BIRDS FROM SIAM AND THE MALAY PENINSULA 303 



This series agrees fairly well with specimens from Java. The 

 five males from the Malay Peninsula measure: Wing, 330-350 

 (341.6); culmen, 62-67 (65.2) mm. One male and two females from 

 Java: Wing, 330-356 (340.3); culmen, 60-05 (62.3) mm. 



In this form the bill is highly arched, longer and heavier than in 

 C. m. andamanensis. 



Just how far north in Peninsular Siam this race extends I do not 

 know. Robinson and Kloss ^ record it from Tapli. From there 

 southward apparently it is the common and only crow, except in the 

 Malay States. 



Its range is Peninsular Siam to the Malay States, Sumatra, Java, 

 and the islands east to Sumba and Flores. Robinson ^ records it 

 from Koh Samui and Koh Pennan, off Bandon; and from Pulo 

 Langkawi and Pulo Telibun.' 



UROCISSA ERYTHRORHYNCHA MAGNIROSTRIS (BIyth) 



Psilorhinus magniroMris Blyth, Journ. Asiat. Soc. Bengal, vol. 15, p. 27, 1846 

 (Youmadoug Hills, Arakan). 



One male, Doi Angka, 2,000 feet, December 8, 1928; one male, 

 Doi Muso, December 29, 1932; one female, Mae Suya Valley, January 

 2, 1933; one female, Muang Pal, December 28, 1932; two males, Pak 

 Chong, February 8, 1925, May 2, 1926; two males, Pang Sok, August 

 15, 23, 1926; one unsexed, Chantuk, June 15, 1934; one female, Sikeu, 

 near Korat, March 2, 1926. Dr. Smith gives the soft parts as: Iris 

 brown; bill and legs coral red. 



I confirm de Schauensee's remarks ^^ that both U. e. magnirostris 

 and U. e. erythrorhyncha have white tips to the primaries, but that 

 in the latter they are smaller. In specimens showing some wear 

 they may be nearly worn off. 



U. e. magnirostris is not an uncommon bird in northern and eastern 

 Siam. Chasen and Kloss ^^ record it from the Raheng District; 

 Keddie '^ from the Meklong, western Siam. 



The form ranges from the hills of Arakan east to Burma, western, 

 northern, and eastern Siam. De Schauensee says they are birds of 

 the deciduous forests not ranging higher than 2,000 feet in the winter. 

 Deignan '^ found them on Doi Sutep to 2,700 feet.
