THE BIRDS OF THE NATUNA ISLANDS 



59 



axillars wax yellow; rest of lining of wing dull brownish white, the 

 edges of the wings fuscous overlaid with wax yellow. 



This new race seems to be readily distinguishable from Culicicapa 

 ceylonensis ceylonensis and from the other recognizable forms of the 

 species. Although our series from Borneo is not entirely satisfactory, 

 the birds from that island seem to belong also to the Natuna Islands 

 subspecies. There is apparently no material sexual difference. 



The five specimens collected by Doctor Abbott are listed below: 



Adult male (type), U.S. N.M. No. 174834; Gunong Ranay, Bung- 

 uran Island, July 2, 1900. 



Adult male, U.S.N.M. No. 174835; Bunguran Island, July 2, 1900. 



Adult male, U.S.N.M. No. 174831; Bunguran Island, July 4, 1900. 

 ^'Bill black above, pale fleshy brown beneath; tarsi fleshy brown; 

 toes brownish orange." 



Adult female, U.S.N.M. No. 174832; Bunguran Island, July 18, 

 1900. 



Adult female, U.S.N.M. No. 174833; Bunguran Island, July 2, 1900. 



There is some individual variation in the color of the pileum in 

 these examples, this part varying from dark mouse gray to blackish. 

 There are indications of molt among the contour feathers of all, and 

 among the ^^^ng quills of two — Nos. 174833 and 174835. 



Doctor Abbott found this flycatcher in the heavy forest on Bung- 

 uran Island. Doctor Hartert has recorded it ^^ from Pulo Panjang. 



Measurements of the Natuna Islands specimens collected by Doctor- 

 Abbott are given in Table 17.

Including the race above described there are now at least 10 

 recognizable subspecies of Culicicapa ceylonensis, as follows:
