BIRDS FROM SI AM AND THE MALAY PENINSULA 165 



HARPACTES DIARDU NEGLECTUS (Forbes and Robinson) 



Pyrotrogon neglectus Forbes and Robinson, Bull. Liverpool Mus., vol. 2, no. 1, 

 p. 34. 1899 (Malacca, Pahang). 



One female, Kao Luang, 2,000 feet, Nakon Sritamarat, July 22, 

 1898; one female, Sichol, Bandon, May 15, 1930; one male, Kao Soi 

 Dao, Trang, December 29, 1933. 



Dr. W. L. Abbott collected two males and two females in Trang 

 (Lay Song Hong, September 2 and December 22, 1896; Kao Soi Dao, 

 1,500 feet, February 14, 1899; Kok Sai, 500 feet, December 1898); one 

 male, Tanjong Dungun, Trengganu, September 22, 1900; one adult 

 male, one mimature male, and one female, east coast of Johore (Endau 

 River, July 9 and 19, 1901; Sembrong River, July 4, 1901); one male, 

 Province of Weliesley, Straits Settlements (purchased in Penang). 

 He describes tlie soft parts as: Male — bill blue, black at the tip and 

 along culmen; orbital skin lilac; iris dark red; feet leaden; in the 

 female, the iris is dark brown. 



In this form the male has the head, throat, and foreneck black; a 

 pink band across the nape; the tips of the outer tail feathers white, 

 stippled with black; breast and belly scarlet; back ochraceous-tawny; 

 middle tail feathers russet. In the female the head, throat, and fore- 

 neck are like the back or only slightly darker. In either sex the form 

 can be distinguished from the other trogons inhabiting the Malay 

 Peninsula by the white, stippled with black, tips to the outer tail 

 feathers. 



Two adidt males from Banka and two adult males from Sumatra 

 in the United States National Museum have the whole pileum washed 

 with deep red, while in the five adult males from the Malay States 

 listed above this wash is faint and confined to the nape. One of the 

 males from Banka (no. 180457) is almost, if not quite, as strongly 

 marked with red on the pileum as Bornean specimens. On the whole, 

 the Banka-Sumatran series seems to be lighter on the back than the 

 series from the Malay States. I believe the mainland bird should be 

 treated as a separate form from the one occurring in Sumatra. 

 Blasius ^^ described Harpades diardii sumatranus from Sumatra and 

 the Malay Peninsula. I definitely designate the type locality as 

 Sumatra. This will bring Forbes and Robinson's name into use again 

 for the mainland form. 



Harpades diardii negledus ranges from the Federated Malay States 

 northward tlirough Peninsular Siam to Bandon and possibly a little 

 farther north. 



Harpades diardii diardii (Temminck) is confined to Borneo and 

 Banka, and Harpades diardii sumatranus Blasius inhabits Sumatra.
