BIRDS FROM SIAM AND THE MALAY PENINSULA 197 



These are the only definite records I have seen for Si am. The 

 species ranges from southern Tenasserim through Peninsular Siam 

 to the Malay States, Sumatra, and Borneo. 



RHINOPLAX VIGIL (Forster) 



Buceros vigil Forster, Indische Zoologie, p. 40, 1781 (Tenasserim). 



Dr. W. L. Abbott collected one male and two females at Lay Song 

 Hong, Trang, September 16, 24, and November 21, 1896. He gives 

 the color of the soft parts as: Male — iris dark red; front of casque and 

 distal part of beak yellow, rest of casque and bill dark crimson; naked 

 skin of neck and back dull dark crimson; feet brownish red, claws 

 homy brown at tips, paler toward bases and becoming dull greenish 

 horny. Female — similar to the male, chin brown; tliroat pale blue, 

 neck bluish white; tarsi brownish leaden behind, brick red in front; 

 claws pale yellow-brown, tips brownish black. The weight of the 

 male is given as 5K and that of the two females as 5^^ and 6K pounds. 

 He notes the male as very thin. 



The species ranges from Borneo and Sumatra to the northern Malay 

 States and northward through Peninsular Siam to southern Tenas- 

 serim. Robinson and Kloss '^^ state that it is fairly common in heavy 

 jungle in the Malay States, but never very easy to obtain.

CALORAMPHUS FUUGINOSUS HAYI (Gray) 



Bucco hayi Gray, Zool. Misc., 1831, p. 33 (Malacca). 



Three females, Sichol, Bandon, May 19, 1930; one female. Hoi Tah, 

 Kao Luang, Nakon Sritamarat, July 18, 1928; three females, Wat 

 Kiriwong, Nakon Sritamarat, July 25, 1928. 



Dr. W. L. Abbott collected seven males, five females, and one 

 unsexed in Trang (Lay Song Hong, September 2-3, 1896; Chong, Jan- 

 uary 23, 1897); and two males on the Rumpin River, Pahang, June 

 10-11, 1902. 



Two of the females collected by Dr. Smith at Sichol have larger bills 

 than the rest of the series. They measure 23.5 and 24 mm, while in 

 the other females, from farther south, the culmen measures 20-22.5 

 mm. There might be a larger race in the north, but for the present 

 I prefer to regard the larger bills of the two females as due to individual 

 variation. 



All Dr. Abbott's specimens sexed as males have black bills, while 

 the females have brown bills, and his notes on colors of the soft parts 

 confirm this sexual difference. 



Two males and three females from Sumatra have somewhat more 

 reddish throats than the mainland specimens, but the difference is
