Note. P. bivittatus Schleg. has been regarded by BoULENGER 

 as a synonym of P. molurus L. Werner (op. cit.) distinguishes 

 P. bivittatus as a distinct species, after having seen in the 

 Vivarium in Vienna two kinds: light Pythons {molurus) and 

 dark Pythons {bivittatus). The difference between these two 

 forms is in the colour, in the scaling of the head and in length. 

 Werner describes them as follows : In P. molurus there is one 

 labial entering the eye; the animal does not grow longer than 

 about 4 M. and is of a greyish- or yellowish-brown colour, 

 with reddish-brown, dark-edged spots, those of the flanks
