Seems to be rather uncommon, as this spécimen is the only one, collected by the 

 différent expéditions, though the species occurs ail over New Guinea. It is uniformly brown 

 on the back; the dark brown latéral band is very distinct, also a greyish bar below the eye; 

 throat greyish. The flanks below the dark band and the sides of the thick tail are spotted 

 with greyish-brown, the spots on the tail forming oblique vertical bars. 



L. mïdleri is with L. albofasciolatum (Gthr.), a form found in German New Guinea the 

 largest Lygosoma of the Archipelago, and also found in Ceram, Aru and Kei Islands.
