18 LIASIS PETERSII. 



ti7ius, the black markings along the back do. They re- 

 semble much more the pattern as it is found in Python 

 retiadatus and bivittatus ; a network of patches of darker 

 scales distributed among others of a lighter colour. The 

 rings encircling the hinder part of the body and tail in 

 L. amethystinus of which I never missed the traces either 

 in old or in young examples are wanting in Liasis Petersii. 

 Our specimen was collected by Dr. Semmeiink at Laran- 

 toeka on the E. coast of Flores ; the Berlin one came from 

 Kupang, Timor. Explorations of the neighbouring islands 

 must decide how far its geographical range extends.
