BIRDS FROM SIAM AND THE MALAY PENINSULA 127 



Eobinson ^^ reports the taldng of a male on Koh Muk, Trang, 

 January 4, 1917; Robinson and Kloss ^° list it from Kao Luang, 

 2,000 feet, Nakon Sritamarat, and also ^' a male and immature 

 female from Tapli, Pakchan, taken March 4, 1919. Judged from the 

 records, it is probably not a common permanent resident. 



The range of the form is Peninsular Siam, the Malay States, Sumatra 

 Java, Bah, Lombok, Sumbawa, Sumba, and the Philippines, except 

 the Sulu Islands. 



PENTHOCERYX SONNERATII SONNERATII (Latham) 



Cuculus sonneratii Latham, Index ornithologicus, vol. 1, p. 215, 1790 (India). 



One male and one female, Chiengmai, November 27, 1928; one 

 male and one female, Muang Pai, December 28, 1932; one female, 

 Hupbon, October 31, 1931. 



Deignan ^^ reports it unconmion in winter on Doi Sutep to 4,600 

 feet and on the plain; Chasen and Kloss ^^ record it from the Raheng 

 District; Gyldenstolpe ^'^ lists it from Bangkok and later *^ from Pa 

 Hing, northern Siam; Stuart Baker ^^ records it from Hupbon, south- 

 eastern Siam. 



Apparently tliis cuckoo is an uncommon bird in Siam. It ranges 

 from India to Burma, Assam, Siam, South Annam, and Cochinchina, 

 and south to central Tenasserim.

Penthoceryx sonnerati malayanus Chasen and Kloss, Bull. Raffles Mus., no. 5, 

 p. 84, 1931 (Kuala Lumpur, Selangor). 



Dr. W. L. Abbott collected two males in Trang, January 27, 1897, 

 and January 20, 1899. He gives the soft parts as follows: Iris brown; 

 feet leaden with a greenish tinge ; bill black above, dull leaden brownish 

 at base beneath. 



These two males measure: Wing, 112-119.5; tail, 99-103; culmen, 

 19.5-20 mm. Two males of P. s. sonnerati collected by Dr. Smith in 

 northern Siam measure: Wing, 128.5-133; tail, 120-128; culmen, 

 21-21.5 mm. Three females (2, northern Siam; 1, southeastern 

 Siam): W^ing, 126.5-130 (128.2); tail, 116.5-127 (121.7); culmen, 

 20-22 (21 mm). Apparently there is little difference between the 

 sexes.
