1,000 feet, February 20, 1899); one male, the Dindings, Straits of 

 Malacca, April 14, 1900; one male and one female, Endau River, east 

 coast of Johore, June 28 and July 13, 1901; and one male, and two 

 females, Rumpin River, Pahang, June 2, July 11, 22, 1902. 



Dr. Abbott gives the soft parts as: Iris reddish brown, dark red, or 

 deep crimson; bill black above, leaden below; greenish at the base of 

 lower mandible; feet dull green, pale green, or olive green; orbital 

 skin green, dull green, or pale green. 



The male apparently differs from the female only in having the 

 malar region dusky with buffy spots (the malar region in the female 

 being hazel without spots). A male collected by Dr. Abbott on the 

 Rumpin River, Pahang, Jidy 11, has the malar region unspotted and 

 the breast and belly olive-brown with a slight citrine wash. It is 

 probably a bird of the year. 



This form ranges from southern Tenasserim through Peninsular 

 Siam to the Malay States, Sumatra, and Banka. Robinson and 

 Kloss ^^ state that it is rare in the northern part of the Peninsula, 

 barely reaching Bankasoon, Tenasserim. Judged by the number of 

 specimens collected by Dr. Abbott and Dr. Smith, it is probably 

 not uncommon in the south. 



Chryso2)hle<jm.a humii saha Chasen and Kloss inhabits Borneo. 



C. mentale (Tcmminck) of Java is larger and quite distinct from the 

 forms inhabiting Borneo and the mainland and in my opinion should 

 rank as another species. 



CHRYSOPHLEGMA FLAVINUCHA LYLEI Kloss 



Chrysophlegma flavinucha lylei Kloss, Ibis, 1918, p. 110 (Koh Lak, southwestern 

 Siam). 



One male, Doi Hua Mot, September 6, 1934; one male and two 

 females, Khun Tan, 4,000 feet, October 22, 1929, February 17, 1932; 

 two males, Khun Tan Mountains, 3,000-4,000 feet, November 21, 

 1928; May 16, 1933; one female, Sobpung, December 21, 1932; one 

 male, Kwe Noi, Kanburi, September 21, 1929. 



I have only one male of C . j . flavinucha with which to compare the 

 above series. The Siamese specimens have the throat and nuchal 

 crest lighter; the back greener; the forehead a darker reddish brown; 

 the chest darker; and the breast darker, more of a light citrine drab. 

 The increased white on the foreneck in the Siamese race, mentioned 

 in the original description, does not hold. 



Chasen and Kloss ^^ record it from the Raheng District, and a male 

 from their collection is in the United States National jMuseum; they 

 have also recorded it from Doi Sutep, 4,600 feet.^^ De Schauensee ^*
