30. Dendrophis Meekt, sp. n. 
Maxillary teeth 32 or 33. Eye very large, as long as its 
distance from the centre or the anterior border of the nostril. 
Rostral nearly twice as long as deep, just visible from above ; 
internasals as long as the prefrontals; frontal once and one 
third to once and a half as long as broad, as long as its 
distance from the end of the snout, much shorter than the 
parietals ; loreal once and two thirds or twice as long as deep ; 
one pre- and two postoculars ; temporals 2+2 or 3; eight or 
nine upper labials, fourth and fifth or fourth, fifth, and sixth 
entering the eye; five lower labials in contact with the ante- 
rior chin-shields, which are shorter than the posterior. Scales 
in 13 rows, vertebrals about as large as outer. Ventrals 
170-178; anal divided; subcaudals 139-147. Dark olive 
above; upper lip white, sharply limited above by a black 
line passing through the eye; lower parts pale olive, more 
or less freckled with darker. 
Total length 1160 millim. ; tail 420. 
Several specimens. 
This species is very closely allied to D. lineolatus, from 
which it may be distinguished by the longer parietal shields 
and the black demarcation line running along the upper 
border of the labials. I am not able to identify it with any 
of the doubtful species described by Macleay and Donglas 
Ogilby.
