Two sandpipers collected at Obando, Bulacan Province, Luzon, 
in 1910 were doubtfully identified as Tringa canutus as they are 
smaller in all measurements than the Asiatic knot. Dr. C. W. 
‘Richmond, of the United States National Museum, has kindly 
examined these two specimens and has labeled them Canutus 
canutus rogersi. The lower parts of No. 7378 are mottled with 
ochraceous buff and the upper parts retain a few scattered, 
worn, black feathers of the summer plumage. This specimen 
measured 250 millimeters in length in the flesh. The other 
specimen, which was collected a day earlier, is in complete, fresh, 
winter plumage.
