HEMIPROCNE » LONGIPENNIS HARTERTI Stresemann. 



Hemiprocne longipennis harterti Stresemann, Novit. Zool., vol. 20, June, 1913, 

 p. 339 (Deli, northeastern Sumatra). 



Two specimens: 



Adult male, No. 171070, U.S.N.M.; Pulo Jimaja, September 25, 

 1899. Length in flesh, 210 mm. "Feet dark brownish purple." 



Adult female, No. 171069, U.S.N.M.; Pulo Jimaja, September 18, 

 1899. 



Both are in process of molt, and though somewhat worn, seem to be 

 identical with birds from Sumatra and the Malay Peninsula, which 

 represent this newly described and readily distinguishable race. 

 Doctor Abbott reports that this bird was common in the mangrove 

 swamps of the Anamba Islands. 



There are now recognizable the following forms of Hemiprocne lon- 

 gipennis: 



Hemiprocne longipennis longipennis (Rafinesque). — Islands of Java 

 and Bali. 



Hemiprocne longipennis harterti Stresemann. — Islands of Sumatra, 

 Banka, Billiton, and Borneo, north to the Natuna Islands, Anamba
