Mr. Blyth’s Commentary 
p. 37, note (from China and Formosa) ; also C. tenuirostris and 
C. lepidus of Muller. C. monosyllabicus , Swinhoe, Ibis, 1865, 
p. 545, is probably yet another synonym. 
Mr. Wall ace 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. intermedins, V ahl; 
“ C. tenuirostris, 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 Hr. Jerdon and 
myself), which never assumes the grey phase of plumage when 
adult, and is conspicuously different from the young of C. poli- 
ocephalus, with which Prof. Schlegel identities Hr. Jerdon’s 
bird, though recognizing the same species afterwards and 
noticing it as diffused from India and China to the Indian 
Archipelago and Australia. 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 [flier o co ccyx), 
and the Bhokatako-gvowp never assume the hepatic phase of 
plumage, which again is common in the species of Polyphasia 
(Cacomantis) and Chry so coccyx. 
203. CUCULUS MICROPTERUS. 
Hab . All India, with Ceylon, the Himalaya, Tenasserim 
provinces, Cambogia, China, and Java. 
204. Cuculus APFINIS. 
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
