BIRDS FROM SIAM AND THE MALAY PENINSULA 185 



thirds grown. They are hke the adults but, of course, have much 

 shorter bills. They evidently acquire the adult plumage at an earlier 

 age than Alcemerops amictus. 



The species ranges from India eastward to eastern Assam and south 

 into Burma, Siam, Laos, Tonldn, Annam, Cochinchina, and Cambodia. 

 It occurs nearly all over Siam proper and has been taken as far south 

 as Hat Sanuk by Robinson and Kloss ^^ and Koh Lak Paa by Count 

 Gyldenstolpe.-'* Deignan '^ reports that it is found on Doi Sutep 

 between 2,500 and 4,600 feet and also on the plain at Chiengmai. De 

 Schauensee ^^ secured specimens from Chiengdao, 5,000 feet, as well as 

 Doi Sutep, 4,500-5,550 feet, and Monghn, South Shan States, and 

 reports it everywhere rather scarce. It is a forest bird. 



A single male from Daban, southern Annam, received through C. 

 Boden Kloss, is considerably p^ler above and below, and the gorget is 

 less pronounced and a paler blue; the underside of the tail is noticeably 

 paler and the tip of the feathers dusky rather than blackish ; the shaft of 

 the tail feathers is ivory instead of lemon-yellow. 



ALCEMEROPS AMICTUS (Temminck) 



Mernps amicta Temminck, Nouveau recueil de planches colorizes d'oiseaux, livr. 

 52, pi. 310, 1824 ^Bencoolen, Sumatra). 



One male and one female, Kao Luang, 1,000 feet, Nakon Sritamarat, 

 July 23, 1928; one male, Tha Lo, Bandon, September 15, 1931; two 

 males and one female, Kao Soi Dao, Trang, December 20, 27, 1933, 

 January 25, 1934. 



Dr. W. L. Abbott collected four males and one female in Trang 

 (Prahmon, March 6, 1896; Tyching, July 21, 1896; Lay Song Hong, 

 September 20, 1896; Kao Soi Dao, 1000-2000 feet, February 11-18, 

 1899); and one female, Champang, Tenasserim, December 22, 1903. 

 He gives the soft parts as follows: Bill black, base of lower mandible 

 leaden; feet greenish leaden; iris orange-red. 



The species ranges from Tenasserim south thiough Peninsular Siam 

 to the Malay States, Sumatra, Banka, and Borneo. 



Besides the series mentioned above, the United States National 

 Museum contains the following: One male from east Sumatra, one 

 male and one female from Banka, three males and three females from 

 Borneo (only two of each sex adult) and one male from Selangor. 



The series from Borneo is not sufficient to show whether there is 

 any average difference in size between it and the mainland series. 

 There seems to be no constant difference in color. 



In the series of males before me, a narrow border around the bill is 

 caerulean blue in seven specimens, but with the mentum scheele green
