CACOMANTIS MERULINUS QUERULUS Heine 



Cacomantis querulus Heine, Journ. fiir Orn., 18G3, p. 352 (Farther India and 

 Nepal) . 



One adult male, Prae, April 10, 1930; one adult male, one immature 

 male, and two immature females, Bangkok, October 31, 1923, Septem- 

 ber 3, 1924, August 3, 1926; one immature (not sexed). Pong, Udon, 

 February 17, 1929; one adult male, Nong Khor, near Sriracha, March 

 24, 1926; one immature male, Koh Lak, June 22, 1933; one male, Kao 

 Soi Dao, Trang, January 13, 1934; one immature male and one 

 immature female, Bangnara, Patani, July 14 and 17, 1926. Dr. Smith 

 also collected an adult male at Vientiane, Laos, February 23, 1929. 



Dr. Abbott collected an immature female at Boyces Point, Tenas- 

 serim, February 12, 1904. This specimen has just commenced to 

 change on the pileum and the throat to the adult plumage. It is 

 much lighter on the lowerparts and back than fall-taken immature 

 females but shows little or no wear. 



Deignan ''^ reports that at Chiengmai it occurs throughout the year 

 but that it is rare from September to February; Chasen and Kloss " 

 record it from Raheng, western Siam; Robinson and Kloss ^^ say that 

 it appears to be present in the Peninsula throughout the year but 

 that its numbers are greatly augmented during the winter months. 



The form ranges from eastern Bengal, Assam, and Burma, to Yun- 

 nan, southern China, Tonkin, Laos, Annam, Cambodia, Siam, and 

 Peninsular Siam as far south as Patani. It is migrant in the northern 

 part of its range but resident in the southern; its numbers in the 

 south are augmented in the winter months by northern migrants. 



Cacomantis merulinus threnodes Cabanis and Heine, a smaller, paler 

 form, inhabits the Malay States, Sumatra, and the Mentawi Islands. 

 So far as known, it has not been taken in Peninsular Siam, but it may 

 occur along the southern border. 



CACOMANTIS SEPULCRALIS SEPULCRAUS (MUlIer) 



Cuculus sepulcralis S. Muller, Verhandelingen over de natuurlijke Geschiedenis 

 der Nederlandsche overzeesche bezittingen . . ., p. 177, note, 1839-44 

 (Java and Sumatra). 



Dr. W. L. Abbott purchased an immature specimen in Penang, 

 said to have been shot in the Province of Wellesley. I place it here 

 with some doubt. 



This is a darker and somewhat larger cuckoo than C. merulinus 

 querulus; the chest is darker, and the cinnamon color extends farther 

 forward, almost to the chin; the wliite notching on the inner webs of 

 the outer tail feathers does not reach the shaft.
