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,

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.
