Dr. W. L. Abbott collected the following specimens: One male and 

 four females, Trang, January 20, 21, and February 5, 1897, February 

 23 and March 4, 1899; one male and one female, Pulo Lankawi, 

 December 4, 9, 1899; two males, Mergui Archipelago (Domel Island, 

 February 24, 1900; Hastings Island, December 11, 1900). 



In the considerable series of this species in the United States 

 National Museum there is a male (no. 278528) taken at Dran, South 

 Annam, at 3,000 feet, May 10, 1918, by C. Boden Klcss. It is in 

 worn breeding plumage and is drab above rather than the hair brown 

 of the majority of the series; below the pectoral band is indicated only 

 by a few drab streaks; bill larger. It measures: Wing, 71; tail, 47.5; 

 culmen, 12 mm. Possibly there may be a resident form in the 

 mountains of South Annam. 



A. I. latirostris breeds in east Siberia west to Lake Baical and in 

 the northern Japanese Islands; in fall it migrates through southein 

 China, Indo-China, and Siam to the Greater Sunda Islands and some 

 of the Philippines. It occurs practically all over Siam in winter }md 

 down Peninsular Siam to the Malay States. Apparently it rem; ins 

 in Siam until rather late in spring, as Dr. Smith took it at Bangkok as 

 late as April 28; it is very doubtful whether it remains to breed.
