July 14, 1928; two males, Kao Cliong, Trang, September 1, 9, 1933; 

 five males, Kao Soi Dao, Trang, December 31, 1933; January 5, 7, 

 1934 ; one male, Patalung, July 7, 1929. 



Dr. W. L. Abbott collected six males and six females in Trang 

 (Telibon Island, February 28, 1896; Prabmon, February 26, March 

 6-10, 1896; Tyching, July 22, 1896; Lay Song Hong, November 6 and 

 December 18, 1896; Trang, January 3, February 5, 19, 1897; Kok Sal, 

 December 28, 1898); three males and one female, Mergui Archipelago, 

 1900 (St. Matthew Island, January 16; St. Luke Island, January 21; 

 Loughborough Island, January 23); and one male. Red Point, Tenas- 

 serim, February 23, 1904. He also took a set of two eggs in Trang, 

 February 19, 1897. He gives the soft parts as: Iris red or orange; bill 

 and feet black. 



None of the males from the Malay Peninsula in the above series has 

 the under tail coverts come within an inch or more of the tip of the tail. 



One of Dr. Abbott's males from Lay Song Hong, Trang, November 

 6, is immature. It resembles the female in plumage but is a deeper blue 

 and the wings are darker; the rump feathers have the tips of the 

 feathers a shining blue, not to the same extent or as deep a color as 

 the adult, however. The specimen is of about adult size. 



Four of Dr. Smith's males are immature. They are of about adult 

 size and were collected as follovv's: Three in Koh Chang, Januar}^ 11 

 and March 10, and one, Khun Tan, February 19. One is like the 

 specimen collected by Dr. Abbott; the other three have some scattering 

 black feathers appearing on the lower parts, mostly on the throat and 

 sides of face; above there are some scattering shining blue feathers 

 appearing on the pileum, hindneck, and rump, these feathers being of a 

 lighter blue than in the adult, however. 



This form has a wide range, being found in India, Assam, Burma, 

 In do-China, Siam and down the Peninsular Siam to Trang or some- 

 what farther. In Siam it is evidently a common resident bird all over 

 the country and on the islands off the coast.

 1899, and a female at Tanjong Laboha, Trengganu, September 28,

In this form the under tail coverts reach to within a short distance 

 of the tip of the tail. It seems to be confined mostly to the Malay 

 States.
