BIRDS FROM SIAM AND THE MALAY PENINSULA 131 



CHALCITES MALAYANUS MALAYANUS (Raffles) 



Cuculus malayanus Raffles, Trans. Linn. Soc. London, vol. 13, p. 286, 1822 

 (Malay Peninsula). 



One male, Yala, Patani, February 1, 1931. 



This form of cuckoo has not been taken north of Patani, whence it 

 was recorded by Ogilvie-Grant.^ Dr. Smith's specimen is apparently 

 the second record. In the Malay States it has been recorded more 

 frequently. 



The form ranges from Patani in Peninsular Siam to the Malay 

 States, Sumatra, Java, Borneo, the southern Philippines, and Celebes. 



Hartert and Stresemann,^ in their paper on the Indo-Australian 

 forms of the genus, divide Chalcites malayanus into 10 races, two un- 

 named. Tliej all occur on islands to the south of the range of the 

 Malay race and reach Australia. 



Dr. Smith's specimen from Patani has a longer wing than a male 

 from Java and two males from Pulo Panjang, Borneo. The wings 

 of the males in the United States National Museum measure as 

 follows: Patani, 98; Java, 94; Borneo, 90-93; Celebes, 90 mm. 



The female of this form is similar to the male but with an intensified 

 purple sheen to the green above. The pileum is like the back, a dull 

 bronzy green with purplish reflections; the middle tail feathers are 

 like the back, with a subterminal dusky tip. The female should not 

 be confused with the same sex of the other two members of the genus 

 occurring in Siam. The male is green above, with purplish-bronzy 

 reflections. 



SURNICULUS LUGUBRIS DICRUROIDES (Hodgson) 



Pseudornis dicruroides Hodgson, Journ. Asiat. Soc. Bengal, vol. 8, p. 136, 1839 

 (Nepal). 



One male, Hupbon, November 5, 1931 ; one male, Nong Yang, west 

 of Sriracha, November 6, 1931; one male, Nong Khor, near Sriracha, 

 March 22, 1926; one male, Tha Chang, west of Korat, March 20, 1927; 

 one male and one female, Kao Sabap, November 16 and 19, 1933; one 

 male, Kao Soi Dao, Trang, January 8, 1934. 



Dr. W. L. Abbott took a male on Pulo Langkawi, Langkawi Group, 

 December 3, 1899, that measures: Wing, 146.5; tail, 120; culmen, 20 

 mm. 



The wing of the Langkawi bird is longer than any in the series taken 

 by Dr. Smith in southeastern Siam and apparently belongs to the 

 northern form. It was taken in winter, and it is probable the northern 

 form may wander south at this season of the year; the male taken by 

 Dr. Smith in Trang apparently also belongs to the northern form. 

 The Kao Sabap male is small; wing, 134; it may be a bird of the year.
