The last specimen, the largest (620 mm., tail 120), differs from typical examples 

 in the absence of the black streaks on the head, which is uniform brownish above and 

 whitish beneath, with black lines on the sutures between the upper labial shields ; 

 back with black spots or cross-bars, some of which are oblique; sides of belly and 

 lower surface of tail dotted with black. Represents the T. novce-gtdnece v. Lidth de 

 .Jeude (Nova Guinea, ix., Zool. p. 271, 1911), which should probably rank as a variety 

 of T. picturatus.
