BIRDS FRO:\I SIAM AND THE MALAY PENINSULA 217 



Dr. Smith describes the soft parts of a male from Nong Khor as: 

 Iris reddish brown; bill black above, yellow below. 



This form is lighter above and below than C. c. chlorolophoides ; the 

 nuchal crest is paler; and it averages somewhat smaller, especially 

 the bill. Six males measure: Wing, 127.5-137.5 (132.4); tail, 80-90. 5 

 (86.4); culmen, 24.5-26.5 (25.7) mm. Six females: Wing, 125-136 

 (131.4); tail, 85-92 (88); culmen, 23.5-26 (24.8) mm. 



Ten males of C. c. chlorolophoides measure: Wing, 131.5-142 (135.8); 

 tail, 84-96 (89.9); culmen, 24.5-30.5 (27.8) mm. Ten females: Wing, 

 134-140 (136.7); tail, 87.5-100 (94.3); culmen, 25-28 (26.6). 



Two males of C. c. krempji from Trang Bom, Cochinchina, are 

 somewhat darker and smaller than C c. conjundus. They measure: 

 Wing 126-129; tail, 85-90; culmen, 24.5-26 mm. 



The immature male of Cirropicus chlorolophus has the chest brown- 

 ish and the crown as well as the forehead with red tips to the feathers. 

 This brownishness of the chest and red on the crown persist some time 

 after the birds reach adult size. Judged by this criterion, the male 

 from Pak Chong and the male from Kao Seming are immature. The 

 chest in the latter is becoming greenish, and it has lost most of the red 

 tips to the crown feathers; it was taken January 2. The Pak Chong 

 male, taken May 5, has the whole chest and throat olive-brown and 

 the bars on the breast and belly lightly indicated hair brown. 



C. c. conjundus is apparently confined to eastern and southeastern 

 Siam. It probably ranges into Cambodia also, but I have seen no 

 records from there. 



A closely related form, Cirropicus chlorolophus krempji (Delacour 

 and Jabouille) occurs in Cochinchina; C. c. annamensis (Meinertz- 

 hagen) in southern Annam; C. c. laotianus (Delacour and Jabouille) in 

 Tonkin, northern Annam, and northern Laos; C. c. citrinocristatus 

 (Rickett) in central Fohkien, China. C. c. rodgeri (Hartert and Butler) 

 is an isolated form inhabiting the mountains of Perak.

 Malay States Mus., vol. 10, pt. 3, p. 204, 1921 (Tapli, Pakchan Estuary,

 Patani, July 5, 8, 1926. 



Dr. Abbott collected two males and four females in Trang (Prah- 

 mon, March 23, April 2, 1896; Lay Song Hong, August 18, 31, 1896; 

 Trang, February 24, 1899); one female, Dungun River, Trengganu, 

 September 22, 1900, and one male, Rumpin Rivei, Pahang, June 21,
