Three other forms have been described from islands to the westward 

 and to the southeast. 



The form is readily distinguished from the two other species of the 

 genus occurring in Peninsular Siam by the light grayish throat and 

 chest, becoming white on the breast and belly; there are no dark nuchal 

 stripes. 



MACRONUS PTILOSUS PTILOSUS Jardine and Selby 



Macronus ptilosus Jaedine and Selby, Illustrations of ornithology, pi. 150, 1835 

 (Malacca). 



Five males and one female, Bangnara, Patani, July 11-21, 1926; 

 three males, Sicliol, Bandon, May 28, 1930. 



Two of the males from Sichol have the under mandible yellow, 

 instead of black, and are probably birds of the year. 



Dr. W. L. Abbott collected the following in the Malay Peninsula: 

 four males, Rumpin River, Pahang, May 25-June 25, 1902; one male, 

 Endau River, Pahang, June 27, 1901; one male, Tanjong Dungun, 

 Trengganu, September 21, 1900; one male and one female, Dungun 

 River, Trengganu, September 22, 1900. He describes the soft parts 

 as: Iris brownish red; naked skin about eye pale blue; naked skin on 

 sides of throat dark blue; bill black; feet black or brownish black. 



The form occurs from Sumatra to the Malay States and northward 

 in Peninsular Siam to Bandon. A somewhat lighter colored form, 

 M. p. reclusus Hartert, occurs in Borneo; and another, M. p. minor 

 Riley, in Banka. 



Ten males from the Malay Peninsula measure: Wing, 64-70 (67.2); 

 culmen, 15-17 (16) mm. Five males from Sumatra: Wing, 66.5-71 

 (67.7); culmen, 15.5-17 (16.2) mm. 



This is a curious little brown bird with long decomposed flank and 

 rump feathers with stiffened shafts; on the sides of the neck on each 

 side there is a large bare tract with a patch of white, downy, decom- 

 posed feathers in the center; the throat is black and the pileum burnt 

 sienna. 



KENOPIA STRIATA (BIyth) 



Timalia striata Blyth, Journ. Asiat. See. Bengal, vol. 11, p. 793, 1842 (Malay 

 Peninsula). 



Dr. W. L. Abbott collected the following in Trang, Peninsular Siam: 

 two adult males and two immature females. Lay Song Hong, Septem- 

 ber 12-December 5, 1896; two males, hills of Trang, February 3 and 4, 

 1897; one male and one female, "Trang", February 6 and 27, 1897. 

 He gives the soft parts as: Bill black, whitish at base of lower man- 

 dible; feet pale pinkish fleshy. 



Two of the specimens are immature and were taken September 12. 

 They are more than half grown, but the tails are not far bej'ond the 

 coverts. They resemble the adult above, except that the black on the 

 pileum is restricted and more chocolate-brown than black; below the
