1872.] ON BIRDS FROM THE PELEW AND MACKENZIE ISLANDS. 87 



4. On a fourth Collection of Birds from the Pelew and 

 Mackenzie Islands. By Dr. Gr. Hartlaub, F.M.Z.S., 

 and Dr. O. Finsch, C.M.Z.S. 



[Received December 6, 1871.] 



It was in the year 1867 that we had the first opportunity of re- 

 porting to this Society* on a small collection of birds from the Pelew 

 and Mackenzie Islands, which, from their geographical position, may 

 be considered of especial interest. These groups of islands are 

 close to each other, connected by several small islets, and form the 

 most western corner of the extensive archipelago of the Carolines. 

 Since that date we have received two other collections from the 

 Pelewsf, forwarded to us through the Museum Godeffroyanuin of 

 Hamburg and the Museum of Altona (Dr. Semper), which have 

 extended our knowledge of the avifauna of this group to a high 

 degree. It is with great satisfaction that we now record the receipt 

 of a new and still more complete collection from the localities men- 

 tioned above, sent to us for scientific determination by Mr. Johann 

 Cesar Godeffroy, to whom science is greatly indebted for the explo- 

 ration of some almost unknown groups of islands in the Pacific. 



This collection was formed by Mr. Kubary (a young traveller in 

 the service of Mr. Godeffroy, whom we had the pleasure of men- 

 tioning in terms of commendation in our last article on birds of Savai, 

 P. Z. S. 1871, p. 22) on the island of Uap, of the Mackenzie group, 

 and by Capts. Heinsohn and Peters, masters of vessels belonging to 

 Mr. Godeffroy, partly at the same island, but chiefly on the Pelews. 

 Thanks to the zeal and diligence of these gentlemen, we are now in 

 the pleasing situation of being able to give a far more complete ac- 

 count of the ornithology of these interesting islands. Not only do 

 we become better acquainted with some little-known species, but the 

 total number of species has been increased. Amongst these additions 

 no less than nine we have the pleasure of introducing as new ; and 

 what is more important, some of them appertain to genera not yet 

 known from this locality — such as Noctna, Caprimulgus, Campe- 

 phaga, and Phlegcenas. 



Our last list of Pelew birds embraced forty-one species, now we 

 have to add eleven, making the total number fifty-two. Of the 

 Mackenzie group or Ulathi, only the island of Uap has been explored. 

 Here we were previously acquainted with six species only (Myzo- 

 mela rubratra, Monarches godeffroyi, Calornis kittlitzi, Ardea 

 sacra, Numenius phceopus, and Tachypetes minor) ; now we are able 

 to enumerate twenty. The total number of known birds of this 

 western portion of the Carolines is sixty- four ; but of this number
