BIRDS FROM SIAM AND THE MALAY PENINSULA 241 



The above series is lighter and averages larger than a good series 

 from Peninsular Siam. 



Five males from eastern Siam measure: Wing, 235-250 (241.6); 

 tail, 139-162 (153.8); calmen, 62-67.5 (64.5) mm. Five females from 

 northern and eastern Siam: AVing, 235-242 (238.2); tail, 150-159 

 (154); culmen, 58-66 (62.3) mm. 



The form ranges from Oudh, Assam, Burma, and northern Tenas- 

 serim to Siam proper, Laos, Cambodia, Cochinchina, and Annam. 



I am somewhat doubtful of the Indo-China records; the only speci- 

 men examined in good plumage is a male from Trang Bom, Cochin- 

 china (no. 278359). It is a summer-taken specimen, slightly worn, 

 and is somewhat darker and a little smaller than this sex in the 

 Siamese series. It measures: Wing, 234; tail, 148; culmen, 57.5 mm. 

 On geographic grounds it is placed with the northern form for the 

 present. 



The bird of the year is lighter than adult specimens and has a rusty 

 wash to the plumage, which is retained until after it reaches adult size. 



The form occurs sparingly all over Siam proper. It has been re- 

 corded from Hat Sanuk, Rajburi, by Robinson and Kloss.^* This 

 must be near the limit of its range in this direction. 



MACROPICUS JAVENSIS JAVENSIS (Horsfield) 



Picus javensis Horsfield, Trans. Linn. Soc. London, vol. 13, p. 175, 1821 (Java). 



One male, Kao Soi Dao, Trang, January 6, 1934; one female, Tha 

 Lo, Bandon, September 23, 1931. 



The following were collected by Dr. W. L. Abbott: Four males and 

 three females in Trang (Prahmon, April 7, 1896; Lay Song Hong, 

 August 20-November 23, 1896; Trang, January 28, 1899); one male, 

 Kemamun, Trengganu, October 2, 1900; and one female, Endau 

 River, Pahang side, June 21, 1901. He gives the soft parts as: Iris 

 yellow, pale yellow, pale greenish yellow; bill black, black with white 

 at tip beneath, or black, grayish beneath; feet leaden, dull leaden, 

 dirty leaden, or leaden blue; claws dark brown; dark horn blue, or 

 blackish leaden. 



This form ranges from Java, Borneo, the Rhio Archipelago, Banka, 

 and Sumatra to the Malay States and north through Peninsular Siam 

 to southern Tenasserim. 



No specimens from Java have been available for comparison. 

 Birds from the Philippines appear to be smaller and break up into a 

 number of races. A large race, Macrojpicus javensis buttikqferi Rich- 

 mond, is found on Nias and a much smaller form, M. j. parvus Rich- 

 mond, on Simalur. 



The few specimens examined by me from Borneo seem to have the 

 throat and cheeks on the average more heavily streaked with white
