BIRDS FROM SI AM AND THE MALAY PENINSULA 419 



MYOPHONUS CRASSIROSTRIS Robinson 



Myiophoneus crassirostns RobinsOxM, Bull. Brit. Orn. Club, vol. 25, p. 99, 1910 



(Trang, Peninsular Siam). 

 Myophonus tetniniuckii changensis Riley, Proc. Biol. Soc. Washington, vol. 41, 



p. 207, 1928 (Koh Chang, Siam). 



One adult male, Koh Chang, January 6, 1926; one adult male, Kao 

 Kuap, Krat, December 27, 1929 ; one female, Kao Sabap, November 18, 

 1933; one immature male, Kao Luang, 1,000 feeet, Nakon Sritamarat, 

 July 23, 1928. 



Dr. W. L. Abbott collected a male on Pulo Terutau, Langkawi 

 Group, April 1, 1904. 



The male from Kao Kuap is a lighter, more purplish bird than the 

 Koh Chang male; both have white tips to the greater wing coverts. 



The male collected by Dr. Abbott that I formerly took to represent 

 typical crassirostris is a totally different-looking bird from either of 

 the two above males. It is more of a dusky violet-blue, both above 

 and below, and lacks the white tips to the greater wing coverts, but 

 in describing changensis I overlooked the fact that in the original 

 description crassirostris was also said to have white tips to the greater 

 wing coverts. Now I think it best for the present to adopt Mr. 

 Kloss's view ^^ that the Terutau male may represent a plumage phase 

 and place changensis in synonymy. 



The type came from Trang, and it has been taken on Langkawi 

 and Terutau;^* Koh Muk (Pulo Muntia), Trang, and Pasir Raja 

 (Pulo Lontar), southwestern Siam '^; Nong Kok, Ghirbi, Peninsular 

 Siam.^^ 



This would give it a range from Trang, Peninsular Siam, to south- 

 eastern Siam. 



The immature male from Kao Luang, mentioned above, is dusky 

 slate-violet above without lighter tips to the feathers, and blackish 

 below; the feathers of the breast with white shafts basally; the bill 

 thick and heavy as in the adult. 



The adult can be distinguished from M. temminckii by the thick 

 heavy bill ; from eugenei by the heavier bill and the white bases to the 

 feathers of the breast and flanks.
