The following pages contain a list of the birds collected by Mr. KOCH and by 

 Mr. LORENTZ in the southwestern and in the southern part of New Guinea. 



Dr. J. W. R. KOCH brought together in 1904 small collections of birds at the Etna 

 Bay and at Merauke. Dr. H. A. LORENTZ, who was exploring New Guinea along the Noord 

 River in 1907, made during this expédition a fine collection of about 480 skins and collected 

 aftenvards also some birds at Merauke. The stations along the Noord River can be seen on 

 the sketch-map on the next page. The birds labelled Noord River only hâve been collected 

 chiefly near Bivak Island, where the steamer „Zwaluw" was stationed, or between Bivak 

 Island and Van Weel's kamp. The Varen River, along which only two birds hâve been 

 collected, is a right tributary of the Noord River, near the mouth. The highest points 

 reached are the summit of the Resi Mountains (about 900 m.) and of the Hellwig Mountains 

 (more than 2000 m.). Among the birds from the Noord River-region some new forms occur, 

 while several others are already known from the Fly River. The collections frorrï Merauke 

 contain some Australian forms, which till yet hâve not been recorded from New Guinea ; the 

 fauna in this part is decisively Australian. I hâve the pleasure to offer hère my best thanks 

 to Dr. E. Hartert, who was so kind to compare some examples with type-specimens in 

 the Tring Muséum and who has given me important informations about them; also I hâve 

 to thank Dr. R. Gestro of the Muséum at Genoa for kind assistance.
