A set of two eggs was taken at Sikeii, March 1, with the male parent. 

 They are oval, cartridge buff, and quite glossy. They measure 24.4 

 by 21 and 24.7 by 20.3 mm. 



Dr. W. L. Abbott collected the following: Two males and tw^o 

 females, Trang (Prahmon, April 10, 1896; Lay Song Hong, September 

 15, 1896, and January 1, 1897; Trang, January 29, 1897); one male, 

 Pulo Langkawi, December 8, 1899; one male, Pulo Tenitau, Novem- 

 ber 14, 1903; two females, Tenasserim (Victoria Point, December 17, 

 1900; Sungei Balik, February 25, 1904). He gives the color of the 

 soft parts as: Bill horn blue, tip and culmen black; feet leaden; orbital 

 skin blue; ii'is dark browTi. 



The males from northern and eastern Siam differ as follows from 

 the four males from Peninsular Siam: The pileum, throat, and chest 

 are more of a light cadmium, not so dusky; the back is a lighter 

 brown; and the tail is longer. 



Robinson and Kloss ^^ state that birds from the southern Malay 

 Peninsula differ very slightly from those from farther north in having 

 the bars on the secondaries and wing coverts rather closer together. 

 No specimens from the Malay States have been available for exami- 

 nation, but three males and one female from the Island of Nias, off 

 western Sumatra, agree quite closely with Peninsular Siamese birds. 



Three males from Nias measure: Wing, 119-121 (119.7); tail, 

 137-144 (140.7); culmen, 16-17 (16.7) mm. Four males from 

 Peninsular Siam: Wing, 115-125 (120.7); tail, 136.5-156 (147.9); 

 culmen, 15.5-17 (16.2) mm. Ten males from eastern Siam: Wing, 

 114-122.5 (118.5); tail, 154-174 (163.8); culmen, 15-16 (15.4) mm. 



The form ranges from Nias, Sumatra, and the Malay States north- 

 ward through Peninsular Siam to Tenasserim and northern Siam, 

 and eastward through eastern Siam to Laos, Cambodia, Cochin- 

 china, and Annam. The eastern bird should probably be separated 

 from the one occurring in Peninsular Siam, but I do not wish to do so 

 at present. The form is generally distributed /all over Siam proper, 

 Peninsular Siam, and many of the islands off the coast. 



Gyldenstolpe ^* took a set of two eggs near Pak Koh on March 11, 

 1914. He describes the eggs as cafe-au-lait in color and gives the 

 measurements as 23.7 by 20.5 and 23.2 by 20.5 mm. He also says 

 that this trogon is generally distributed over the whole of northern 

 Siam. Gairdner ^^ records it from the Petchaburi District, and 

 Barton ^^ from the Raheng District. 



Harpades oreskios oreskios (Teniminck) is confined to Java and 

 Harpades oreskios dulitensis Grant to Borneo.
