360 Mr. Blyth's Commentary 



p. '67, note (from China and Formosa) ; also C. tenuirostris and 

 C. lepidus of Miiller. C. vionusijllabicus, Swinhoe, Ibis, 1865, 

 p. 545, is probably yet another synonym. 



Mr. Wallace has examples from Java, Batchian, Celebes, 

 Flores, and Timor. Himalayan examples agree exactly with 

 Mr. Gould's figure of an Australian specimen. 



201. CucuLUS POLiocEPHALUS, Lath. ; C. intermedius,ydi\i\; 

 " C. tenuirostins, Lesson,^' Cassin; C. fuscatus, Peabody (Ornitho- 

 logy of Wilkes's U. S. Exploring Voyage, pi. 21. f. 1). 



Specimens from Java, in Mr. Wallace's collection, are per- 

 fectly similar to those from the Himalaya, Nilgiris, and 

 mountains of Ceylon. 



202. CUCULUS SONNERATI. 



This is a very distinct species (as observed by Dr. Jerdon and 

 myself), which never assumes the grey phase of plumage when 

 adult, and is conspicuously dififerent from the young of C. poli- 

 ocephalus, with which Prof. Schlegel identifies Dr. Jerdon's 

 bird, though recognizing the same species afterwards and 

 noticing it as diffused from India and China to the Indian 

 Archipelago and Austi-alia. I have only seen it from Malabar, 

 Ceylon, the Tenasserim provinces, and Malayan Peninsula, but 

 the young of C. poliocephalus often enough from the Himalaya. 

 It may be remarked that adults of C. poliocephalus, especially 

 females, assume the hepatic phase of plumage very commonly, 

 those of C. striatus much more rarely, and of C. canorus very 

 rarely. The Chok-gallos, or Hawk-like Cuckoos [Hierococcyx) , 

 and the Bhokatdko-^YOxx^ never assume the hepatic phase of 

 plumage, which again is common in the species of Polyphasia 

 [Cacomantis) and ChrysQCOCcyx. 



203. CuCULUS MICROPTERUS. 



Hah. All India, with Ceylon, the Himfilaya, Tenasserim 

 provinces, Cambogia, China, and Java. 



204. CuCULUS AFFINIS. 



From the Himalaya and Malayan Peninsula. This and the 

 preceding race differ only in size ; and the larger, C. affinis, I 

 have only seen from the localities named, though numerous
