T. (Iter, Macleay, only differs from T. pictnratus in having a 

 longer and narrower frontal shield, which in the two examples is 

 from one and three-fourths to one and nine-tenths times as long 



as wide, and is much longer than the parietals. 

 cannot be separated from T. picttiratus.

2. Dendrelaphis schlexckeri, sp.nov. 



Maxillary teeth 20. Eye very large, as long as its distance 

 from the middle of the nostril. Rostral about twice as broad as 

 deep, just visible from above; internasals as long as the pre- 

 frontals; frontal once and a half to once and three-fifths as long 

 as broad, much longer than its distance from the end of the snout, 

 shorter than the parietals ; loreal elongate, between twice and 

 thrice as long as broad; one pre- and two post- 

 oculars, the lower small; temporals 2 -f 2 or 1-1-2; 

 eight upper labials, fourth and fifth entering the 

 eye; four lower labials in contact with the 

 anterior chin-shields, which are much shorter 

 than the posterior, the fifth greatly enlarged. 

 Scales in 13 rows. Ventrals 185 to 187; anal 

 divided; subcaudals 118 to 132. Upper surface 

 olive-brown, the neck and anterior portion of 

 the body much darker, with the vertebral series 

 of scales bluish- white, tipped with pale brown, 

 forming a conspicuous band ; a narrow black 

 streak from the snout to the neck; upper labial, 

 lower surface of head, and throat yellow; lower ( >^ H) 



surface of body bluish-white, indistinctly spotted with darker. 

 (Named for its discoverer, the Rev. H. P. Schlencker of the 

 London Missionary Society.) 



This species is closely allied to Dendrelaphis papuensis, but 

 difiers constantly in the larger eye, longer frontal, and decreased 

 number of lower labials in contact with the anterior chin-shield. 

 Five specimens are in the collection, the largest measuring 1,100 

 millimeters, the tail being 350.
