SIX NEW BIRDS FROM CELEBES AND JAVA. 



BY J. H. RILEY. 1 



Further study of the collection of birds made in Celebes 2 by 

 Mr. H. C. Raven has revealed the fact that five additional forms 

 from that island and one from Java apparently require names. 

 They may be known from the following descriptions: 



Excalfactoria chinensis palmeri, subsp. nov. 



Type, adult male, U. S. National Museum, No. 219,195, Daroe, Java, 

 June 20, 1909. Collected by William Palmer (original No. 1000). 



Similar to Excalfactoria chinensis lineata of the Philippines, but the back 

 and scapulars much mixed with slate color, the wing with much rufous, 

 and the rufous of the breast more extensive. Wing, 72; culmen, 11.5; 

 tarsus, 22; middle-toe, 18 mm. 



Remarks. — In a series of twelve males of Excalfactoria chinensis lineata 

 from the Philippines, there is no rufous in the wings, except in one and then 

 it is only slight. Two males from Celebes have some rufous in the wing 

 but not to the same extent as Javan birds; their backs resemble the Philip- 

 pine form. The Celebes bird is very small and apparently represents a 

 recognizable race that Gould 3 named and which will probably stand as 

 Excalfactoria chinensis minima. Of the mainland bird I have only one 

 male from the Malay Peninsula. It is like the Philippine form but much 

 lighter in color. 



Anas superciliosa percna, subsp. nov. 



Type, adult male, U. S. National Museum, No. 250,631, Koelawi, Cele- 

 bes, Feb. 3, 1917. Collected by H. C. Raven (original No. 3506). 



Similar to Anas superciliosa rogersi but smaller and averaging darker, 

 especially on the throat. Wing, 250; tail, 98; culmen, 52.5; tarsus, 43 

 middle-toe, 53 mm. 



Remarks. — In addition to the type, there are two males, two females, 

 and a downy young from the type locality taken February 2 and 3; two 

 males and two females from Dolo, December 26; one male from Winatoe, 

 January 21; and one male from Rano Lindoe, March 13.
