 
Section 2. Nostril pierced vertically, directed upwards:— 
A. Tympanum naked (_D. hsematopogon , 1). mela- 
nopogon, D. blanfordii , D. dussumieri , D. tseni - 
opterus , D. obscurus). 
B. Tympanum scaly ( D . quinquefasciatus , D. nor - 
villii). 
Its place among the Indian species of the genus is shown in the 
following table, modified from Mr. Boulenger’s Synopsis in the Fauna of 
British India , Beptilia and Amphibia, p. 112 :— 
A. Nostrils lateral : tympanum scaly. D. maculatus. 
B. Nostrils vertical:— 
1. Tympanum naked. J). blanfordii , 
D. dussumieri , D. tseniopterus. 
2. Tympanum scaly and hidden . _D. norvillii. 
A single specimen was taken by Dr. F. H. Norvill of Doom Dooma, 
Upper Assam, to whom I have much pleasure in dedicating the species.
