the N.W. Cape of Borneo, some 190 miles into the Indian 

 Ocean, and are divisible into tlu'ee groups — the South 

 Natunas, the Great Natunas, and North Natuna or Pulo 

 Laut. The collection now described by Mr. Hartert was 

 formed by Mr. A. Everett on Sirhassen Island in the southern 

 group, in September 1893, and on Bunguran Island, the 

 largest of the Great Natunas, in September and October 

 1893, The specimens are referred to 66 species, of which 

 Malacopteron cinereum bungurense, Stachyris natunensis, 

 Mixornis everetti, Graitcalus bungurensis, and Philentoma 

 dubium are described as new. 



Mr. Hartert concludes that, judging from the present 

 material, the Natunan Ornis is more Malaccan than Bornean, 

 at least live of the species being identical with those of the 

 Malay Peninsula, while representative forms of them are 

 found in Borneo. Moreover, some of the new species are 

 more nearly allied to Malaccan than to Bornean forms.
